- Abstract
- The aim of this study was to evaluate the effect of fluoride varnish application on enamel decalcification. Eighty bovine enamel blocks were divided randomly into 4 groups. No application was performed on groupI, which acted as the control group. Group II was treated with the APF gel and was washed after 4 minutes. Group III and IV was treated with Fluor Protector and CavityShield™ was 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 body of the lesion depths were measured and compared statistically.
The following results were obtained :
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 48hours.
2. The optical density of group IV was highest level at 72hours(p<0.05).
3. Mean body of the lesion depths were 205.36±42.85μm in group I and 210.81±44.60μm in group II. but no significant difference between two groups(p>0.05).
4. Mean body of the lesion depths were 80.03±21.66μm and 77.46±27.72μm in group III, IV. There was no significant difference between two groups(p>0.05).
Fluoride varnish treatment prior to decalcified lesion formation resulted in a significant reduction in lesion depth compare with APF gel. Fluor Protector and CavityShield™ provided the same degree of protection effect.
