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.

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.

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.

The PulseMaster Erbium Dental laser System is intended for the removal of caries and cavity preparation for primary and secondary teeth, the modification and etching of enamel and dentin prior to acid etching, and the incision, excision, ablation, vaporization, and coagulation of soft tissue in oral and maxillofacial surgery including, but not limited to, gingival tissues.

The PulseMaster Erbium Dental Laser System is a solid state Er.YAG laser consisting of three internally connected subassemblies: the power supply, the water cooling system, and the Er. YAG pump cavity and resonator assembly. Delivery is via a fiber optic with a sapphire contact tip. The laser delivers up to 400 mJ per pulse, with pulse repetition rates ranging from 10 to 60 Hz and an average power of up to 7.5 Watts.

The provided text is a 510(k) Summary for a medical device called the "PulseMaster Erbium Dental Laser System." This type of document is for demonstrating substantial equivalence to a predicate device, not for proving a device meets specific acceptance criteria through a study with detailed performance metrics. As such, most of the requested information regarding acceptance criteria, study design, and performance metrics is not available in the given text.

Here's a breakdown of what can and cannot be answered based on the provided document:

Acceptance Criteria and Device Performance

• No specific acceptance criteria in terms of quantitative performance metrics (e.g., sensitivity, specificity, accuracy) are reported. This document focuses on demonstrating substantial equivalence to legally marketed predicate devices primarily based on intended use, technical specifications, and mechanism of action, rather than a clinical trial with performance targets.

Study Information

1. Sample size used for the test set and the data provenance: Not applicable. No test set or clinical study to evaluate specific performance metrics is described in this 510(k) summary. The basis for substantial equivalence is a comparison to predicate devices, not a new clinical study with a test set.
2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No test set requiring ground truth establishment by experts is described.
3. Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable.
4. 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 document describes a dental laser system, not an AI-assisted diagnostic or therapeutic device.
5. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an algorithmic device.
6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable.
7. The sample size for the training set: Not applicable. This is a hardware device, not a machine learning algorithm requiring a training set.
8. How the ground truth for the training set was established: Not applicable.
