초록
본 연구의 목적은 와동 충전시 충전재와 치질 사이에 개재되는 상아질 결합제가, 수복물에서 유리되는 불소가 와동 벽으로 침투하는 과정에 어떠한 영향을 주는지를 조사함이었고, 부가적으로 레진 강화형-글라스 아이오노머 시멘트의 접착에도 상아질 결합제를 도포 하는것이 치질과의 결합력을 강화시킬 수 있는지에 대해 평가하고자 하였다. Fuji II
It is well known that glass-ionomer cement and compomer can release fluoride which can inhibit the progression of dental caries. The purposes of this study were to evaluate whether the fluoride from fluoride-containing filling materials can penetrate the dentin bonding adhesive and the dentin bonding adhesive can increase the bond strength of resin-modified glass ionomer. The amount of fluoride release from resin-modified glass ionomer and compomer was measured during 28 days of period and statistically analyzed by t-test. The bond strength of each material with/without dentin bonding adhesive was measured and also statistically analyzed by t-test. The distribution of fluoride from each material into the tooth was explored by electron probe microanalysis system(EPMA). The experimental teeth used were second primary molars about to exfoliate. The amount of fluoride release from each material was diminished by dentin bonding adhesive during 28 days(p<0.05) and the bond strength was not increased by dentin adhesive in resin-modified glass ionomer. The bond strength of group VI was not detectable. The distribution of fluoride from each material into teeth was according to dentino-enamel junction and dispersed into pulp from pulpal floor. The widest distribution was shown in resin-modified glass ionomer cement filled without the application of dentin bonding adhesive.
