불화물이 첨가가 아연화유지놀의 압축강도, 이차 우식에 대한 저항성, 변연누출에 미치는 영향에 관한 실험적 연구 = EFFECT OF ADDITION OF FLUORIDE TO ZINC OXIDE EUGENOL ON COMPRESSIVE STRENGTH , RESISTANCE TO SECONDARY CARIES AND MARGINAL LEAKAGE IN VITRO

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effect of addition of fluoride to conventional zinc oxide eugenol on compressive strength, resistance of enamel to secondary caries and marginal leakage. Groups were divided by adding materials and their content. Group 1 was control group that did not contain fluoride, Group 2 was 10% sodium fluoride group, Group 3 was 20% sodium fluoride group, Group 4 was 10% stannous fluoride group and Group 5 was 20% stannous fluoride group. Each of four experimental groups was compared with control group.
The results were as follows:
1. In compressive strength after 3 days, 10% stannous fluoride group was highest and then 20% sodium fluoride group, 10% stannous fluoride group, 10% sodium fluoride group, and non-fluoride group were in order. Compressive strength after I day water soaking after 3 days was stastically not significant(p>0.05).
2. In resistance of enamel to secondary caries, hardness reduction rate of experimental groups was lower than control group. There was no significant difference among groups(p>0.05).
3. Sodium fluoride group showed less marginal leakage than stannous fluoride group(p<0.05).
4. The amount of fluoride release was largest in 20% sodium fluoride group, and then 10% sodium fluoride group, 20% stannous fluoride, 10% stannous fluoride group were in order.
