본 연구는 미백치약의 효능을 확인하고 미백치약으로 미백된 치아의 식음음료에 따른 재착색의 정도를 확인하고자 실시되었다. 30개의 치아를 두 그룹으로 나누어 미백치약의 효능을 평가하였고 평가된 치아는 다시 착색음료에 담가 색변화를 관찰하였다. 그 결과, 미백치약은 사용한지 21일부터 일반치약을 사용한 치아와의 색변화에서 유의한 차이를 확인할 수 있었다(p>0.05). 미백된 치아의 재착색에서는 오렌지주스에 담군 치아가 가장 색변화가 크고 분명하였으나 일반치약을 사용한 치아와 유의한 차이를 보이지는 않았다(p>0.05). 커피와 녹차에 담근 치아는 각각 15일, 5일부터 유의한 차이를 보였으며 (p>0.05), 녹차에 담근 치아가 음의 색변화가 더 높은 것으로 나타났다. 따라서, 본 실험에 사용된 대표적인 3개의 식음음료 중 커피와 녹차에서 미백된 치아에서 더 착색이 잘 일어나는 것을 확인하였다. The purpose of this study was to evaluate the tooth brightening of whitening dentifrice and to determine the tooth stain level over 20 days depending on beverages that have various pH values after using whitening dentifrice. Thirty teeth were randomly divided into two groups. Group 1 was provided with a whitening dentifrice for 3 minutes and group 2 was treated with a control dentifrice for 3 minutes thrice a day for four weeks. All teeth were photographed using a digital imaging system under a stereomicroscope (magnification, ×10). After four weeks, the ten teeth were immersed in the tea solution, another of ten teeth were immersed in the orange juice and the other of the teeth were immersed in the coffee solution. Three solutions were renewed each day for the appropriate groups. Stain development was monitored under a stereomicroscope daily over 20 days period by immersion of teeth in a tea, juice, coffee solution at room temperature (25℃) in individual container. Whitening dentifrice gave a statistically higher value of overall color change as compared to control dentifrice after 21 days (p<0.05). Stain level of whiten tooth immersed in orange juice was the grestest overall color change, but there was not statistically significant difference (p>0.05). On the other hand, stain level of whiten tooth immersed in coffee and green tea showed a statistically significant difference after 15 days and 5 days, respectively (p<0.05). Tooth immersed in green tea was higher negative value than control dentifrice. The tooth using whitening dentifrice was shown to be effectively whiter color than control dentifrice. However, stain level by orange juice, coffee and green tea has a strong staining effect.
