Abstract

This study evaluated the efficacy of an office bleaching gel (RemeWhite, Remedent Inc., Deurle, Belgium) containing 30% hydrogen peroxide. 31 volunteers were recieved office bleaching with the RemeWhite for 3 times at one visit, total 2 visits. As control group, the same gel in which hydrogen peroxide was not included was applied to 31 volunteers with the same protocol. The shade change (${\Delta}E^*$, color difference) of 12 anterior teeth was measured using Colorimerter and Vitapan classical shade guide. The shade change of overall teeth in the experimental group was significantly greater than that in the control group which was measured using Colorimeter. There was also a significant difference between baseline and 14 weeks or 26 weeks though color rebounding phenomenon occurred as time went by. Small shade change difference can be measured accurately using Colorimeter than using Vitapan classical shade guide.

30% 과산화수소를 함유한 전문가 미백제인 레메화이트(Remewhite, Remedent Inc., Deurle, Belgium)를 시험군 피험자 31명, 시험용 미백제에서 과산화수소를 제외한 동일한 제재를 대조약으로 대조군 피험자 31명에게 1일 3회씩, 2차례에 걸쳐서 시행하였다. 미백의 임상적 효용성은 Colorimeter, Vitapan classical shade guide를 이용하여 전체 색변화량$({\Delta}E^*)$을 측정하였다. 14주 후와 26주 후의 색변화량을 측정하여 군 간 색변화량을 비교하였고, 각 군 내에서의 색변화량도 비교하여 다음과 같은 결론을 얻었다. 1. Colohmeter를 이용한 평가시에 시험군에서 전체 색변화량$({\Delta}E^*)$은 대조군에 비해 통계적으로 유의한 차이를 보였고, Vitapan classical shade guide를 이용한 평가시에는 통계적으로 유의한 차이를 나타내지 않았다(p < 0.05). 2. 시간이 지남에 따라 색 복원 현상이 나타남에도 불구하고 미백 시행 14주 후와 26주 후에도 미백의 효과가 유지된다고 할수 있다. 3. Colohmeter를 이용한 평가시에 Vitapan classical shade guide를 이용한 평가시보다 작은 색변화량을 더 정확하게 측정할 수 있다.
