Abstract

This study is to examine the relation between Korean fermented food and discoloration on teeth, which have undergone profession tooth whitening. The color change of natural tooth, which has undergone professional tooth whitening, is objectively measured by dental colorimeter after being immersed in Korean fermented food for certain period. The tooth specimens used in this study are 30 pieces and measured 30 times per one tooth, 900 times totally by dental colorimeter ShadeEye NCC$^{(R)}$ Dental Chroma Meter. As a result of analyzing the collected data by using PASW(statistical package) 18.0, the significant difference is found (p<0.001) in lightness and yellowness before and after of professional tooth whitening. The lightness and yellowness after immersion is changed (p<0.001) according to time. As a result of examining the degree of discoloration based on type of fluids, the similar difference is indicated (p=0.001, p<0.001 1,2 and 3 weeks after getting professional tooth whitening. As a result, Korean traditional fermented food influences on discoloration on bleached tooth depended on the duration of immersion and the type of fluids. However, this study failed to represent internal oral condition accurately therefore the results of this study could be altered by the internal oral condition, frequency of consumption of food, and the management oral hygiene.

본 연구는 한국전통발효음식과 미백치아의 색조변화와의 관련성을 알아보고자 시행하였으며, 연구방법은 전문가 치아미백을 시행한 자연치아를 한국전통발효음식에 일정기간 침전 후 치과용 측색기를 이용하여 치아색조변화의 정도를 객관적으로 측정하였다. 본 연구에 사용된 치아시편은 30개로 한 치아당 30회 측정되었으며, 전체 측정 횟수는 900회 실시되었다. 측정은 치과용 측색기 ShadeEye NCC$^{(R)}$ Dental Chroma Meter를 사용하였다. 수집된 자료는 PASW 18.0을 사용하여 분석한 결과, 미백 전, 후 명도와 황색채도에서 유의한 차이가 나타났으며(p<0.001), 용액침전 후 명도와 황색채도는 시간에 따라 변화하였다(p<0.001). 침전용액에 따른 색조변화량의 차이를 알아본 결과, 미백 후부터 1주 동안, 2주에서 3주까지의 기간 동안 각 침전용액에 따라 유의한 차이가 나타났다(p=0.001, p<0.001). 한국전통발효음식은 침전기간과 침전용액에 따라 미백치아의 색조변화에 영향이 있음을 알 수 있었다. 하지만 본 연구는 구강 내의 상태 그대로를 재연하지 못하였기에 구강 내 상태, 섭취빈도, 구강위생관리에 따라 차이가 있을 것이다.
