| Abstract |
|
The purpose of this study was to evaluate the effect of collagenase and esterase on the microtensile bond strength(㎕TBS) in dentin bonding. After resin composites were bonded to occlusal dentin. ㎕TBS specimens were formed and stored in PBS, collagenase, or esterase solution After 4-week storage, ㎕TBS was determined and, the results were as follows : 1. ㎕TBS values of Single Bond 2 were lower than those of Clearfil SE Bond for all storage medium (p<0.05). 2. In Single Bond 2 group, collagenase solution lowered bond strength more than PBS and esterase solution (p>0.05). 3. In Clearfil SE Bond group, esterase solution lowered bond strength more than PBS(p>0.05). Collagenase solution lowered bond strength more than esterase solution(p>0.05) and PBS(p<0.05). |
