Abstract

Blue light with strong energy is required for light-curing resin treatment, which is being used more frequently in dentistry. To reduce the risk of exposure to scattered light, we tried to use colored lenses. The tips for light curing machine and a commercially available yellow-type blue-light blocking lens and a yellow lens colored with yellow dye, which are expected to be effective in blocking blue light, were placed in a UV-Vis spectrometer device, and transmission and blocking of blue light were tested respectively. As a result, the average blue light blocking rate of the light curing machine tips was 99.49%, and the C lens with the highest color density among commercially available lenses showed a high blue light blocking rate of 99.54%. In the case of lenses tinted with yellow, the yellow tinted C lens with the highest tint concentration showed 87.57% of blue light blocking rate. It is judged that the side effects related to the eyes caused by blue light can be reduced if a yellow-type commercially available or colored lens is worn along with a light curing machine tip during resin treatment.

치과에서 사용횟수가 증가하고 있는 광중합형 레진 치료에는 강한 에너지를 가진 청색광이 필요하나, 그 빛은 산란 또한 커서 눈과 관련된 여러 부작용이 나타난다. 산란되는 빛에 노출되는 위험을 줄이고자 색깔 렌즈를 활용해보고자 하였다. 광중합기용 팁들과 청색광 빛의 차단에 효과가 있을 것으로 기대하는 시판용 노란색 계열의 청광 차단 렌즈와 노란색 염료로 착색한 노란색 렌즈를 UV-Vis 스펙트로미터 기기에 놓고 각각 청색광의 투과와 차단을 실험하였다. 결과로 광중합기용 팁들의 청광차단율 평균은 99.49%, 시판용 렌즈들 중 색 농도가 가장 높은 C 렌즈는 99.54%의 높은 청광차단율을 보였다. 노란색으로 착색한 렌즈의 경우에는 착색 농도가 가장 짙은 노란색 착색 C 렌즈가 87.57%의 청광차단율을 보였다. 레진 치료 시 광중합기용 팁과 함께 노란계열의 시판용 렌즈나 착색 렌즈를 착용한다면 청색광에 의한 눈과 관련된 부작용들을 줄일 수 있을 것으로 판단된다.
