The OpusDuo EC is a model of the Opus 20 Dental Laser System, which is intended to aid during dental procedures performed either in hard or soft oral tissue. This is a dual laser system incorporating an Er:YAG laser and a CO2 laser. The system is operating at a wavelength of 2.94 microns and 10.6 microns respectively. The Er: YAG laser delivers to the tissue pulses with energies up to 1 joule per pulse and power up to 12 Watts. The CO2 laser delivers to the tissue power in continuous mode (CW) up to 10 Watts and pulses (SP) up to 6 Watts.

The provided text is a 510(k) Summary for the OpusDuo EC Dental Laser System, which focuses on demonstrating substantial equivalence to predicate devices rather than presenting a study with specific acceptance criteria and detailed performance metrics. As such, it does not contain the information required to populate a table of acceptance criteria and reported device performance directly from a study.

The document primarily relies on comparing the device's technical characteristics, intended use, and indications for use to previously cleared devices. It states that "The OpusDuo EC intended use and indications for use were previously cleared by FDA for the predicate devices" and that the "technical characteristics... are basically the same as those of the cleared..." predicate devices. It also mentions that "Laser output values of the OpusDuo EC are well within previous cleared values of the predicate devices as described."

The closest the document comes to mentioning performance criteria and validation is:

• Performance Standards: The device complies with U.S. Federal Performance Standards 21 CFR 1040.10 and 21 CFR 1040.11 for Class IV Laser Products, and voluntary standards EN 60601-1, EN 60601-1-2, EN-601-2-22, EN-60825-1, CISPR 11: 1997, class B and IEC 61000-4-2/3/4/5: 1995, EMI -EN55011 :1991, IEC 801:1991. These standards cover aspects like electrical safety, electromagnetic compatibility, and laser safety features (interlock protective housing, laser emission indicators, etc.).
• Validation Testing: "Validation testing has confirmed that the design of the additional accessories, which are required for the new applications, satisfies their technical specification." This indicates accessory validation, not necessarily the clinical or diagnostic performance of the laser system itself for its stated indications.

Given this context, I cannot generate the requested table and detailed study information as it is not present in the provided text. The document's purpose is to establish substantial equivalence for market clearance, not to detail a clinical performance study with acceptance criteria, ground truth, and expert adjudication.

The Twilight™ dental diode laser system may be used to perform several dental applications. Twilight™ uses advanced laser technology to incise, excise and ablate intraoral soft tissues safely and effectively. A Gallium Aluminum Arsenide (GaAIAs) solid state laser diode provides optical energy to oral soft tissues. A flexible fiberoptic handpiece delivers the Twilight™ laser energy. A visible light emitted from the handpiece distal end pinpoints the area of treatment. The optical power output and pulse may be adjusted to specific user requirements.

The provided document is a 510(k) premarket notification for a medical device called "Twilight™," a dental diode laser system. The document focuses on demonstrating substantial equivalence to previously cleared devices rather than presenting a de novo study with specific acceptance criteria and performance data.

Therefore, many of the requested sections (acceptance criteria, device performance, sample sizes, expert involvement, adjudication, MRMC studies, standalone performance, and detailed ground truth for test and training sets) are not explicitly available in this type of submission.

The core of this 510(k) is to establish that the Twilight™ laser is "substantially equivalent" to predicate devices already on the market. This often means demonstrating similar technological characteristics, intended uses, and safety profiles, rather than conducting new clinical trials to prove efficacy against specific, new acceptance criteria.

However, based on the information provided, here's what can be inferred and stated regarding your request:

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

This document does not specify quantitative acceptance criteria or report specific device performance metrics (e.g., success rates, precision, accuracy) from a dedicated study. The "acceptance criteria" for this 510(k) submission are implicitly tied to demonstrating substantial equivalence to predicate devices, meaning it performs similarly and is as safe and effective for its indicated uses.

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/Not provided. This submission does not describe a clinical study with a "test set" in the context of evaluating novel performance. Instead, it relies on the known performance and safety of predicate devices.
• Data Provenance: Not applicable/Not provided. No specific study data is presented. The "evidence of equivalence" is based on comparing the Twilight™ device's specifications and intended uses to those of existing, FDA-cleared predicate devices.

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/Not provided. No clinical study requiring expert-established ground truth is described.
• Qualifications of Experts: Not applicable/Not provided.

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

• Adjudication Method: Not applicable/Not provided. No clinical study requiring adjudication is described.

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: Not applicable. This document pertains to a medical device (laser system) and not an AI/imaging diagnostic device that would typically involve human readers or AI assistance in interpretation.

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

• Standalone Performance: Not applicable. This document is for a physical medical device (laser system), not an algorithm or AI system.

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

• Type of Ground Truth: Not applicable/Not provided. No new ground truth was established for this submission. The "ground truth" for demonstrating substantial equivalence rests on the established safety and effectiveness of the predicate devices for their approved indications.

8. The sample size for the training set

• Sample Size for Training Set: Not applicable/Not provided. No training set for an algorithm is relevant to this device submission.

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

• Ground Truth for Training Set Establishment: Not applicable/Not provided.
