Trade/Device Name: Easy Brush with Fluoride Regulation Number: 21 CFR 872.6855
The Easy Brush with fluoride is intended to mechanically remove plaque and food particles from between teeth to reduce tooth decay. It is to be used with an in and out motion to clean between interdental space as it is done with floss, and other interdental cleaners such as tooth picks.
The Easy Brush with fluoride is an interdental brush designed to clean between teeth. It is composed of 4 parts (a handle, a wire, bristles, and a cap). The wire is twisted around the nylon filaments to create the brush, and then is molded onto a plastic handle. It is then coated with a solution containing flavor and sodium fluoride and then capped off.
This document describes DenTek Oral Care Inc.'s Easy Brush with fluoride. However, the provided text does not contain any information about acceptance criteria or a study proving the device meets acceptance criteria.

Re: K121165
Trade/Device Name: Beam Brush/Beam APP Regulation Number: 21 CFR 872.6855
The Beam Brush is a toothbrush to remove plaque and debris from its user's teeth and aide in the prevention of tooth decay. The Beam Brush collects brushing usage data and wirelessly transmits the data to a software application (Beam App) that runs on the user's own mobile device ("smartphone").
The Beam Brush is a manual toothbrush comprised essentially of a shaft with synthetic bristles on one end that are used to remove plaque and food debris from its user's teeth. The bristle material is Nylon 612 or Polyamide 612. The Beam Brush collects brushing usage data based on the principle that the human body possesses the property of being a good capacitor, such that the human body has a detectable capacitance. This capacitance is transferrable through a thermoplastic material. The Beam Brush comprises a capacitive sensor, which is completely enclosed in the toothbrush body. The capacitive sensor detects that the Beam Brush is in use based on the capacitance introduced by the human body when the Beam Brush is utilized for its intended purpose. The Beam Brush wirelessly transmits the collected data using radio frequency transmission, more specifically Bluetooth® radio. The Bluetooth® standard defines the parameters for transmission of data via radio frequency including a transmitting frequency of 2.4 GHz. The Beam Brush is a Class 2 Bluetooth® device, which has a transmission range of about 30 feet and a maximum power of 2.5 mW. The data is received by a user's own mobile device that runs a software application (Beam App), which is of a minor level of concern. The Beam App is an accessory to the Beam Brush and allows the user to view his/her brushing usage data for the user's convenience and education. The Beam App, collection of data, and transmission of data are not intended for the diagnosis and treatment of disease or to affect the structure or function of the body. The Beam Brush's capacitive sensor and Bluetooth® radio are powered by a single AA alkaline battery that is replaceable. The Beam Brush also comprises a replaceable brush head that connects to the handle at the base of the neck.
The provided text describes the Beam Brush/Beam App, a manual toothbrush with a capacitive sensor that collects brushing usage data and transmits it wirelessly to a mobile application. However, the document does not contain a study that proves the device meets specific acceptance criteria in the way typically required for a medical device that makes diagnostic or therapeutic claims.
The device is classified as a Class I manual toothbrush (21 CFR 872.6855) with the product code EFW. Class I devices are subject to general controls and typically do not require extensive clinical studies to demonstrate safety and effectiveness in the same way Class II or Class III devices do. The primary focus of the testing mentioned in this particular submission is on establishing substantial equivalence to a predicate device (Oral-B® "sub-brand" manual toothbrush, K073224) and ensuring electrical safety, electromagnetic compatibility, and software verification/validation.
Here's an analysis based on the provided text, addressing the points where information is available:
1. Table of Acceptance Criteria and Reported Device Performance:
The document doesn't present a table of specific, quantifiable acceptance criteria for clinical performance (e.g., plaque reduction percentage) and corresponding device performance data in the context of a clinical study. Instead, the "testing" section focuses on demonstrating mechanical integrity, electrical safety, and software functionality to support substantial equivalence.
Acceptance Criteria Category | Specific Criteria (as inferred/stated) | Reported Device Performance |
---|---|---|
Mechanical Integrity | Pull-off force of brush head | Tested to demonstrate substantial equivalence to legally marketed toothbrushes for the brush head remaining connected during normal brushing. (Specific force values or pass/fail criteria are not provided.) |
Electrical Safety | Compliance with IEC 60601-1 | Will comply with applicable requirements of IEC 60601-1. This evaluation demonstrates substantial equivalence regarding electrical safety. |
Electromagnetic Compatibility (EMC) | Compliance with IEC 60601-1-2 | Will comply with applicable requirements of IEC 60601-1-2. This evaluation demonstrates substantial equivalence regarding EMC. |
Radio Frequency (RF) Compliance | Compliance with FCC Equipment Authorization | Will comply with applicable requirements of FCC Equipment Authorization. |
Software Functionality | Software Verification and Validation | Completed software verification and validation testing, demonstrating substantial equivalence when using the software application. (Specific test results or metrics are not provided.) |
2. Sample Size for Test Set and Data Provenance:
No information is provided about a specific "test set" for performance evaluation in a clinical context. The testing described focuses on engineering and regulatory compliance rather than clinical efficacy.
3. Number of Experts and Qualifications for Ground Truth:
Not applicable. The device's primary function as a manual toothbrush for plaque removal is well-established, and the data collection/transmission feature is stated to be for "convenience and education," not for diagnosis or treatment. Therefore, the concept of establishing "ground truth" by experts for clinical efficacy (e.g., disease detection) is not within the scope of this submission.
4. Adjudication Method:
Not applicable. No clinical study with expert adjudication is mentioned.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
No MRMC study was done. The device does not involve human readers interpreting data for diagnostic purposes with or without AI assistance.
6. Standalone Algorithm Performance:
The device has a "standalone" function in the sense that the sensor collects data and the app displays it, but this is not an "algorithm only" performance study in a diagnostic context. The software application is an accessory for displaying data, not a diagnostic or treatment algorithm. The Beam App is a minor level of concern software.
7. Type of Ground Truth Used:
The concept of "ground truth" (e.g., pathology, outcomes data) is not applicable in the context of this 510(k) submission. The device is a manual toothbrush, and its data collection feature is for user information, not for clinical decision-making. The ground truth for its basic function (plaque removal) is implicitly understood from the long history of manual toothbrushes.
8. Sample Size for the Training Set:
No training set is mentioned as the device does not employ machine learning or AI models that require training data for diagnostic or prognostic purposes.
9. How the Ground Truth for the Training Set Was Established:
Not applicable, as no training set is mentioned.
Summary of the Study and Device Justification:
The "study" or justification for the Beam Brush/Beam App's acceptance is based on demonstrating substantial equivalence to a legally marketed predicate manual toothbrush (Oral-B® "sub-brand" manual toothbrush, K073224). This substantial equivalence is primarily established through:
- Mechanical Testing: Demonstrating the brush head remains connected during normal use.
- Electrical Safety and EMC Testing: Compliance with international standards (IEC 60601-1 and IEC 60601-1-2) and FCC authorization for the electronic components.
- Software Verification and Validation: Ensuring the software accessory functions as intended and is of "minor level of concern."
The key takeaway is that the Beam Brush/Beam App is essentially a manual toothbrush with an added feature for collecting and displaying brushing duration data. The FDA cleared it as a Class I device based on its similarity to existing manual toothbrushes, with the data collection feature presented as an accessory for user education and convenience, explicitly not for diagnosis or treatment. Therefore, the acceptance criteria and supporting "study" are focused on regulatory compliance and basic functional safety rather than clinical efficacy against specific performance metrics for a diagnostic or therapeutic claim.

Re: K073224
Trade/Device Name: Oral-B® "sub-brand" manual toothbrush Regulation Number: 872.6855
To promote good oral hygiene including plaque removal and treating and preventing gingivitis.
The Oral-B® toothbrush is a manual toothbrush comprised of a shaft with synthetic bristles at one end. The bristles are arranged in a pattern to achieve effective mechanical plaque removal. Some of the bristle tufts have a wear indicator function. These Indicator bristles are colored with FDA approved colorant, FD&C Blue No. 2.
The provided text describes a 510(k) submission for an Oral-B® manual toothbrush, where the manufacturer is seeking to expand the indication for use to include "treating and preventing gingivitis." The core of the submission emphasizes that the device is substantially equivalent to legally marketed predicate devices, with no changes in material, design, or manufacturing process, but only an expanded indication.
However, the document does not contain specific acceptance criteria in a quantitative format (e.g., a specific percentage reduction in gingivitis or plaque). Instead, it states that numerous controlled clinical studies have been performed and "collectively, these studies demonstrate that Oral-B® manual toothbrushes are effective at treating and preventing gingivitis via the physical/mechanical removal of plaque."
Therefore, it is not possible to construct a table of acceptance criteria and reported device performance as requested, because specific quantitative metrics and thresholds for acceptance are not detailed in the provided text.
Furthermore, the document primarily functions as a 510(k) summary and the FDA's response, rather than a detailed study report. As such, many of the specific details about the studies (sample sizes, data provenance, ground truth establishment, expert qualifications, adjudication methods, MRMC studies, standalone performance, training set details) are not present in the given text.
Based on the provided information, here's what can be extracted and what is missing:
Acceptance Criteria and Reported Device Performance
As stated above, the document does not explicitly list quantitative acceptance criteria. Instead, it refers to a body of clinical evidence supporting the expanded indication. The reported "performance" is qualitative, indicating effectiveness in treating and preventing gingivitis and removing plaque.
Acceptance Criteria (Not Explicitly Stated) | Reported Device Performance (Qualitative) |
---|---|
[Specific quantitative metrics for plaque removal or gingivitis reduction are not provided in this document] | The Oral-B® manual toothbrush is "effective at treating and preventing gingivitis via the physical/mechanical removal of plaque." |
[Specific thresholds for safety endpoints are not provided] | "Safety was assessed," and the studies support the "safety and effectiveness." |
Study Details
Due to the nature of the provided document (a 510(k) summary and FDA letter), many of the specific study details are not available in the text.
-
Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- Not available in the provided text. The document states "numerous controlled clinical studies" but does not provide specific sample sizes for these studies, their design (retrospective/prospective), or their geographic origin. The bibliography lists several clinical investigations but does not offer these details in the provided snippets.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
- Not available in the provided text. This type of detail is typical for device performance studies involving interpretation, but for a manual toothbrush assessing plaque and gingivitis, the "ground truth" would likely be based on clinical measurements (e.g., Gingival Index, Plaque Index) performed by trained dental professionals rather than "experts establishing ground truth" in the diagnostic imaging sense. However, no specific details on the assessors or their qualifications are provided.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not available in the provided text. Adjudication methods are typically relevant for studies where subjective assessments by multiple readers need to be reconciled, such as in diagnostic imaging. For clinical measurements of plaque and gingivitis, standard clinical protocols for measurement and inter-examiner reliability would be more typical, but no such details are provided.
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- Not applicable. This question pertains to AI-assisted diagnostic tools. The device in question is a manual toothbrush, which is a physical device, not an AI or diagnostic software. Therefore, an MRMC study comparing human readers with and without AI assistance is not relevant to this submission.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. As above, this question is for AI/software devices. The manual toothbrush is a standalone physical device. Its performance is its intrinsic mechanical action.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Implied Clinical Measurements/Outcomes: While not explicitly stated, for plaque removal and gingivitis improvement, the ground truth would be based on clinical indices and outcomes data (e.g., Gingival Index scores, Plaque Index scores, bleeding on probing, etc.) measured by trained dental examiners.
-
The sample size for the training set:
- Not applicable. This question is typically for machine learning models. For a physical device like a toothbrush, there isn't a "training set" in the machine learning sense. The clinical studies establish its effectiveness.
-
How the ground truth for the training set was established:
- Not applicable. As above, this refers to machine learning models.
Summary of available information regarding the "study that proves the device meets the acceptance criteria":
- Device: Oral-B® "sub-brand" manual toothbrush.
- Expanded Indication: To promote good oral hygiene including plaque removal and treating and preventing gingivitis.
- Proof basis: "Numerous controlled clinical studies" have evaluated the effectiveness of the manual brush at removing plaque and improving and maintaining gingival health, and assessed soft and hard tissue safety.
- Conclusion: These studies "demonstrate that Oral-B® manual toothbrushes are effective at treating and preventing gingivitis via the physical/mechanical removal of plaque." The information "supports the safety and effectiveness" and "substantial equivalence to the predicate devices without raising any new safety and effectiveness issues."
- Underlying studies: A bibliography lists several clinical investigations conducted from 1996 to 2007, some of which compare power toothbrushes to manual toothbrushes, or compare different manual toothbrushes. These titles suggest that the studies indeed focused on efficacy in plaque removal and gingivitis reduction.
In essence, the 510(k) relies on a body of existing clinical evidence to support the expanded indication, rather than presenting a single, new, dedicated study with detailed acceptance criteria and performance metrics for this specific submission. The FDA's approval indicates they found this collective evidence sufficient to establish substantial equivalence for the expanded indication.

Re: K023662
Trade/Device Name: Prosonic™ Ultraviolet Toothbrush Sanitizer Regulation Number: 21 CFR 872.6855
The proSonic™ Ultraviolet Toothbrush Sanitizer is intended for use in reducing bacterial contamination that naturally accrues on toothbrushes under normal conditions of use.
The proSonic Ultraviolet Toothbrush Sanitizer unit sanitizes toothbrushes hung inside the unit by reducing the amount of bacteria that accrues on them under normal conditions of use. Sanitization is accomplished via ultraviolet (UV) radiation produced by a UV lamp housed within the unit. When activated, the proSonic Ultraviolet Toothbrush Sanitizer completes an initial sanitization cycle in one (1) hour. Afterwards, a built-in timer in the unit alternately causes the UV lamp to be turned off for sixty (60) minutes and turned on for five (5) minutes in between brushing cycles. Depending on usage, the UV lamp will typically be activated for approximately one hundred-sixty five (165) minutes per day. The bulb has an effective Iife of ten thousand (10,000) hours. The sanitizer is designed so that the UV lamp can be activated only when the unit door is fully closed, and the level of ozone emitted by the sanitizer is within FDA regulatory limits. The proSonic Ultraviolet Toothbrush Sanitizer is sold with four (4) accompanying toothbrushes and a power handgrip (which converts the toothbrushes into powered toothbrushes).
Here's a breakdown of the acceptance criteria and study information for the Prosonic™ Ultraviolet Toothbrush Sanitizer based on the provided document:
This document is a 510(k) premarket notification for a medical device seeking substantial equivalence to a predicate device. It primarily focuses on demonstrating that the device is "as safe, as effective, and performs as well as or better than" the predicate. Therefore, the "acceptance criteria" presented are implicitly derived from the performance of the predicate and the general safety standards for similar devices. There isn't a clearly defined set of numerical acceptance criteria like you would typically find for a more novel device performance study.
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Implicit) | Reported Device Performance (Prosonic™ Ultraviolet Toothbrush Sanitizer) |
---|---|
Bacterial Contamination Reduction: Significant reduction in bacterial contamination on toothbrushes. | "bacterial contamination on toothbrushes is significantly reduced by the device" |
Ozone Emissions: Within FDA regulatory limits (specified at 21 C.F.R. § 801.415). | "the ozone emitted by this product is minimal and within limits specified at 21 C.F.R. § 801.415 (2002)." |
Safety Feature (Door Interlock): UV lamp can only be activated when the unit door is fully closed. | "The sanitizer is designed so that the UV lamp can be activated only when the unit door is fully closed." |
Material and Design Equivalence: Substantially equivalent to the predicate device. | "Both devices are substantially equivalent in terms of materials and design." |
Technological Characteristics: Substantially equivalent to the predicate device (e.g., uses UV light, similar ozone emissions, similar UV bulb wavelengths). | "Both the proSonic and the Purebrush sanitizers use ultraviolet light to reduce bacterial contamination. ... Ozone emissions for the two devices are similar... The UV lamps in both devices cannot be activated unless the units are fully closed. The wavelengths emitted by the UV bulbs in the two devices are also substantially equivalent." |
Effective UV Lamp Life: (Predicate's effective life) | "The bulb has an effective life of ten thousand (10,000) hours." (While different from the predicate, this difference is stated to "not significant to the safety or effectiveness.") |
Sanitization Cycle Length: (Predicate's cycle length) | "completes an initial sanitization cycle in one (1) hour." (While different from the predicate, this difference is stated to "not significant to the safety or effectiveness.") |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: Not explicitly stated. The document mentions "Laboratory and actual use tests" were conducted but does not provide specific numbers of toothbrushes, test subjects, or samples examined for bacterial reduction or ozone emission.
- Data Provenance: The study was conducted for Hwadong International Company, Ltd., which is based in Korea. The document does not specify if the testing itself was performed in Korea, the US, or elsewhere, nor does it explicitly state if the data was retrospective or prospective. Given the context of a premarket notification for a new device, it is most likely prospective testing specifically performed for this submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
- Number of Experts: Not applicable/not specified. For bacterial reduction and ozone emissions, the ground truth would be based on objective laboratory measurements rather than expert consensus. No specific experts are mentioned as establishing ground truth in this context.
4. Adjudication Method for the Test Set
- Adjudication Method: Not applicable/not specified. Since the measurements are objective (bacterial counts, ozone levels), there wouldn't typically be a separate adjudication process for ground truth.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size
- MRMC Study: No, an MRMC comparative effectiveness study was not done. This type of study relates to the performance of human readers (e.g., radiologists) with and without AI assistance, which is not relevant to a physical device like a toothbrush sanitizer.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done
- Standalone Performance: Yes, in essence. The entire evaluation focuses on the performance of the device itself ("algorithm only" in a conceptual sense for a physical product) in reducing bacteria and emitting ozone, without human intervention or human-in-the-loop performance being a factor in the device's function or evaluation.
7. The Type of Ground Truth Used
- Type of Ground Truth: The ground truth for bacterial reduction would be based on microbiological assay results (i.e., direct counts of bacterial colonies from samples before and after sanitization). The ground truth for ozone emissions would be based on chemical analysis/sensor readings using established testing protocols to detect and quantify ozone levels. These are objective laboratory measurements.
8. The Sample Size for the Training Set
- Sample Size for Training Set: Not applicable/not specified. This device is a physical product, not an AI/ML algorithm that requires a "training set" in the computational sense. The "development" of the device would involve engineering and physical testing, not data training.
9. How the Ground Truth for the Training Set Was Established
- How Ground Truth for Training Set Was Established: Not applicable. See point 8.

01880
Re: K021383
Trade/Device Name: Zeodyne™ Toothbrush with AgION™ Antimicrobial Regulation Number: 872.6855
The Zeodyne Toothbrush with AgION™ Antimicrobial is intended to remove adherent plaque and food debris from the teeth. The addition of the antimicrobial agent is to prevent the growth of bacteria on the toothbrush between brushings. The antimicrobial treatment is not intended to have any effect on the user.
The Zeodyne Toothbrush with AgION antimicrobial is a manual toothbrush consisting of a shaft with synthetic bristles at one end intended to remove adherent plaque and food debris from the teeth. The toothbrush contains an antimicrobial agent to prevent the growth of bacteria on the brush between uses, maintaining the cleanliness of the brush.
The Zeodyne Toothbrush with AgION antimicrobial consists of a polymer based handle and either Nylon 6-12 or polybutylene terephthalate (PBT) bristles. The bristles contain 0.5% AgION antimicrobial.
The provided text describes a 510(k) premarket notification for a toothbrush, not an AI/ML device. Therefore, the questions related to AI/ML device performance, ground truth, expert opinions, and training/test set sample sizes are not applicable to this document.
However, I can extract information related to the device's functional performance criteria (as implied by its "antimicrobial" claim) and the study that supports it.
Here's the relevant information:
1. A table of acceptance criteria and the reported device performance
Acceptance Criteria (Implied) | Reported Device Performance |
---|---|
Prevent bacterial growth on the toothbrush between uses | Laboratory studies for plastic bristle fibers containing AgION antimicrobial have shown that the product reduces the growth of bacteria on the surface of the fiber. |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- The document mentions "Laboratory studies," but does not specify the sample size for these studies.
- The provenance is not explicitly mentioned (e.g., country of origin, retrospective/prospective). It simply states "Laboratory studies."
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not applicable as this is not an AI/ML device and the ground truth for antimicrobial efficacy is typically established through standardized microbiological tests, not expert consensus on human-interpreted data.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable. The "study" here refers to laboratory tests of the antimicrobial efficacy, not a diagnostic or interpretive task that would require adjudication.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not applicable. This is not an AI-assisted device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. This is a physical product (toothbrush) with an antimicrobial agent. Its performance is inherent to the substance, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- The ground truth for the antimicrobial efficacy is based on whether the "product reduces the growth of bacteria on the surface of the fiber," which implies microbiological laboratory measurements and potentially quantitative bacterial count reduction compared to controls. The antimicrobial agent itself is registered with the EPA as a bacteriostat, suggesting established methods for proving such claims.
8. The sample size for the training set
- Not applicable. This is not an AI/ML device.
9. How the ground truth for the training set was established
- Not applicable. This is not an AI/ML device.

DENTOSAN® Filaments
Antibacterial Toothbrush Filament
Manual Toothbrush (Class I Device Ref 21CFR 872.6855
K020776
Trade/Device Name: Medoral Hygienic Toothbrush with DENTOSAN® Filaments Regulation Number: 872.6855
The Medoral Hygienic Toothbrush with DENTOSAN® Filaments is a toothbrush to remove plaque and debris from the teeth and prevent tooth decay. The antibacterial agent impregnated in the filament kills bacteria and prevents their growth on and between the bristles after and between uses.
The Medoral Hygienic Toothbrush is a toothbrush with DENTOSAN® filaments. The DENTOSAN® filament is a nylon filament impregnated with an anti bacterial agent to prevent the growth of bacteria on and between the filaments after use of the toothbrush.
The provided text refers to a 510(k) summary for a "Medoral Hygienic Toothbrush with DENTOSAN® Filaments," a manual toothbrush with antibacterial properties. The summary describes the device, its intended use, and its technological characteristics. It also states that "The effect of the antimicrobial agent was tested and found to be effective using worst case testing for useful life, simulated use extraction testing and antimicrobial effectivity. Additionally, the filament was determined to be biocompatible using the methods recommended in ISO 10993 Biological Testing of Medical and Dental Materials and Devices."
However, the provided document does not contain detailed information about specific acceptance criteria and a study proving the device meets those criteria in the format requested.
Here's an attempt to answer the questions based only on the provided text, highlighting the missing information:
1. A table of acceptance criteria and the reported device performance
The document mentions "worst case testing for useful life, simulated use extraction testing and antimicrobial effectivity." It also states "The antimicrobial agent used is the DENTOSAN® filament does not raise any new safety or effectiveness concerns." and "The biocompatibility and effectiveness of the antibacterial agent was tested using established scientific methods and test protocols."
However, it does not provide specific numerical acceptance criteria (e.g., "bacterial reduction by X%") or the reported device performance data against those criteria.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the document.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not applicable as the device is a toothbrush, and the testing described (antimicrobial effectivity, biocompatibility) typically involves laboratory assays rather than expert interpretation of images or clinical outcomes in the usual sense of "ground truth" for medical imaging AI. Therefore, no experts would be establishing "ground truth" in this context.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not applicable as the relevant studies described are laboratory-based antimicrobial and biocompatibility tests, not studies requiring human adjudication of results.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
An MRMC study is not applicable or mentioned for this device. This type of study is relevant for diagnostic devices, particularly those involving human interpretation of medical images, where AI might assist readers. This device is a manual toothbrush.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This question is not applicable to a manual toothbrush. It refers to AI-driven algorithms.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the antimicrobial effectiveness, the "ground truth" would likely be established by quantitative measurements of bacterial reduction using standardized microbiology laboratory methods (e.g., colony forming units count).
For biocompatibility, the "ground truth" is established by validated biological assays as per ISO 10993, comparing the device's material with established safety benchmarks.
The document does not explicitly detail these "ground truth" methods but refers to "established scientific methods and test protocols" and ISO 10993.
8. The sample size for the training set
This question is not applicable to this device. A "training set" is relevant for machine learning or AI models, which are not described or implied for this manual toothbrush.
9. How the ground truth for the training set was established
This question is not applicable for the same reasons as point 8.

Trade/Device Name: Germ Terminator GT 100 Toothbrush Sanitizer Regulation Number: 872.6855
The Germ Terminator Toothbrush Sanitizer is designed to sanitize up to two manual toothbrushes or two toothbrush heads between uses. The Germ Terminator Toothbrush Sanitizer is intended for home use and will be available "over the counter."
The Germ Terminator uses steam heat to sanitize two manual toothbrushcs or two toothbrush heads. Water is poured into a reservoir in the device's housing and it is heated to its boiling point. Water is thereby converted into steam, which sanitizes the toothbrushes in the housing. The stcam cycle is followed by a drying cycle.
The provided text describes a 510(k) premarket notification for the "Germ Terminator Toothbrush Sanitizer." It details the device's function, intended use, and its substantial equivalence to a predicate device. However, it does not contain the detailed information required to fill out the requested table and answer all the questions about acceptance criteria and a study proving device performance as a medical device in the typical sense of AI/algorithm performance.
The submission is for a physical device (toothbrush sanitizer), not an AI/algorithmic medical device, which is why much of the requested information (like sample sizes for test/training sets, expert qualifications, MRMC studies, standalone performance, etc.) is not present in the document.
The document indicates "Laboratory testing demonstrated that toothbrushes treated in the Germ Terminator are effectively sanitized," but it does not provide the specifics of this testing in terms of acceptance criteria or performance metrics beyond this general statement.
Therefore, I will extract what information is available and explicitly state where the requested information is absent or not applicable to this type of device submission.
Acceptance Criteria and Device Performance
1. A table of acceptance criteria and the reported device performance
Acceptance Criteria | Reported Device Performance |
---|---|
Sanitization Efficacy | "Testing demonstrated that the toothbrushes treated in the Germ Terminator were sanitized." |
"Laboratory testing demonstrated that toothbrushes treated in the Germ Terminator are effectively sanitized." |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size for Test Set: Not specified in the provided document. The document only states "Laboratory testing."
- Data Provenance: Not specified in the provided document.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Number of Experts: Not applicable. For a physical device like a toothbrush sanitizer, "ground truth" is typically established through microbiological testing standards and results, not via expert consensus on image interpretation or diagnosis.
- Qualifications of Experts: Not applicable.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Adjudication Method: Not applicable. This concept is relevant for studies involving human interpretation or subjective assessments, not for objective laboratory testing of sanitization efficacy.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- MRMC Study: No, an MRMC comparative effectiveness study was not done. This type of study is specific to imaging devices or AI algorithms where human readers interpret data, typically in a diagnostic context. This device is a physical sanitizer.
- Effect Size: Not applicable.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Standalone Performance Study: Not applicable. This device is a physical sanitizing unit, not an algorithm. The "standalone" performance here refers to its inherent sanitization capability, which was reportedly tested in a lab.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- Type of Ground Truth: Likely microbiological test results demonstrating the reduction or elimination of specific microorganisms. The document uses the general term "sanitized" which implies a measurable reduction in microbial load to a safe level, based on established public health standards for sanitization.
8. The sample size for the training set
- Sample Size for Training Set: Not applicable. This is not an AI/ML device that requires a training set.
9. How the ground truth for the training set was established
- Ground Truth for Training Set Establishment: Not applicable. This is not an AI/ML device.

The provided text is a 510(k) summary for the Crest Toothbrush with MicroShield. It details the device's purpose, comparison to predicate devices, and regulatory approval. However, it does not contain any information about acceptance criteria or specific study results that prove the device meets these criteria.
Therefore, I cannot fulfill your request for:
- A table of acceptance criteria and the reported device performance
- Sample size used for the test set and the data provenance
- Number of experts used to establish the ground truth
- Adjudication method
- Multi-reader multi-case (MRMC) comparative effectiveness study
- Standalone performance study
- Type of ground truth used
- Sample size for the training set
- How the ground truth for the training set was established
The document focuses on demonstrating substantial equivalence to predicate devices based on technological characteristics and intended use, rather than presenting detailed performance data against predefined acceptance criteria from a study.

Device Classification | Manual Toothbrush -- Class I Device
(Ref. 21 CFR § 872.6855
REACH® Antibacterial Toothbrush is used to remove adherent plaque and food debris from teeth to reduce tooth decay. This device is made of a shaft (handle) with synthetic bristles attached at one end. An antibacterial agent has been added to the handle portion. The antibacterial activity is limited to the handle of the toothbrush.
Both the modified device and the predicate device are manual toothbrushes consisting of a shaft with synthetic bristles at one end. Antibacterial agents have been incorporated into the devices.
The acceptance criteria and study proving the device meets them are summarized below:
1. Acceptance Criteria and Reported Device Performance:
Acceptance Criteria Study | Acceptance Criteria (Implicit) | Reported Device Performance |
---|---|---|
Microbiology Study - Zone of Inhibition Test | The "plastic" portion of the toothbrush with antibacterial agent should be effective in inhibiting the growth of bacteria. | The "plastic" portion of the toothbrush with antibacterial agent added was effective in inhibiting the growth of most of the bacteria tested. |
Analytical Study - Extraction Study Using HPLC | No detectable antibacterial agent should leach out into a toothpaste/water slurry after 6 hours of simulated brushing, nor into an alcohol/water solution after 24 hours of soaking. (Limit of quantitation = 1 ppm) | HPLC results showed no detectable antibacterial agent in either the toothpaste/water slurry or the alcohol/water solution (limit of quantitation of antibacterial agent = 1 ppm). |
Mucous Membrane Irritation - Hamster Cheek | The toothbrush with added antibacterial agent should not cause a significant difference in degree of irritation compared to toothbrushes without antibacterial agent when in contact with oral mucosal tissue. | Results showed no significant difference in degree of irritation between toothbrushes with antibacterial agent and toothbrushes without antibacterial agent. |
In vitro Cytotoxicity Study - USP Agar Diffusion | No evidence of cell lysis or toxicity should be observed for the toothbrush with antibacterial agent added. | Results showed no evidence of cell lysis or toxicity for either the toothbrushes with an added antibacterial agent or the toothbrushes without an added antibacterial agent. |
2. Sample Size and Data Provenance:
- Test Set Sample Sizes:
- Microbiology Study: "several different strains of bacteria" were exposed. The exact number of strains or individual samples is not specified.
- Analytical Study: Not explicitly stated, but implies a sufficient number of samples were run for the HPLC analysis of the two solutions (toothpaste/water slurry and alcohol/water solution).
- Mucous Membrane Irritation: Implies a comparison between "toothbrushes with antibacterial agent" and "toothbrushes without antibacterial agent" in hamster cheek pouches. The specific number of hamsters or toothbrushes is not provided.
- In vitro Cytotoxicity Study: Implies a comparison between "toothbrushes with an added antibacterial agent" and "toothbrushes without an added antibacterial agent" as tested on mammalian cell cultures. The specific number of cell cultures or toothbrush samples is not provided.
- Data Provenance: Not explicitly stated, but given Johnson & Johnson Consumer Franchises Worldwide is the submitter and the reports are part of a 510(k) submission, the studies were likely conducted internally or by contract research organizations within the United States. The studies are prospective in nature, designed to evaluate the safety and performance of the modified device.
3. Number of Experts and Qualifications for Ground Truth:
- Not applicable as the reported studies are laboratory and preclinical tests, not analyses requiring expert human interpretation of medical images or data. The "ground truth" for these tests comes from the scientific methods themselves (e.g., inhibition zones, HPLC readings, irritation scores, cytotoxicity assays).
4. Adjudication Method:
- Not applicable for these types of laboratory and preclinical studies.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
- No, a multi-reader multi-case (MRMC) comparative effectiveness study was not conducted as this is a toothbrush, not a diagnostic device involving human readers of medical cases.
6. Standalone Performance Study:
- Yes, all the described studies (Microbiology Study, Analytical Study, Mucous Membrane Irritation, and In vitro Cytotoxicity Study) are standalone evaluations of the device's characteristics and performance. They assess the device itself against scientific benchmarks and comparisons to a non-antibacterial version, without human-in-the-loop performance measurement.
7. Type of Ground Truth Used:
- The ground truth used for these studies is based on objective scientific measurements and established laboratory protocols:
- Microbiology: Direct observation of bacterial growth inhibition (Zone of Inhibition).
- Analytical: Quantitative chemical analysis using High-Performance Liquid Chromatography (HPLC) to detect specific compounds.
- Mucous Membrane Irritation: Histopathological or macroscopic assessment of tissue irritation in a preclinical model.
- In vitro Cytotoxicity: Observation of cell lysis and viability in mammalian cell cultures following USP guidelines.
8. Sample Size for the Training Set:
- Not applicable. These are verification and validation studies (test sets) for a physical device, not an AI/machine learning model that requires a "training set."
9. How Ground Truth for the Training Set Was Established:
- Not applicable, as there is no training set for an AI/machine learning model in this context.
