The DEXIS CariVu 3-in-1 by KaVo acquires patient images as a diagnostic aid for detection of smooth surface caries, occlusal caries, proximal caries, secondary caries, and tooth cracks. The DEXIS Cari Vu 3-in-1 by KaVo is designed for use by a trained professional in the field of dentistry.

The device is used as an intraoral camera to acquire images in the oral cavity of the patient. The camera combines three different known applications from available intraoral cameras in one device. These applications are standard camera functionality, transillumination and fluorescence caries detection. Therefore, the camera uses different light colors for each of the three applications to illuminate the tooth. In combination with an optical system, CMOS sensor, and an internal image processing unit, a digital image of the tooth is generated. The live images are transferred as a standard mjpg video stream via USB interface to a running computer and can interface with a dental imaging software such as for example CONEXIO for basic intraoral camera management functionality.

The device may be used as an aid for monitoring caries lesion size and shape by comparing images taken with the Dexis CariVu 3-in-1 by KaVo over time, by using different reference points, such as tooth contour and position the device to optimize capturing tooth features previously recorded in a still or video image.

For easy use the camera is equipped with an autofocus mechanism which will provide a sharp representation of the tooth which is placed in the center of the imaqe. The autofocus provides the ability to have sharp images from close distances of about 2mm to about 120mm distance.

The different operation modes are described as follows:

1.) Color mode:
For normal color images, a white LED for illumination is used. With this light the camera provides coloured images or videos. The camera can be used with or without a Tip Vision Full HD which is required for illumination for the transillumination mode.

2. Fluorescence mode:
   For the fluorescence mode the blue LED illumination is used. The blue light excites bacterial porphorines as an aid to detect caries.

To enhance the image quality and to minimize external light influence on the fluorescence effect the accessories Fluorescence Cover Vision Full HD can be used optionally with the camera. The Fluorescence Cover Vision Full HD is a rubber cap which can be slipped on the front camera head and prevent or minimize external light on the images surface of the tooth. After each usaqe the Fluorescence Cover Vision Full HD will be reprocessed separately.

The camera can be used with or without a Tip Vision Full HD which is required for illumination for the transillumination mode. This mode is used to record images and videos to aid in the diagnosis of caries (mainly in the occlusal area) and plaque by means of fluorescent effect.

3. Transillumination mode (by the use of near infrared light):
   The transillumination mode provides images to aid in the detection of caries. For this mode near infrared light will be used. The near infrared light penetrates the side of the tooth near gingiva and illuminates the enamel of the tooth to produce gray scale images whereby intact enamel appears bright, and defects such as caries or cracks result in diffusion of light path and create an area of dark appearance.

To use this mode, the Tip Vision Full HD must be attached to the device as the LEDs for the illumination are located inside the Tip Vision Full HD. The Tip Vision Full HD touches the side of the tooth and gingiva and illuminates it from two sides whereas the image is taken from the top.

The DEXIS CariVu 3-in-1 by KaVo is available in two similar models. The differences between the models are a wall mounted version to store the device with a cable length of 2.5 meters (model 1.011.4444) and a table holder version to store the device on a dental unit with a cable length of 1.55 meters (model 1.013.1700). All critical components within the DEXIS CariVu 3in-1 by KaVo are common. A disposable sheath is used with the device to mitigate the potential for cross contamination.

The provided text does not contain detailed information about specific acceptance criteria or an in-depth study proving the device meets those criteria, especially in the format requested. The document is a 510(k) summary for the DEXIS CariVu 3-in-1 by KaVo, primarily focusing on demonstrating substantial equivalence to predicate devices rather than presenting the results of a primary clinical study with predefined acceptance criteria.

However, I can extract the following information from the text:

1. Table of acceptance criteria and reported device performance:

The document does not provide a table of acceptance criteria with corresponding performance metrics like sensitivity, specificity, accuracy, or AUC. It focuses on comparison of capabilities and safety standards with predicate devices.

2. Sample size used for the test set and the data provenance:

• Clinical Testing: "Clinical testing was not conducted on this product." This indicates that there was no clinical test set for performance evaluation in the context of this 510(k) submission.

3. Number of experts used to establish the ground truth for the test set and their qualifications:

• Since no clinical testing was performed, there were no experts used to establish ground truth for a test set.

4. Adjudication method for the test set:

• Since no clinical testing was performed, there was no adjudication method for a test set.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:

• No MRMC study was done, as "Clinical testing was not conducted on this product."

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

• The device description indicates it's an intraoral camera with various modes (color, fluorescence, transillumination) "as a diagnostic aid for detection." It is designed "for use by a trained professional in the field of dentistry." This implies a human-in-the-loop scenario. No standalone performance data for an algorithm alone is provided.

7. The type of ground truth used:

• Not applicable as no clinical testing was performed to establish performance metrics against a ground truth.

8. The sample size for the training set:

• The document does not mention a training set or its size, as it states clinical testing was not conducted. This implies that the device's development and evaluation for this submission did not involve a supervised learning approach requiring a distinct training set in the context of a clinical performance study.

9. How the ground truth for the training set was established:

• Not applicable as no training set is mentioned in the context of clinical performance evaluation.

Summary of what is present in the document relevant to performance and equivalence:

The document primarily focuses on non-clinical bench testing to demonstrate performance according to international standards for medical electrical equipment, sterilization, biocompatibility, risk management, and cybersecurity. These are safety and engineering performance criteria, not clinical diagnostic performance criteria.

The PROPHYflex 4 Handpiece and Accessories is a dental handpiece intended for perform supragingival and subgingival prophylaxis treatments. The prophylaxis treatments are obtained by the projection of water, air and appropriate dental prophylaxis powders, onto the treatment site. PROPHYflex 4 Handpiece and Accessories in supra-gingival configuration is intended for use in the cleaning and polishing of teeth by removal soft deposits and areas of discoloration as well as preparing teeth for fillings or veneers and cleaning fixed bands and brackets on orthodontic appliances. PROPHYflex 4 Handpiece and Accessories in subgingival configuration is indicated for the non-surgical removal of subgingival plaque in pockets up to 5 mm after initial periodontal treatment.

The PROPHYflex 4 is an air polishing device/powder jet handpiece that projects a mixture of water and air with sodium bicarbonate, calcium carbonate or fine glycine power onto tooth surfaces. The device includes the handpiece main body with adjustable spray feature, two cannulas, a wrench for installing the cannula, two interchangeable gripping sleeves, powder container with cover, a cleaning burr and nozzle pin, and a set of spare o-rings. An optional adapter and perio tip can be installed for subgingival treatments.

The powder is filled into the powder container by the user. When activated through foot control, air is pushed into the powder container, swirling the powder and pushing it through the device and out of the cannula. The spray is only mixed with the air and powder at the very tip of the cannula, providing an even and gentle cleaning effect. The amount of powder can be regulated via three different spray settings by the adjusting ring, helping the users to perform individual treatments such as subgingival biofilm removal, removal of discoloration and bacterial plaque, orthodontics, cleaning prior to fissure sealing, prosthetics, conservative and aesthetic dentistry by providing the possibility to adjust the cleaning effects to the clinical situation of the patient at hand.

The components of the PROPHYflex 4, including the powder container, is to be completely reprocessed after each use.

The three powder levels are as follows:

• Highest Level: Suitable for supragingival treatment and offers full cleaning power .
• Medium Level: Suitable for sub- and supragingival treatment and enables . gentle cleaning at a reduced powder quantity
• . Lowest Level: Helps rinsing the powder off the tooth and blowing the powder from the system after the treatment

During supraqinqival treatments (e.g. stain removal), the device doesn't touch the patient but will be placed 3 – 5 mm from the area that is to be cleaned. During subgingival treatments (biofilm management) with the perio tip, the tip is inserted into the pocket up to 5mm and angled towards the tooth.

The provided text is a 510(k) summary for a dental handpiece, the PROPHYflex 4. It focuses on demonstrating substantial equivalence to predicate devices through technological characteristic comparison and non-clinical performance testing.

Crucially, this document explicitly states: "Clinical data is not needed to characterize performance and establish substantial equivalence. The non-clinical test data characterize all performance aspects of the device based on well-established scientific and engineering principles. Clinical testing has not been conducted on this product."

Therefore, a study demonstrating the device meets acceptance criteria via clinical performance (which would involve human readers, ground truth established by experts, MRMC studies, etc.) was explicitly not performed and is not required for this type of device according to the provided FDA submission.

However, I can extract the acceptance criteria and reported performance based on the non-clinical (bench) testing, and other relevant information from the document, framing it within the context of a "study" as requested, even if it's a bench study rather than a clinical one.

Here's a breakdown based on the provided text:

Acceptance Criteria and Reported Device Performance

The acceptance criteria for the PROPHYflex 4 are implicitly defined by its ability to perform as well as, or better than, its predicate devices across various technical specifications and to comply with relevant international standards. The study proving these criteria are met consists of non-clinical bench testing.

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are essentially demonstrated equivalence or improvement over the predicate device (AIR-FLOW Handy 3.0 Plus (K151912)) and compliance with specified ISO standards.

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size: The document does not specify exact "sample sizes" in terms of number of devices tested for each bench test. These are typically covered under the manufacturer's internal quality system documentation and test protocols, which are summarized rather than detailed in a 510(k). The tests are performed on representative units of the device.
• Data Provenance: The testing was non-clinical (bench testing).
  • Country of Origin: The manufacturer is Kaltenbach & Voigt GmbH, located in Biberach, Germany. Therefore, the testing would likely have been conducted in Germany or by approved testing facilities.
  • Retrospective or Prospective: This refers to the collection of patient data, not bench testing. Bench testing is inherently prospective in its execution, demonstrating performance against specifications.

3. Number of Experts Used to Establish Ground Truth and Qualifications of Those Experts

• This question is not applicable as the study was purely non-clinical bench testing. There were no "experts" establishing a clinical "ground truth" for a test set, as no clinical test set involving human subjects was used. The "ground truth" for bench testing is derived from engineering specifications, established medical device safety and performance standards (e.g., ISO standards), and comparative performance against legally marketed predicate devices.

4. Adjudication Method for the Test Set

• This question is not applicable as there was no test set requiring human expert adjudication (e.g., image interpretation). Bench testing results are typically objectively measured against defined criteria.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

• No, an MRMC comparative effectiveness study was explicitly NOT done. The document states: "Clinical data is not needed to characterize performance and establish substantial equivalence. The non-clinical test data characterize all performance aspects of the device based on well-established scientific and engineering principles. Clinical testing has not been conducted on this product." Therefore, there is no effect size reported for human readers improving with AI vs. without AI assistance.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

• This question is not applicable in the context of a dental handpiece. The device is a physical instrument, not an AI algorithm. Its "performance" is its mechanical, fluidic, and material characteristics demonstrated through bench testing.

7. The Type of Ground Truth Used

• The "ground truth" for this device's performance validation is based on:
  • International Standards: Compliance with ISO standards (e.g., ISO 7785-1, ISO 14457, ISO 9168, ISO 10993 series, ISO 20608).
  • Predicate Device Performance: Demonstrating that the PROPHYflex 4's performance characteristics (dimensions, noise, pressure, flow, etc.) are comparable to or improved over the legally marketed predicate device (AIR-FLOW Handy 3.0 Plus (K151912)) and other reference devices.
  • Engineering Specifications: Internal design specifications and performance targets set by the manufacturer for the device.

8. The Sample Size for the Training Set

• This question is not applicable as this is a physical medical device, not an AI/ML algorithm that requires a "training set" of data.

9. How the Ground Truth for the Training Set Was Established

• This question is not applicable as this is a physical medical device, not an AI/ML algorithm; therefore, there is no "training set" or "ground truth" establishment for it in this context.

The SMARTmatic handpieces are intended for the removal of carious material, reducing of hard tooth structure, cavity and crown preparations, root canal preparations, removal of fillings, processing and finishing tooth preparations, restorations, and for polishing teeth. They are designed for use by a trained professional in the field of general dentistry.

The SMARTmatic electrical-driven handpieces listed in the table below are dental handpieces for the use by a trained professional in the field of general dentistry. The devices are electricalpowered handpieces that are reusable and ergonomically shaped. The devices can be sterilized by the steam autoclave method. Through the tube and the electrical motor connected to a dental unit, the SMARTmatic handpieces equipped with a handpiece connection according to ISO 3964 (Dentistry - Coupling dimensions for handpiece connectors - ISO 3964:1982) receive the energy for the gear, the cooling water and air for cutting treatment. Dental burs and other attachments will be used with the SMARTmatic handpieces per ISO 1797-1:2011 (Dentistry - Shanks for rotary instruments - Part 1: Shanks made of metals).

The request asks for a detailed description of acceptance criteria and the study proving the device meets these criteria. However, the provided document is a 510(k) premarket notification for a dental handpiece (SMARTmatic), which focuses on demonstrating substantial equivalence to a predicate device rather than on specific acceptance criteria and a detailed study proving performance against those criteria.

The document primarily highlights the substantial equivalence of the SMARTmatic handpieces to the MASTERmatic LUX handpieces (K143465) based on intended use, technological characteristics, and performance data. It relies on conformance to various ISO standards and a guiding document for dental handpieces. The document does not contain information on:

• A specific table of acceptance criteria with reported device performance against numerical targets.
• Sample sizes for a test set or data provenance (as it's not a clinical study on diagnostic accuracy).
• Number of experts, their qualifications, or adjudication methods for ground truth.
• Multi-reader multi-case (MRMC) comparative effectiveness studies.
• Standalone algorithm performance (as it's a mechanical device, not an AI algorithm).
• Sample size for a training set or how ground truth for a training set was established.

Therefore, many of the requested points cannot be extracted from this document as they are not relevant to a 510(k) submission for a dental handpiece.

However, I can extract information related to the performance data and "acceptance" from the perspective of substantial equivalence and adherence to recognized standards.

Here's the information that can be extracted and a clear indication of what is not present:

1. A table of acceptance criteria and the reported device performance

The document doesn't provide a table of acceptance criteria in the sense of specific numerical thresholds for performance metrics. Instead, it relies on conformance to international standards. The "Summary of the Technological Characteristics" table ([page 7] and [page 8]) compares the new device (SMARTmatic) to the predicate device (MASTERmatic LUX) across various design and technical specifications. The "acceptance criteria" here are effectively that the new device's characteristics are either the same as the predicate or, if different, that these differences do not raise new questions of safety or effectiveness, as demonstrated by non-clinical testing to relevant standards.

Summary of Technological Characteristics and Performance (as presented in the document):

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• None stated directly. The document refers to "Performance bench testing according to international standards." This typically involves testing a defined number of device units or components, but the specific sample sizes are not provided in this summary.
• Data Provenance: Not explicitly stated, but the manufacturer is Kaltenbach & Voigt GmbH, based in Biberach, Germany. The tests are "Non-Clinical Test Data," indicating lab/bench testing, not data from human subjects. This would be considered prospective bench testing.

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. This information is for clinical studies or AI algorithm validation, not for a mechanical dental handpiece undergoing bench testing for substantial equivalence.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable. This is for clinical studies/AI algorithm validation.

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 device is a mechanical dental handpiece, not an AI-assisted diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

• Not applicable. This is a mechanical device, not an algorithm. Bench testing was done for the device itself.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

• For biocompatibility: Conformance to ISO 10993-1. The "ground truth" is that the materials used meet the specified biocompatibility standards.
• For mechanical performance (e.g., bur retention force, speed range, coupling dimensions): Conformance to relevant ISO standards (e.g., ISO 14457, ISO 1797-1, ISO 3964). The "ground truth" is whether the physical measurements and operational parameters of the device meet the requirements of these standards.
• For sterilization: Conformance to ISO 17665-1 and AAMI ANSI ST79. The "ground truth" is that the sterilization process specified for the device achieves the required sterility assurance levels.

8. The sample size for the training set

• Not applicable. This refers to AI/machine learning models.

9. How the ground truth for the training set was established

• Not applicable. This refers to AI/machine learning models.

Summary of the Study (as described in the document):

The "study" described is a non-clinical performance bench testing program to demonstrate substantial equivalence to a legally marketed predicate device (MASTERmatic LUX K143465).

• Methodology: Performance bench testing according to international standards (listed below) and biocompatibility and sterilization studies.
• Standards utilized for performance verification:
  • ISO 3964 (Dentistry - Coupling dimensions for handpiece connectors)
  • ISO 1797-1 (Dentistry - Shanks for rotary instruments - Part 1: Shanks made of metals)
  • ISO 7405 / ISO 10993-1 (Dentistry - Evaluation of biocompatibility of medical devices used in dentistry / Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management system)
  • ISO 14457 (Dentistry - Handpieces and motors)
  • ISO 17665-1 (Sterilization of health care products - Moist heat - Part 1)
  • AAMI ANSI ST79 (Comprehensive Guide To Steam Sterilization And Sterility Assurance In Health Care Facilities)
  • Guidance for Industry and FDA Staff - Dental Handpieces - Premarket Notification [510(k)] Submissions.
• Conclusion: The tests demonstrated that despite some differences in technological characteristics (e.g., external vs. internal spray, presence/absence of fiber optics, speed range, specific chuck types, and minor dimensions), these differences do not raise new concerns regarding substantial equivalence to the predicate device. The SMARTmatic handpieces are deemed substantially equivalent based on intended use, indications, technological characteristics, principle of operation, features, and performance data derived from these non-clinical tests.
• Clinical Data: The document explicitly states: "Clinical data is not needed to characterize performance and establish substantial equivalence. The non-clinical test data characterize all performance aspects of the device based on well-established scientific and engineering principles. Clinical testing has not been conducted on this product."

The provided document is a 510(k) premarket notification for a dental surgical system. It focuses on demonstrating substantial equivalence to predicate devices rather than proving specific performance metrics against acceptance criteria in the context of a new, quantifiable medical AI device evaluation. Therefore, much of the requested information (such as sample sizes for test/training sets, number/qualifications of experts, adjudication methods, MRMC studies, effect sizes, specific ground truth types, etc.) is not applicable or available in this type of submission.

The document describes non-clinical testing performed to show conformance to standards and software validation, but it does not present a study designed to establish device performance against predefined acceptance criteria in the way one would for a diagnostic or AI-driven system.

However, I can extract information related to the device's characteristics and the non-clinical tests performed.

Here's a summary of the available information based on your request:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly present a table of "acceptance criteria" and "reported device performance" in the sense of quantifiable metrics for diagnostic accuracy or clinical outcomes. Instead, it demonstrates compliance with international standards and describes functional principles and technical characteristics that are deemed substantially equivalent to predicate devices.

The "performance" is implicitly demonstrated through conformance to established standards and validation of software functionality, rather than through meeting specific numerical thresholds for a novel diagnostic claim.

2. Sample size used for the test set and the data provenance

• Sample Size for Test Set: Not applicable. The submission describes non-clinical engineering and bench testing (electrical safety, EMC, biocompatibility, software validation), not a clinical study with a "test set" of patients or data in the typical sense of evaluating diagnostic performance.
• Data Provenance: The tests described are engineering and laboratory tests, not clinical data from patients. Therefore, information like "country of origin of data" and "retrospective or prospective" is not relevant.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. There is no mention of "ground truth" or expert review in the context of establishing performance for a diagnostic or AI system. The "ground truth" for non-clinical tests would be the specifications and requirements of the relevant international standards.

4. Adjudication method for the test set

Not applicable, as there is no human review of a "test set" to establish ground truth.

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-driven or diagnostic device that involves human readers interpreting cases.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is a dental surgical system, not an algorithm or AI device. The software validation confirms the functional performance of the device's control unit, not an independent algorithm's diagnostic accuracy.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Not applicable. For non-clinical tests, "ground truth" would be the defined specifications and parameters of the standards (e.g., a certain voltage, current, or biocompatibility threshold).

8. The sample size for the training set

Not applicable. This is not an AI/machine learning device that involves a training set.

9. How the ground truth for the training set was established

Not applicable. There is no training set.

Therefore, most of the requested information regarding clinical study design, sample sizes, expert involvement, and ground truth establishment from clinical data is not present and not required for this type of regulatory submission. The "study" mentioned for acceptance is implicitly the non-clinical performance testing against international standards for dental air-driven handpieces.

Ask a specific question about this device

The DIAGNOcam 2170 Is a diagnostic ald for the detection of open or includent carles lesions above the gingiva and for monitoring the progress of such lesions.

Indications:

• Detection of smooth surface caries
• Detection of occlusal carries
• Detection of proximal carles
• Detection of Initial caries
• Detection of secondary caries
• Detection of cracks

The DIAGNOcam 2170 is a handheld laser fluorescence caries detection device which uses the DIFOTI technology (Digital Imaging Fiberoptic Transillumination) as the functional principle. KaVo DIAGNOcam 2170 delivers images, which are reminiscent of X-rays but which are completely radiation free - by means of a light that is especially adapted to this examination method. The tooth structures allow the passage of light from the entry site to the camera. Areas that block light transmission (e.g. carious lesions) show up clearly as well delimited, dark areas. A digital camera captures the actual situation and makes it visible in real-time on the screen. The USB connector provides electric power to the unit. The DIAGNOcam 2170 will be delivered with a firmware (unit) at the handheld device which is responsible for steering of the camera functions and a computer based software (image) which is responsible to show / display the pictures, store / save the pictures and the possibility of a life stream. The internal laser diode generates an exact wavelength being detectable by the CCD sensor. The DIAGNOcam 2170 follows the international standards for electrical safety and electromagnetic compatibility which are applicable for the use with human beings. The DIAGNOcam 2170 works with a laser wavelength at 788 nm and an output power of 2mW for each laser diode (2 sources). The maximum output power is 21mW/cm2.

Here's an analysis of the provided text regarding the DIAGNOcam 2170, focusing on acceptance criteria and study details:

Overall Conclusion: The provided document does not contain any acceptance criteria or a study proving the device meets them. It is a 510(k) summary, which focuses on demonstrating substantial equivalence to predicate devices, rather than presenting de novo performance studies against pre-defined acceptance criteria.

The document explicitly states: "Clinical testing has not been conducted on this product."

Therefore, I cannot populate the table or provide answers to most of your specific questions as the relevant information is not present in the provided text.

Here's how I can address the prompts based on the available information:

1. Table of Acceptance Criteria and Reported Device Performance

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 applicable, as no clinical test data is presented.
• Data Provenance: Not applicable.

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 no clinical test data is presented.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable, as no clinical test data is presented.

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

• No MRMC comparative effectiveness study was done. The document explicitly states: "Clinical testing has not been conducted on this product." The device is a diagnostic aid, not an AI system.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

• This question is largely not applicable in the context of this device. The DIAGNOcam 2170 is a hardware device (laser fluorescence caries detection device) that produces images for a dentist to interpret in real-time or from stored images. It's not an "algorithm only" device in the sense of AI performing a diagnosis without human input.
• However, the document mentions "the DIAGNOcam 2170 software has been successfully validated to confirm the performance of the device." This software handles camera functions, image display, storage, and live streaming. This validation is likely focused on the software's functional correctness rather than its diagnostic performance in a standalone capacity for caries detection.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

• Not applicable, as no clinical test data or ground truth establishment for diagnostic performance is presented.

8. The sample size for the training set

• Not applicable, as no machine learning or AI training is discussed. The device operates on the physical principle of transillumination for caries detection, not through a trained AI model.

9. How the ground truth for the training set was established

• Not applicable, as no machine learning or AI training is discussed.

The ELECTROtorque TLC 4893 is intended to convert pneumatic output from a dental treatment center to electrical energy to drive the INTRAmatic KL 702 motor for operation of electricallydriven dental handpieces. These devices are designed for use by a trained professional in the field of general dentistry.

The ELECTROtorque TLC 4893 dental control unit is a stand-alone system for operating electrically-driven KaVo handpieces. External power supply provides electric power to the unit. The 4-hole tubing connected to the unit supplies chip /cooling air, water and pressure signal. The speed of the electric handpiece is controlled by air pressure. The control unit is positioned close a treatment unit at the location preferred by the dentist. The ELECTROtorque TLC 4893 system consists of a base unit with a motor hose, an electrical motor, a transformer, and a power cord. The ELECTROtorque TLC 4893 dental control unit is a software-driven device. The software controls the following features: (1) Motor control, (2) Motor start / stop behavior, (3) Motor speed, (4) Motor performance, (5) Measuring power consumption, (6) Monitoring power consumption, and (7) SAFEdrive. The new SAFEdrive software feature monitors the power consumption of electrical hand pieces to reduce the probability or severity of overheating, thus minimizing the risk of burns to the patient. The user can navigate through the software menu via the control panel (see Figure 2.0).

The INTRAmatic KL 702 motor is an electrical low-voltage motor for dental purposes according to ISO 11498 type 2. The motor connects onto the KaVo specific tubing of the dental treatment unit ELECTROtorque. The speed of the INTRAmatic KL 702 is controlled by air pressure of the dental treatment center. The converted pneumatic output signal (electrical energy) from a dental treatment center drives the motor to operate an electrically-driven dental handpiece. Electricallydriven dental handpiece, which conform to ISO 3964, can be attached on the motor. The INTRAmatic KL 702 is intended only for dental treatment by a dental professional.

The provided text describes a medical device, the ELECTROtorque TLC 4893 with INTRAmatic KL 702, which are dental handpieces and accessories. It details the device's function, its similarities and differences to predicate devices, and the non-clinical tests performed. It explicitly states that "Clinical testing has not been conducted on these products."

Therefore, I cannot provide information on acceptance criteria or a study proving the device meets those criteria from the given text, as no clinical studies were performed. The document focuses on demonstrating substantial equivalence to legally marketed predicate devices through non-clinical testing and functional similarity.

However, I can extract the information provided about the non-clinical testing that was performed:

Non-Clinical Test Data (Acceptance Criteria and Study Details)

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• The document does not specify the sample size for any of the non-clinical tests.
• Data provenance is not explicitly mentioned (e.g., country of origin, retrospective/prospective). The tests were likely conducted internally or by a contracted lab.

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 no clinical studies or human expert ground truth establishment for software validation are detailed in the provided text. The "ground truth" for the non-clinical tests would be defined by engineering specifications, regulatory standards, or predetermined performance parameters.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable; no adjudication method for a test set is mentioned for these non-clinical tests.

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; no clinical studies, and therefore no MRMC studies, were conducted. The device (ELECTROtorque TLC 4893) includes a software feature (SAFEdrive) but is not described as an "AI" system in the context of improving human reader performance.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

• The SAFEdrive software function was validated. This would be a standalone evaluation of the algorithm's performance in monitoring power consumption and detecting overheating. The text states: "The software validation included testing of the new SAFEdrive software function to demonstrate that with this added function, the ELECTROtorque TLC 4893 is capable of detective electrical handpieces to reduce the probability or severity of overheating, thus minimizing the risk of burns to the patient." This implies an algorithm-only performance assessment against predefined overheating conditions.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

• For the SAFEdrive software validation, the ground truth would likely be established through engineered scenarios simulating various power consumption and overheating conditions. This would involve specific temperature and energy parameters as mentioned ("Temperature and energy studies have been conducted to determine the parameters for the new SAFEdrive software function").
• For electromagnetic compatibility, electrical safety, sterilization, and biocompatibility, the ground truth is established by adherence to applicable recognized consensus standards.

8. The sample size for the training set

• Not applicable; this device is not described as involving a machine learning/AI model that requires a training set in the context of the provided text. The software validation is for a rule-based or algorithmic function.

9. How the ground truth for the training set was established

• Not applicable for the same reasons as point 8.
