초록

본 연구에서는 4종류의 교정용 레진시멘트의 불소 유리량을 측정해 보고 탈회정도를 비교해 본 결과 다음과 같은 결과을 얻었다. 1. 불소 유리량은 불소를 포함한 실험군이 불소를 포함하지 않은 대조군에 비해 통계적으로 유의하게 높은 불소 유리량을 보였다(p<0.05). 2. 누적 불소 유리량은 불소를 포함한 실험군이 불소를 포함하지 않은 대조군에 비해 통계적으로 유의하게 높은 불소 유리량을 보였다(p<0.05). 3. 불소의 유리 양상은 모든 시편에서 실험 첫째 날 하루 동안 가장 많은 양의 불소를 유리하였다(p<0.05). 4. 탈회 후의 ${\Delta}F$값과 ${\Delta}Q$값의 절대값은 군 간에 통계적으로 유의하지 않았으나, 대조군에 비해 작았다(p<0.05). 5. 탈회실험 전 후의 ${\Delta}F$값과 ${\Delta}Q$값의 변화량의 절대값은 실험군이 대조군에 비해 작았다(p<0.05). 이상의 결과을 통해 불소를 포함한 교정용 레진 시멘트는 일정기간 불소를 유리하고, 법랑질 탈회를 예방함으로써 교정 치료 시 발생할 수 있는 초기 우식발생을 예방할 수 있다고 사료된다.

Objectives : The purpose of this study was to determine of fluoride-releasing of orthodontic resin cements containing fluoride and compare decalcification of tooth attached fluoride and non-fluoride resin cements. Methods : Total eighty premolar tooth were used in this study. Forty tooth were used for fluoride releasing measurement and forty tooth were used for decalcification measurement. Each forty tooth were randomly divided into four groups, and brackets were attached on tooth surface with Blugloo, Light Bond, Orthofolw(experimental groups) and Transbond cement(control group). After brackets were attached on tooth surface, forty tooth were immersed in artificial salival and then the quantity of fluoride releasing was measured ever day for 8days and then three-days intervals for 3 weeks. Forty tooth were immersed in decalcification solution for 48hours and then degree of decalcification was measured as lesion area, ${\Delta}F$, and ${\Delta}Q$ using QLF. The data were analysed by one-way ANOVA and Pearson's correlation coefficient using SPSS 12.0 program. Results : Fluoride release of experimental groups was higher than control group(p<0.05). Cumulative fluoride release of experimental groups was also higher than control group(p<0.05). There were the highest release during first day. ${\Delta}F$, and ${\Delta}Q$ was high TB > BG > OF > LB (p<0.05). Change of ${\Delta}F$, and ${\Delta}Q$ was also high TB > BG > OF > LB (p<0.05). As for correlation between fluoride release and lesion area, ${\Delta}F$, and ${\Delta}Q$ showed negative correlation but there was no significant difference. Conclusions : This study shows that orthodontic reins cements containing fluoride release fluoride and prevent initial enamel decalcification caused by orthodontic treatment.
