The provided document is a 510(k) premarket notification for dental handpiece cleaners and lubricants. As such, it focuses on demonstrating substantial equivalence to a predicate device rather than establishing new acceptance criteria and proving performance against them in the same way a de novo device might.
Here's an analysis based on the document, addressing the requested points where applicable:
1. Table of Acceptance Criteria and Reported Device Performance:
The document doesn't define specific quantitative "acceptance criteria" in the traditional sense for a new device's performance benchmarks. Instead, it relies on demonstrating that the subject devices perform comparably to a legally marketed predicate device. The "acceptance criteria" are implicitly that the subject device's performance in the specified tests is equivalent to or better than the predicate device's performance, allowing it to meet its design performance requirements.
Comparison | Test | Method | Implicit Acceptance Criteria | Reported Device Performance |
---|---|---|---|---|
Spray & Clean Handpiece Cleaner & Lubricant vs. NSK Pana Spray | Handpiece Performance Testing | Cycle ( unspecified number of cycles) | ||
Bur extraction force, | ||||
concentricity, | ||||
noise level, and torque | Performance characteristics (bur extraction force, concentricity, noise level, torque) are comparable to the predicate. | "Met handpiece performance specification" (implies equivalence to predicate) | ||
Maxima Handpiece Lubricant vs. NSK Pana Spray | Handpiece Performance Testing | Cycle (unspecified number of cycles) | ||
Bur extraction force, | ||||
concentricity, | ||||
noise level, and torque | Performance characteristics (bur extraction force, concentricity, noise level, torque) are comparable to the predicate. | "Met handpiece performance specification" (implies equivalence to predicate) |
2. Sample Size Used for the Test Set and Data Provenance:
The document does not specify the sample size used for the test set (i.e., the number of handpieces or test iterations). It simply states that "performance testing... was conducted on the subject devices and the predicate device."
The data provenance is not explicitly stated regarding country of origin or whether it was retrospective or prospective. Given the nature of a 510(k) for a device like this, it is likely that the testing was conducted prospectively by the manufacturer or a contracted lab.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts:
This type of information is generally not relevant for 510(k) submissions of accessories like handpiece lubricants. The "ground truth" here is objective physical and mechanical measurements of handpiece performance, not subjective expert assessment of clinical outcomes or images. Therefore, no experts were used in this capacity.
4. Adjudication Method for the Test Set:
Not applicable, as the "ground truth" is based on objective measurements, not expert consensus requiring adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:
No, an MRMC comparative effectiveness study was not done. This type of study is typically performed for diagnostic or AI-assisted interpretation devices where human reader performance is a key metric. This device is a maintenance product for dental equipment.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done:
Not applicable. This device is not an algorithm or an AI system. It is a physical product (lubricant). Performance is evaluated based on its effect on the mechanical function of dental handpieces.
7. The Type of Ground Truth Used:
The ground truth for the non-clinical testing was based on objective physical and mechanical measurements. Specifically, the test evaluated:
- Bur extraction force
- Concentricity
- Noise level
- Torque
These are measurable performance specifications for dental handpieces, which are expected to be maintained or improved by the lubricants.
8. The Sample Size for the Training Set:
Not applicable. This device is not an AI/ML algorithm that requires a "training set."
9. How the Ground Truth for the Training Set Was Established:
Not applicable, as there is no training set for this type of device.

This HHC-Push button air turbine is intended for use with the Midwest Tradition Handpiece in replacement of Midwest Tradition's original turbine.
The Dental Handpiece with the HHC- replacement turbine is used by authorized persons in the practice of dentistry.
The HHC-replacement turbine is used in the Midwest Tradition High Speed Dental Handpiece, which is intended for removing carious material, cavity preparations, finishing tooth preparations, reducing hard tooth structures, restorations and polishing teeth.
The HHC-Push button air turbine is a complete air turbine which will be offered as replacement turbine for Midwest Tradition original turbine.
High pressured air directly impacts the blade pockets of the impeller through an air intake tube located inside the handpiece body, which causes the air turbine to rotate at a high speed. The dental cutting bur connects to the turbine's shank (spindle), which rotates at the same speed as the impeller. Cooling water flows through an inlet water tube at high pressure and blows out at an angle near the dental cutting bur to reduce temperature at cutting area.

HANDPIECE HEADQUARTERS
The Straight Attachment and Contra Angle Sheath attachments are used with a Low Speed Dental Handpiece that is intended for removing carious material, cavity and crown preparations, finishing tooth preparations, reducing hard tooth structures, restorations and polishing teeth. These attachments are used by authorized persons in the practice of dentistry.
The Straight Attachment or the Contra Angle sheath is used to connect between the low-speed air-driven motor and the handpiece head. (1 to 1)
This 510(k) submission (K092053) for the Henry Schein Maxima-M Straight Attachment & Contra Angle Sheath does not contain a study or detailed acceptance criteria for device performance.
Instead, it relies on demonstrating substantial equivalence to predicate devices. This means that the device is considered safe and effective because it is similar in design, materials, and intended use to devices already on the market. In such cases, a detailed performance study with specific acceptance criteria is typically not required, as the safety and effectiveness are established through comparison rather than de novo testing.
Here's a breakdown based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance:
Acceptance Criteria | Reported Device Performance |
---|---|
No specific quantitative acceptance criteria are provided in this submission. The basis for acceptance is substantial equivalence to predicate devices. | The device is deemed "as safe and effective as the predicate devices" based on the comparison presented. No quantifiable performance metrics are listed. |
2. Sample Size Used for the Test Set and Data Provenance:
- Not applicable. There is no mention of a "test set" in the context of a performance study for this device. The submission focuses on a comparison to predicate devices, not on direct performance testing of the new device.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
- Not applicable. As no performance study with a test set generating new data was conducted, there were no experts establishing ground truth for such a set.
4. Adjudication Method for the Test Set:
- Not applicable. No test set or associated adjudication was performed.
5. Multi Reader Multi Case (MRMC) Comparative Effectiveness Study:
- No. The document does not describe an MRMC study. The comparison is made at a device level (similarity of design, materials, intended use) rather than assessing human reader performance.
6. Standalone (Algorithm Only) Performance Study:
- Not applicable. This device is a mechanical dental attachment; therefore, an "algorithm only" performance study is irrelevant.
7. Type of Ground Truth Used:
- Not applicable/Implicit. The "ground truth" in this context is the regulatory acceptance and established safety/effectiveness of the predicate devices. The new device leverages this existing regulatory record by demonstrating its similarity.
8. Sample Size for the Training Set:
- Not applicable. This is a hardware device; machine learning or AI models with training sets are not involved.
9. How Ground Truth for the Training Set Was Established:
- Not applicable. As above, no training set or associated ground truth establishment process is relevant for this type of device.
Summary of the Study (or lack thereof):
The "study" in this 510(k) submission is a comparison to predicate devices (MIDWEST STRAIGHT ATTACHMENT-K792445 and NSK CONTRA ANGLE SHEATH-K962540). The applicant, Handpiece Headquarters, asserts that the Henry Schein Maxima-M Straight Attachment & Contra Angle Sheath is substantially equivalent to these legally marketed devices based on:
- Device Description: Both the proposed device and the predicate devices are described as connecting between a low-speed air-driven motor and a handpiece head (1 to 1 ratio).
- Intended Use: The intended use statement for the Henry Schein Maxima-M Straight Attachment & Contra Angle Sheath is identical in function to what would be expected of the predicate devices: "removing carious material, cavity and crown preparations, finishing tooth preparations, reducing hard tooth structures, restorations and polishing teeth."
- Safety and Effectiveness: The conclusion explicitly states: "The Straight Attachment & Contra Angle Sheath are as safe and effective as the predicate devices as cited above."
The FDA's letter (Page 3 of the document) confirms that the FDA "reviewed your Section 510(k) premarket notification of intent to market the device... and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices..." This determination signifies that the FDA accepted the applicant's argument of substantial equivalence, meaning no new clinical or performance studies were required for this specific filing.

HANDPIECE HEADQUARTERS INC. - HPR INC.
The Dental Handpiece is used by authorized persons in the practice of dentistry.
This Handpiece is intended for removing carious material, cavity preparations, finishing tooth preparations, reducing hard tooth structures, restorations and polishing teeth.
The canister handpiece is a complete dental handpiece that includes the turbine (push button & a screw type). The handpiece is fully functional and is being offered in a 4 hole version.
High pressured air directly impacts the blade pockets of the impeller through an air intake tube located inside the handpiece body, which causes the air turbine to rotate at a high speed. The dental cutting bur connects to the turbine's sharik (spindle), which rotates at the same speed as the impeller. Cooling water flows through an inlet water tube at high pressure and blows out at an angle near the dental cutting bur to reduce temperature at cutting area.
This document is a 510(k) summary for the Henry Schein/HHC/SCORE Canister Handpiece, indicating a premarket notification for a dental device. The primary finding is that the device is "substantially equivalent" to a predicate device. This type of submission relies on demonstrating equivalence rather than conducting new clinical studies with established acceptance criteria and detailed performance reporting.
Therefore, the information typically found in a study proving a device meets acceptance criteria (like detailed performance metrics, sample sizes, ground truth establishment, MRMC studies, etc.) is not present in this document.
Here's an analysis based on the provided text, highlighting the absence of the requested clinical study data:
1. Table of Acceptance Criteria and Reported Device Performance
Not applicable/Not provided.
The document states: "The canister handpiece is as safe and effective as the predicate device as cited above." This is a statement of substantial equivalence, not a report of specific performance metrics against pre-defined acceptance criteria from a clinical study. No specific quantitative or qualitative acceptance criteria are listed, and no detailed performance data (e.g., accuracy, precision, durability, success rates) are reported.
2. Sample Size Used for the Test Set and Data Provenance
Not applicable/Not provided.
Since no new clinical study demonstrating performance against acceptance criteria was conducted or reported, there is no test set sample size or data provenance information. The basis for equivalence is a comparison of design and functional principles with existing predicate devices.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Not applicable/Not provided.
No test set requiring expert ground truth establishment is mentioned.
4. Adjudication Method for the Test Set
Not applicable/Not provided.
No test set requiring adjudication is mentioned.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
Not applicable/Not provided.
No MRMC study was conducted or reported. The document focuses on device design and intended use equivalence, not on human reader performance with or without AI assistance.
6. Standalone (Algorithm Only) Performance Study
Not applicable/Not provided.
This device is a mechanical dental handpiece, not an AI algorithm. Therefore, a standalone performance study in the context of an algorithm is irrelevant.
7. Type of Ground Truth Used
Not applicable/Not provided.
There is no "ground truth" mentioned in the context of a clinical performance study. The ground truth for this submission is the established safety and effectiveness of the predicate devices.
8. Sample Size for the Training Set
Not applicable/Not provided.
No training set is mentioned as this is a physical device, not a machine learning model.
9. How the Ground Truth for the Training Set Was Established
Not applicable/Not provided.
As there is no training set for an algorithm, this question is not relevant.
Summary of Device Rationale from the Document:
The basis for market clearance for the Henry Schein Canister Handpiece is substantial equivalence to an already legally marketed predicate device (SUPER-AIR S & SUPER-AIR U Handpiece Models manufactured by PENG LIM ENTERPRISE CO., Ltd.).
The document describes the device and its intended use, then states: "The canister handpiece is as safe and effective as the predicate device as cited above." This implies that by being similar in design, function, and intended use to a device already deemed safe and effective, no new, extensive clinical studies demonstrating specific performance against novel acceptance criteria were required for this 510(k) submission.
The "study" in this context is the comparison against the predicate device, not a clinical trial.
