초록

1960년대 광중합 레진이 소개된 이후 현재의 수복학에서 광중합은 중요한 과정으로 고려되고 있다. 광중합을 위한 다양한 중합기들이 소개되어서 발전하면서 사용되어져 왔다. Quartz-tungsten-halogen (QTH) 광중합기는 1990년도까지 널리 사용되었으며 2000년 들어 LED 광중합기가 널리 사용되고 있다. 1세대 LED 광중합기는 여러 개의 LED가 출력을 내는 광중합기로 QTH 광중합기에 비해 높은 출력을 내짐 못했다. 2세대 LED 광중합기는 하나의 LED로도 충분한 출력을 낼 수 있게 되었으며, camphoroquinone (CQ) 이외에 부가 중합개시제를 고려하여 3세대 polywave 중합기가 시장에 출시되었다. 현재는 LED에서 방출하는 빛이 계속 switching되는 4세대 광중합기가 개발되어 출시되었다. 이러한 LED 광중합기의 발전에 따라 사용하는 광중합기의 대부분이 LED 광중합기로 자리잡고 있다. LED 광중합기의 사용의 증가에 따라 임상가들은 광중합기의 특성을 이해하고 있어야 한다. 본 리뷰 논문의 목적은 LED 광중합기에 대한 세대별 분류와 특징에 대한 정보를 주기 위함이다.

Since light curing composite resin was introduced in the 1960s, light curing process has been considered as an essential process. Herein, various light sources became available for the process. Quartz-tungsten-halogen (QTH) light curing units (LCUs) dominated the market until the 1990s, before the LED LCUs started replacing them in the 2000s. The LED, developed approximately 50 years ago, came into use in the dentistry field from the late 1990s, and the LED LCUs, with the 2000s. Since then, the LED LCUs have gone through many advancements to its current fourth generation. In accordance to such advancements of the LED light curing unit, the majority of light curing unit used today are LED LCUs. As much as its usage has increased, it is necessary that dental clinicians understand the characteristics of the device. The objective of this review report is to provide the history of the scientific development and describe the characteristics of the LED LCUs.
