Whitening: D-Laser Blue and D-Laser 16 are indicated for light activation for bleaching materials for teeth whitening and for laser-assisted whitening/bleaching of teeth.
Low Level Laser Therapy: D-Laser Blue and D-Laser 16 are intended to emit energy in the red and infrared spectrum to provide topical heating for the purpose of elevating tissue temperary relief of minor muscle and joint pain and stiffness, minor arthritis pain, or muscle spasm, and for the temporary increase in local blood circulation and/or temporary relaxation of muscles.
The dental diode laser systems, D-Laser Blue and D-Laser 16, realize oral soft tissue surgery, periodontal disease, endodontic disease, pain treatment, soft laser therapy and other oral diseases by vaporizing, carbonizing and solidifying the tissue by laser. The device features include: Using a capacitive touch screen which has the clear display and is easy to operate; Builtin large-capacity rechargeable lithium battery with longer time of endurance; The handpiece sleeve and the fiber tip can be autoclaved to prevent from cross infection; Preset more than 20 treatment procedures to reduce the difficulty of use; A secure protection mechanism that automatically shuts down the device after 5 minutes of inactivity.
The D-Laser Blue and the D-Laser 16 respectively consist of a main unit, a laser transmission system and a power adapter. The main unit includes a semiconductor laser, a power supply system and a control device, a safety protection device and a display device.
The D-Laser Blue employs the diodes with wavelengths of 976nm, 650nm and 450nm, and the device emits laser output energy in the infrared, red and blue spectra respectively. The D-Laser 16 employs the diodes with wavelengths of 976nm and 650nm, and the device emits laser output energy in the infrared, red spectra respectively.
The provided text does not contain typical acceptance criteria and a study design for evaluating a medical device's performance in terms of diagnostic accuracy (e.g., sensitivity, specificity). Instead, this document is a 510(k) summary for laser surgical instruments (D-Laser Blue and D-Laser 16), primarily focusing on demonstrating substantial equivalence to legally marketed predicate devices.
The "acceptance criteria" presented are primarily comparisons of technological characteristics, indications for use, and a list of non-clinical tests confirming compliance with various electrical, safety, and biocompatibility standards. The study mentioned is a non-clinical comparison of cutting efficiency.
Therefore, many of the requested fields (such as sample size for test set, data provenance, number of experts for ground truth, adjudication method, MRMC study, standalone performance, training set sample size, and training set ground truth establishment) are not applicable to the type of information presented in this 510(k) summary.
Here's an attempt to extract and format the available information according to your request, with "N/A" for criteria not present in the document.
1. Table of Acceptance Criteria and Reported Device Performance
For medical devices like the D-Laser Blue and D-Laser 16, substantial equivalence is often demonstrated by showing that the proposed device has the same intended use and similar technological characteristics to a predicate device, or that any differences do not raise new questions of safety or effectiveness. The "acceptance criteria" here are largely met by demonstrating these similarities and confirming compliance with relevant standards and functional tests.
