Abstract
|
|
|
Purpose: The Purpose of this study is to compare the fracture strength of 4 kinds of direct composite resins.
Methods: his study performed experiments on the fracture strength of direct composite resins after polymerizing 4 kinds of direct composite resins on the MOD cavity standard specimens.
Results: The fracture strength of Aelite(Bisco) was the highest at 176.26N(p＜0.05). According to post-hoc study with Turkey honest significant difference by multiple comparison on fracture strength test results, there were statistically significant differences between all kinds of direct composite resin. But the statistical difference between Z350(3M) and Spectrum(DP) was not significant.
Conclusion: Aelite(Bisco) scored the highest concerning the fracture strength.
