Abstract

The aim of this study was to evaluate the efficacy of bleached tooth with white toothpaste on the whitening effect, microhardness test. Forty-four human interior teeth were randomly assigned to two groups as follows: Group 1 was used general toothpaste as control, Group 2 exposed to white toothpaste at 3 times a day for 3 minutes. The total application time was 4 weeks. After each application, all tooth were washed with distilled water and immersed in artificial saliva. The color change and microhardness were measured using CIELab Color system and microhardness tester. The data were analyzed by student t-test, using SPSS 20.0 statistical computer program (SPSS Inc., USA). The overall color changes (${\Delta}E$) by white toothpaste have a capability of the whitening efficacy by factor of 2.3 times larger compared with general toothpaste. Moreover, the application of white toothpaste did not cause any microhardness reduction on enamel surface.

삶이 풍요로워지고, 경제적인 가치가 높아짐에 따라, 미용적인 부분이 부각되어져 최근 다양한 특수한 목적을 가진 성분이 포함된 치약이 시판되고 있다. 그 중 미용과 가장 밀접한 관계를 가지는 치아미백치약의 연구 개발되었다. 본 연구에서는 미백효과를 가지는 치아미백치약을 4 주간 사용 하였을 때 치아의 색변화, 법랑질 표면에 미치는 영향을 비교 분석하고자 한다. 미백치약의 사용에 따라 미백이 이루어지는 것을 알 수 있었으며, 4주간 반복 적용을 통하여 일반치약에 비하여 색변화가 약 2.3배 높은 수치를 보이는 것을 관찰하였다. 또한, 치아의 미세경도의 수치는 영향을 미치지 않는다는 것을 확인하였다. 이는 누구나 보다 쉽게 일상생활에서 미백효과를 나타내기 위하여 미백치약으로 잇솔질을 수행함으로써 미용 기능을 증진을 이끌 수 있는 방법으로 사료된다.
