초록

본 연구에서는 자가 미백제로 많이 사용되고 있는 10% CP를 이용하여, 불소가 함유되지 않은 미백제, 불소가 함유된 미백제, 그리고 10% CP로 미백한 후에 불소를 적용하여 하루에 8시간씩 14일 동안 처리함으로써, 치아표면의 색과 미세경도에 미치는 영향을 평가하여 다음과 같은 결론을 얻었다. 1. 색조 변화측정 결과, 대조군을 제외하고 미백 처리한 모든 군에서 치아 미백 후 시간 경과에 따라 $L^*$ 값과 ${\Delta}E^*$ 값에 유의한 차이가 있었고(p<0.05), 비슷한 수준의 미백효과와 함께 치아의 색조에서 노란색이 감소됨을 관찰할 수 있었다. 2. 미백 처리 전후의 법랑질의 표면경도를 분석한 결과 대조군에서는 별 차이를 보이지 않았으나, 미백 처리한 모든 군에서 유의한 미세경도 감소를 보였다(p<0.05). 특히 10% CP군은 가장 낮은 미세경도 수치를 보였고, 미백제에 불소가 함유된 군과 미백 후 불소를 적용한 군은 미세경도 감소폭이 줄어들었다. 이상의 결과를 종합해 보면, 2주간 진행되는 10% CP는 치아미백에 효과적이며, 미백제에 불소를 함유시켜도 미백에는 영향을 주지 않았으며, 표면미세경도는 불소가 함유되지 않은 미백제에 비해 덜 감소했다. 임상에서 미백으로 인한 부작용을 최소화하는데 적정 농도의 불소를 이용해 적용될 수 있도록 더 많은 연구가 이루어져야 할 것으로 사료된다.

The aim of this study were to elucidate effects of fluoridated bleaching agents and post-treatment fluoride application on the color and microhardness of enamel surface. Twenty freshly extracted human adult molar were each sectioned into halves, the specimens divided and treated according to four experimental groups: 1, untreated controls: 2, treatment with 10% carbamide peroxide (CP) bleaching agent; 3, treatment with 10% CP containing 0.11% fluoride; 4, treatment with 10% CP followed by a 0.9% sodium fluoride gel application. Group 2-4 were compared with the baseline data. treated 8 h per day for 14 days then immersed in distilled water for 2 weeks. Changes in enamel color and microhardness were evaluated on Days 7 and 14. All the bleached enamel specimens revealed increased whiteness and overall color value. Groups 2 and 4 showed significantly decreased enamel microhardness compared to their baseline. The specimens treated with fluoridated bleaching agents showed relatively less reduction in enamel microhardness than those treated with nonfluoridated agents during the bleaching treatment. The addition of fluoride did not impede the tooth whitening. The fluoridated bleaching agents reduced the microhardness loss of enamel.
