Intended Use

The LED Turbo is a dental curing light that is designed for use in the optic polymerization of dental resins and activation of bleaching materials.

Device Story

Handheld dental curing light; consists of handy unit and battery charger. Input: electrical power. Transformation: control circuit regulates power, timing, and LED temperature; high-intensity blue LED light source (440-490nm) conducts light via optical fiber to treatment area. Output: high-intensity light (1100mW/cm2) for photopolymerization of resins or activation of bleaching agents. Used in dental clinics by practitioners. Operator selects curing program (5, 10, 20, 40 seconds) and positions handpiece tip relative to resin or tooth surface. Higher intensity allows shorter treatment times compared to standard lights; benefits patient by reducing chair time while avoiding thermal tissue damage.

Clinical Evidence

Bench testing only. Performance testing confirmed the device's ability to cure resin and activate tooth bleaching agents within specified timeframes without causing thermal damage to tissue.

Technological Characteristics

Handheld dental curing light; high-intensity blue LED light source; wavelength 440-490nm; intensity 1100mW/cm2; 7.2V/1900mAh battery; AC100V-260V operation; optical fiber light guide; programmed control circuit for timing and temperature monitoring.

Indications for Use

Indicated for the polymerization of dental resins and the activation of bleaching materials in a dental setting.

Regulatory Classification

Identification

An ultraviolet activator for polymerization is a device that produces ultraviolet radiation intended to polymerize (set) resinous dental pit and fissure sealants or restorative materials by transmission of light through a rod.

Predicate Devices

#### 8.10 Legally market device equivalence:

Ultra-Lite 200E Plus 510k number: K023545 Manufacturer: Rolence Enterprise, Inc.

#### 8.11 Intended use:

The LED Turbo is a dental curing light that is designed for use in the optic polymerization of dental resins and activation of bleaching materials.

#### 8.12 Device description

The LED Turbo consists of a handy unit and a battery charger. The handy unit contains a programmed control circuit, high intensity dental blue LED light source, a light guide and a optical fiber that conduct light to the treatment area on the patient. The control circuit which governs the output power rate, timing and monitoring the temperature of the LED.

### 8.14 Comparison with equivalence marketed device:

Both the LED Turbo and the predicate curing lights offer multiple curing programs for photopolymerization of dental resins and activation of bleaching materials. These programs differ in the intensity of the light delivered and the length of the light exposure. The operational principles of the proposed and predicate devices are identical. The operator chooses the appropriate program and sets the treatment parameters, if necessary. The tip of handpiece if oriented appropriately relative to the material being photopolymerized, or the tooth surface (for bleaching procedures), and the selected treatment is initiated.

The major difference between the proposed LED Turbo Gun and the predicate curing lights is the intensity of the light power delivered. The increased light intensity of the proposed LED Turbo allows the resin curing and tooth whitening agent activation to be conducted in a much shorter timeframe. Performance testing has been conducted that confirms that the halogen light technology used for LED Turbo is able to cure resin and activate tooth bleaching agents within the specified timeframe without causing thermal damage to the tissue.

The Similarities in intended use, technical specifications, and functional performance between the LED Turbo and Ultra-Lite 200e Plus leads to a conclusion of substantial equivalence between the proposed and predicate devices.
