Device Story

LED Curing Light (Model CV-215) is a handheld dental device used by dentists to polymerize light-sensitive dental materials. The device utilizes a high-power LED to emit visible blue light (430nm–490nm) at intensities between 1000mW/cm² and 1800mW/cm². It features two operational modes (TURBO and NORMAL) with preset exposure times, controlled via buttons on the main unit. The device is powered by a rechargeable lithium battery. During operation, the clinician directs the light output onto the dental composite or cement to initiate polymerization. The device includes a curing light shield for eye protection. The main unit is constructed from ABS and aluminum, with an ABS light guide base. The device is intended for use in hospitals or professional dental clinics to facilitate dental restorations.

Clinical Evidence

No clinical data required. Safety and performance were established through bench testing, including light output performance (ANSI ADA 48:2004, IEC 80601-2-60), electrical safety (ANSI/AAMI 60601-1), electromagnetic compatibility (IEC 60601-1-2), and biocompatibility (ISO 10993-5, ISO 10993-10).

Technological Characteristics

Handheld LED curing light; 5W high-power blue LED source; 430-490nm wavelength; 1000-1800mW/cm² intensity. Materials: ABS plastic (light guide base), ABS/Aluminum (main unit). Power: Rechargeable Li-ion battery (IEC 62133). Standards: ANSI/AAMI 60601-1, IEC 60601-1-2, IEC 80601-2-60, ADA 48, ISO 10993-5/10.

Indications for Use

Indicated for light curing polymerization of dental composites, luting materials, cements, and other light-cured materials in dental patients. For use by trained dental professionals in clinical settings.

Regulatory Classification

Identification

#### Device Description 4.

LED Curing Light is used to restore teeth on dental patient. The device can only be used by the dentist who is qualified and well trained. This product is used on dental patient in the place of hospital or professional medical site.

LED Curing Light adopts the principle of ray radiation to solidify the light sensitive resin by shooting at it in a short time. It is composed of high-power LED, main unit, curing light shield, charger and charge station. The main unit contains the ON/OFF button, display screen, mode button and time button.

LED Curing Light provides TURBO mode and NORMAL mode with different preset exposure time. The high-power LED can produce visible blue light in the 430nm to 490nm waveband of spectrum with a power density of 1000m W/cm² to 1800m W/cm². Using different modes gives dental professionals the flexibility to polymerize virtually almost all types of composites, boding agents and sealants available in the market.

The enclosure of main unit was composed of ABS material and Aluminum, and the light guide base (patient contact part) was made from ABS material.

#### 5. IntendedUse/ Indication for Use

For light curing polymerization of dental composites, luting materials, cements and other light cured materials.
