Intended Use

Dentlight Oral Exam Light Kit is indicated for providing illumination to aid visualization during oral procedures and an adjunct to enhance the visualization for oral examination of mucosal abnormalities and oral lesions.

Device Story

Dentlight Oral Exam Light Kit is a rechargeable, cordless, handheld device for dental and physician office use. It utilizes interchangeable LED light heads (white and violet) to provide illumination and excitation for tissue reflectance and fluorescence visualization. The system includes custom fluorescence loupe filters, filter caps, a charging stand, and patient protective eyewear. The operator selects the appropriate wavelength to illuminate the oral cavity; tissue abnormalities are visualized through the filtered loupe. The device improves clarity, portability, and ease of use compared to traditional corded systems. It aids clinicians in identifying mucosal abnormalities and oral lesions, potentially facilitating earlier detection and improved clinical decision-making.

Clinical Evidence

Bench testing only. Performance evaluation included optical power testing, optical wavelength verification, beam quality assessment, and evaluation of illumination and fluorescence imaging. The device complies with electrical safety requirements per IEC 60601-1-2.

Technological Characteristics

Cordless, rechargeable battery-powered unit. Features interchangeable LED light heads (white and violet) for illumination and excitation. Includes fluorescence loupe filters and filter caps. Operates via LED light source in multiple wavelength spectra. Complies with IEC 60601-1-2 for electrical safety.

Indications for Use

Indicated for use by dentists and physicians to provide illumination during oral procedures and as an adjunct to enhance visualization of mucosal abnormalities and oral lesions in patients.

Regulatory Classification

Identification

An ultraviolet detector is a device intended to provide a source of ultraviolet light which is used to identify otherwise invisible material, such as dental plaque, present in or on teeth.

Predicate Devices

• Velscope (K070523)

### 2. DEVICE NAME

Proprietary Name: Dentlight Oral Exam Light Kit Common/Usual Name: Oral Examination Light Classification Name: Ultraviolet Detector (872.6350)

# 3. PREDICATE DEVICES

Velscope (K070523) by LED Medical Diagnostics Sapphire O/E Oral Examination System by Den-Mat Holdings (K073483) Identafi 3000 (K090135) by Trimira, Remicalm

# 4. DEVICE DESCRIPTION

Dentlight Oral Exam Light Kit is a rechargeable-battery-powered cordless unit designed for if!umination and examination for dental and physician's office on any procedures which require a small homogenous and well-defined spot and natural tissue reflectance and fluorescence visualization of healthy and abnormal tissue.

Dentlight Oral Exam Light Kit consists of a cordless unit with interchangeable light head (White and Violet), custom adaptable Fluorescence Loupe Filters and Filter Caps, Charging Stand, Power Adapter, and Patient Protective Eyewear Goggle.

# 5. INTENDED USE

Dentlight Oral Exam Light Kit is indicated for providing illumination to aid visualization during oral procedures and an adjunct to enhance the visualization for oral examination of mucosal abnormalities and oral lesions.

{1}------------------------------------------------

# 6. TECHNOLOGICAL CHARACTERISTICS AND SUBSTANDTIAL EQUIVALENCE

Dentlight Oral Exam Light Kit is substantially equivalent to K070523, K073483, and K090135 in intended use and operation; each uses fluorescence and/or reflectance as the primary mode for enhanced visualization of tissue for determining oral tissue abnormalities.

Predicate K070523 uses 120V AC powered metal halide light to produce a single I redicate 1070522 about views fluorescence through a connected handpiece with a filtered lens.

Predicate K073483 uses 120V AC powered Xenon plasma arc light and filters to produce a single collimated blue light and views fluorescence through a connected handpiece with a filtered lens.

Predicate K090135 uses AA-battery-powered low power LED light to produce a r iour light at near site to tissue and view fluorescence through a broadband polarized filter glass. A selectable wavelength mechanism is built in with polarized white and amber LED lights that compliment fluorescence image.

Dentlight Oral Exam Light Kit offers two illumination modalities and one Dommon detection/viewing mechanism. Both illumination modalities use LED light source in multiple wavelength spectra as illumination or excitation source fight bour cuorescence/reflection. The operational principles of the proposed and rer ticate devices are identical with the primary mode for enhanced visualization of tissue through fluorescence. The operator chooses the appropriate wavelength light source to illuminate regions of oral cavity for inspection.

The major differences between the proposed Dentlight Oral Exam Light Kit and the predicate devices are the magnified high contrast filter used in the detection/viewing, the illumination intensity, size, weight and portability of the device. The increased light intensity of the proposed Dentlight Oral Exam Light detrioe. The moreason LED allows the illumination and excitation with improved clarity. The improved portability with cordless hands free operation or wand operation enables better, easier and faster exam procedures. The size and weight is a benefit to constant patient operations and counter space.

# 7. PERFORMANCE TESTING AND COMPLIANCE

The following testing was conducted to evaluate the functionality and performance of the proposed Dentlight Oral Exam Light Kit:

- Optical Power Testing .
- Optical wavelength .
- Beam Quality .
- Illumination and Fluorescence Image .
