초록
본 연구는 전문가 미백제로 많이 사용되고 있는 35% hydrogen peroxide를 사용하여 인공적으로 변색시킨 법랑질에 노출시킨 후 법랑질의 색, 경도 및 표면변화에 미치는 영향을 평가하여 다음과 같은 결론을 얻었다. 1. 35% HP 미백처리군의 색조변화량(
The purposes of this study were to examine the effect of 35% hydrogen peroxide (HP) bleaching agent on the changes in physical and chemical characteristics of tooth. The bleached teeth showed an apparent color changes. The whiteness increased linearly within the tested period as the period of bleaching increased. The microhardness between bleached groups after bleaching showed any statistically significant difference according to the paried t-test. The bleached enamel surface showed any apparent morphological changes compared to the enamel which was stored in distilled water only. The difference of the total mineral contents for the distilled water and hydrogen peroxide did not show statistical significance. These results demonstrated that bleaching using 35% hydrogen peroxide were adversely affects application time of experimental group and may confirm the safety of using these agents for a short time in dentist-monitored bleaching.
