The curing LED module provides high intensity light in the range of 430-490nm. The white light transillumination LED module (400-700nm) is provided as an aid for illuminating anatomy in the oral cavity.

AI/ML Overview

This document is a 510(k) premarket notification for a dental curing light, describing its substantial equivalence to a predicate device. It addresses the device's technical specifications and compliance with standards, but does not contain a study comparing its performance against specific acceptance criteria in a clinical or reader study context for an AI/ML device.

Therefore, most of the requested information regarding acceptance criteria, study design, sample sizes, expert involvement, and ground truth establishment, which are typical for AI/ML device evaluations, cannot be extracted from this document.

However, I can provide the available information about the device's performance in relation to international standards.

Acceptance Criteria and Device Performance

Acceptance Criteria	Reported Device Performance (Sirius Max Diode Curing Light)	Predicate Device Performance (VALO CORDLESS K110582)
IEC 60601-2-22 Standard: Curing Light output should vary from the device's setting by less than ± 20% of the setting.	The device's output measurements (ranging from 0.1 to 5.0W in all modes) varied by an average of only 1.4% from the unit's settings.	Satisfies this standard. (Explicit deviation not stated but implied by substantial equivalence)
Peak Wavelength: Primary peak at 460nm.	Single Peak wavelength at 460nm.	Primary peak at 460nm, small peak at 410nm. (Deemed substantially equivalent due to low energy and lower penetration depth of 410nm).
Compliance with Standards: (Implied acceptance criteria for safety and performance)	Complies with IEC 60601-1, IEC 60601-2-2, IEC 60601-2-22, ANSI/ADA 48-2. Bench tests performed: depth of cure, conformance to ANSI/ADA Specification No. 48-2, Temperature Control Validation, cleaning and disinfection validation, software verification and Validation and IEC 60601-1 Electrical Safety.

Device Description

Conformity to International Standards

The Sirius Max Diode Curing Light complies with the performance requirements as the predicate device: IEC 60601-1, IEC 60601-2-2, , and IEC 60601-2-22, ANSI/ADA 48-2. The following tests were performed in addition to bench tests described in the 510(k); depth of cure, conformance to ANSI/ADA Specification No. 48-2, Temperature Control Validation, cleaning and disinfection validation, software verification and Validation and IEC 60601-1 Electrical Safety.

Comparative Performance Data

The Sirius Max Diode Curing Light has been tested side-by-side against the predicate device. Measurements of the subject devices output ranging from 0.1 to 5.0W output all modes were shown to vary from the unit's settings by an average of only 1.4% in all modes. The intended performance of these devices, based on IEC 60601-2-22, is that Curing Light output should vary from the device's setting by less than ± 20% of the setting. Both the subject and predicate devices have been shown to satisfy this standard.

{5}------------------------------------------------

Comparison of Features and Characteristics

Table 1, following, lists key Features and Characteristics of the subject and predicate devices. Note that the slight change in verbage of Indications for Use is intended to more accurately describe the process of photo-activation of dual cured materials where curing is initiated but not completed by the light activation process. The SiriusMax also has 9 different timer settings for the curing modes compared to 8 found on the predicate device however, output intensities are in the same range and testing was done to validate the depth of cure and confirm substantial equivalence. The SiriusMax has a single Peak wavelength at 460nm whereas the predicate device has a primary peak at 460nm and a small peak at 410nm. The low enerqy of the small peak at 410nm combined with the fact that the vioilet wavelengths have lower penetration depth than blue wavelenghths makes the 460nm the predominant activator and therefore the subject and predicate are substantially equivalent.
