Device Description

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.

AI/ML Overview

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.

Acceptance Criteria (Implicit from Substantial Equivalence Claim)Reported Device Performance (Implicit from Substantial Equivalence Claim)
Safe and effective operation for indications for use.The device "incise, excise and ablate intraoral soft tissues safely and effectively." "Twilight™ performs through the same mechanism as other diode laser technologies."
Equivalent performance specifications to predicate devices.Stated as "Equivalent performance specifications."
Equivalent intended uses to predicate devices.Stated as "Equivalent intended uses."
Equivalent mechanism of action to predicate devices.Stated as "performs through the same mechanism as other diode laser technologies."

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.

Indications for Use:

Incision, excision, vaporization, ablation and coagulation of oral soft tissues including:

Excisional and incisional biopsies Exposure of unerupted teeth Fibroma removal Frenectomy and frenotomy

Gingival troughing for crown impressions Gingivectomy Gingivoplasty Gingival incision and excision Hemostasis Implant recovery Incision and drainage of abscess Laser Assisted Uvulopaletoplasty (LAUP) This laser is effective for cutting, ablating, coagulating and removing oropharangeal soft tissue that has been diagnosed as anatomically abnormal or naturally occurring hypertrophic which has been identified and confirmed as being associated with chroninc palatal snoring.

Cautions and Contraindications:

All clinical procedures performed with Twilight™ must be subjected to the same clinical judgement and care as with traditional techniques. Patient risk must always be considered and fully understood before clinical treatment. The clinician must completely understand the patient's medical history prior to treatment. Exercise caution for general medical conditions that might contraindicate a local procedure. Such conditions may include allergy to local or topical anesthetics, heart disease, lung disease, bleeding disorders, sleep apnea or an immune system deficiency. Medical clearance from patient's physician is advisable when doubt exists regarding treatment.

Substantial Equivalence:

There are no unique applications, indications, materials or specifications presented herein. Twilight™ is identical to several other diode laser systems cleared by the FDA. Equivalent devices include: Premier, Aurora™(K954316), American Dental
Technologies, PulseMaster™ (K972325) and Dentek, LD-15 ™ (K974057) for general dental soft tissue applications, Premier, Aurora™ (K981379) for pulpotomy and American Dental Technologies, PulseMaster™ (K961269) and Premier, Aurora™ (K974586) for sulcular debridement.

Conclusion:

Twilight™ is substantially equivalent to several available, established dental diode laser products. Twilight™ performs through the same mechanism as other diode laser technologies.
