Abstract

The aim of this study was to evaluate the effect of fluoride varnish application on enamel decalcification. Eighty bovine enamel blocks divided randomly into 4 groups. Group I is the control group. Group II was treated with the APF gel and washed after 4 minutes. Group III and IV was treated with Fluor $Protector^{(R)}$ and $CavityShield^{TM}$ and washed after 1 minutes. Decalcification were created by placing all specimen into artificial acidic solution(pH 4.0). Then the optical density of the lesions were measured by visible light fluorescence and the lesion depths were measured. The results were : 1. The optical density of group II was higher than group I but lower than group III, IV(p<0.05) and there was no difference between group III, IV(p>0.05) at 48 hours. 2. The optical density of group IV was highest at 72 hours(p<0.05). 3. Mean lesion depths were $205.36{\pm}42.85{\mu}m$ and $210.81{\pm}44.60{\mu}m$ in group I, II but no significant difference between two groups(p>0.05). 4. Mean lesion depths were $80.03{\pm}21.66{\mu}m$ and $77.46{\pm}27.72{\mu}m$ in group III, IV but no significant difference between two groups(p>0.05). Fluoride varnish treatment resulted in a significant reduction in lesion depth compared with APF gel. Fluor $Protector^{(R)}$ and $CavityShield^{TM}$ provided the similar effect.

이 연구의 목적은 법랑질 탈회부위에 불소 바니쉬 적용의 효과를 평가하는 것이다. 80개의 소의 법랑질 블록을 무작위로 4군으로 나누었다. 1군은 대조군으로 바니쉬 적용을 하지 않았다. 2군은 APF gel을 도포하고 4분후에 세척하였다. 3군과 4군은 Fluor $Protector^{(R)}$$CavityShield^{TM}$를 도포하고 1분 후에 세척하였다. 모든 표본을 인공우식용액 속에 넣어서 탈회시켰다. 가시광선 형광을 이용해 병소의 광밀도를 측정하고 병소의 깊이를 현미경으로 측정하고 통계적으로 비교하였다. 1. 48시간 후 광밀도 측정시 2군 광밀도는 대조군에 비해서 높았으나 바니쉬군보다 낮았고, 두 가지 바니쉬 간에 유의한 차이는 없었다. 2. 72시간 후 광밀도 측정결과 3군에서만 약간의 광밀도 감소가 관찰되고, 4군이 가장 높았다. 3. 72시간의 탈회 후 병소의 깊이를 측정한 결과 대조군에서는 평균 $205.36{\pm}42.85{\mu}m$, 2군에서 병소의 평균깊이는 $210.81{\pm}44.60{\mu}m$로 두 군간에 유의한 차이는 없었다. 4. 불소 바니쉬군의 병소 깊이는 3군이 $80.03{\pm}21.66{\mu}m$, 4군이 $77.46{\pm}27.72{\mu}m$로 대조군이나 2군에 비해 탈회가 억제되었음을 알 수 있었으나 두 가지 바니쉬 사이에 차이가 없었다.
