【Case Study】LED Dental Curing Light Registration in China

from CIRS by

1. Introduction

Product Name: LED Curing Light, Dental Curing Light

Product Composition:

1. Network power supply: main unit, power adapter, light guiding component, shading device, etc.

2. Internal power supply: main unit, power adapter, battery, light guiding component, charging stand, etc.

Working Principle: The light-emitting diode is used as a light source to emit a light source of a certain wavelength effective for the dental restoration material, and the light-conducting component collects light and is led out, so that the dental restoration material is rapidly solidified under the action of the radiation energy.

Typical Structure:

2. Classification

Classification Code: 17-03-06 Class II curing equipment

Product Description: It usually consists of a light source handle and a power supply. By emitting light of a specific wavelength and utilizing the principle of photopolymerization, the photocurable material is rapidly and efficiently polymerized and cured in a short time. The light source has two types: quartz tungsten halogen lamp and LED lamp.

Expected Usage: Used to cure photocurable materials.

3. Registration Unit

Classified by light source:

1. Light curing device with quartz tungsten halogen lamp as light source

2. Light curing device with light emitting diode (LED) lamp as light source

Classified by power supply:

1.1. Stand-alone device, a light curing unit powered by a power supply network (including the type that can be used with either a network power supply or an internal battery)

1.2. Accessories, the dental treatment machine is only powered, clinically adjusted by the curing machine itself to the treatment mode and the output of light energy

1.3. Accessories, which is a built-in module of the dental treatment machine. Powered by the dental unit and adjusted by the control panel of the dental unit to the treatment mode and light energy output of the curing unit

2. Stand-alone device, light curing unit powered by internal battery (e.g. rechargeable battery)

Note:Different light source and power supply should be divided to different registration units, but the LED curing light with power supply 1.1 and 1.2 (having charging base)

The blue light is irradiated by the repairing material to cure the material, and the light curing machine is divided into a quartz tungsten halogen lamp as a light source and an LED light curing device which is a light source (LED) lamp as a light source. Product performance indicators use the applicable parts of the following reference standards, such as: YY 0055 light curing machine series standards.

6. Registration Cost and Duration

1) Product Testing

Test items

Testing duration(90 working days total)

Testing fee(USD)

Safety Performance










1. The price of EMC is only the price of one operating mode. If there are multiple operating modes, it needs to be re-priced;

2. Biocompatibility is only the price of a single material, such as a variety of materials and human contact, need to accumulate;

3. Biocompatibility is only the way the material and the human body are in contact with the oral mucosa, short-term contact within 24h

2) Technology Approval

60 working days

Another 60 working days if the 1-year supplement is required

3) Administrative Approval

20 working days
