수종의 치과용 접착제 용매의 증발에 관한 연구

Abstract

The purpose of this study was to evaluate the characteristics of the evaporation for various kinds of the dental adhesives by the measurement of the evaporation rates and the rates of volatile parts in adhesives. OptiBond FL (Kerr, FL), CLEARFIL SE BOND (Kuraray, SE), OptiBond S (Kerr, OS), and OptiBond All-In-One (Kerr, OA) were used in this study. 10 ㎕ of adhesive was dispensed on slide glass and weighted by precision balance. Adhesive was dried for 10 sec and 30 sec by hair dryer and weighted. Until the weight of the adhesive became constant, adhesive was stored for 48 h at 37℃ in dark oven and then weighted. The results were statistically analyzed using One-way ANOVA and Scheffe test at p = 0.05 level. The evaporation rate of OA was significantly higher than other groups (p < 0.05). Significant differences were observed between two air-drying times of all groups except for OS. The rate of volatile part of FL was significantly higher than other groups (p < 0.05) and the rate of volatile part of OS was significantly lower than other groups (p < 0.05). The evaporation rates and rates of volatile parts were different according to kinds of adhesives and solvents. Also, both air-drying times should not remove the solvents of adhesives completely. More studies on tools or methods, which promote the evaporation of the dental adhesives, are needed.
