Device Description

The Waterlase MD Turbo Plus is a dental laser device indicated for incision, excision, removal, and specific dental therapies, such as root canal therapy and periodontal therapy. All indications for use submitted for the Waterlase® MD Turbo Plus have been previously cleared by the FDA and there are no new indications included for this device.

AI/ML Overview

This K101658 510(k) submission for the Waterlase MD Turbo Plus does not contain specific acceptance criteria or a detailed clinical study demonstrating the device's performance against such criteria. Instead, it relies on substantial equivalence to previously cleared predicate devices.

Here's a breakdown based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not specify quantitative acceptance criteria or report device performance in a formal table with metrics like sensitivity, specificity, accuracy, etc. The "performance" described is largely qualitative and comparative to predicate devices.

Acceptance Criteria (Not explicitly stated as numeric targets)Reported Device Performance (as described in the "Discussion")
Equivalency for higher energy per pulse (600 mJ)Equivalent to Waterlase® MD Turbo (predicate K090181) at 600 mJ per pulse for preparation of Class II cavities
Equivalency for higher energy per pulse (600 mJ) to other predicatesEquivalent to predicate devices cleared under K030146 and K070355 for 600 mJ per pulse
Safety and Effectiveness for additional pulse frequencies (75 and 100 Hz)Determined safe and effective through performance data for gingivoplasty on pig jaw gingiva at 75 and 100 Hz, demonstrating equivalency to cleared indication for predicate devices.

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

  • Test Set Sample Size: Not explicitly stated. For the higher energy per pulse, it mentions "comparison of class II cavity preparations prepared at 600 mJ per pulse." For the new frequencies, it mentions "Gingivoplasties performed at the two new frequencies on pig jaw gingiva." No specific numbers of preparations or gingivoplasties are provided.
  • Data Provenance: The document does not specify the country of origin. The test for gingivoplasty was performed on "pig jaw gingiva," indicating an in vitro or ex vivo animal model rather than human clinical data. The comparison of Class II cavity preparations suggests an in vitro or ex vivo setting as well, given the lack of clinical study details. The data is likely retrospective in the sense that it's a comparison to established performance of predicate devices, or bench/laboratory for the specific tests mentioned.

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

  • Number of Experts: Not mentioned.
  • Qualifications of Experts: Not mentioned.

4. Adjudication Method for the Test Set:

  • Adjudication Method: Not mentioned.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

No, an MRMC comparative effectiveness study was not performed. The submission explicitly states: "No clinical performance data is required for this submission." The equivalency is established through comparison to predicate devices and limited performance data (Class II cavity preparations and gingivoplasties on pig jaw gingiva), not through human reader studies.

6. Standalone (i.e., algorithm only without human-in-the-loop performance) Study:

The Waterlase MD Turbo Plus is a physical dental laser device, not an algorithm. Therefore, a "standalone algorithm performance" study is not applicable. The performance data mentioned (cavity preparations, gingivoplasties) represents the device's direct physical interaction with tissue.

7. Type of Ground Truth Used:

  • For the Class II cavity preparations, the "ground truth" implicitly refers to the established effectiveness and safety of the predicate device (Waterlase® MD Turbo) for this application. The new device's performance is compared to this established benchmark.
  • For the gingivoplasties on pig jaw gingiva, the "ground truth" would be the observed clinical effect (e.g., successful tissue removal, absence of adverse effects) as assessed by technical or dental experts, compared to the expected outcome from predicate devices for a similar indication. This is a technical assessment rather than a diagnostic "ground truth" like pathology or clinical outcomes in a human patient.

8. Sample Size for the Training Set:

This is irrelevant as the Waterlase MD Turbo Plus is a physical device and not an AI/ML algorithm that requires a training set.

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

This is irrelevant as the Waterlase MD Turbo Plus is a physical device and not an AI/ML algorithm.
