Abstract
The purpose of this study was to evaluate flexure strength of composite resin inlay according to heat treatment and duration in comparasion with visible light-cured resin.
In this study, materials were used 1 visible light-cured resin and 3 kinds of composite resin inlays.
Control group was visible light cured resin(Photo Clearfil Posterior) and experimental group were composite resin inlays (Brilliant Dentin, Brilliant Enamel and Clearfil CR Inlay).
Experimental groups were divided 3 groups:
First group was Brilliant Dentin and second group was Brilliant Enamel and third group was Clearfil CR Inlay.
Used experimental groups were calculated flexural strength according to heat treatment and duration.
@ES The following results were obtained:
@EN 1. Experimental groups were higher flexural strength than control group.
2. At 100°C when heat treatment carried out 7 minutes flexural strength elevated third group, second group, first group in turn and when heat treatment carried out 15 minutes flexural strength elevated third group, second group, first group in
turn
but no difference was showed between first and second group.
3. At 125°C when heat treatment was carried out 7 minutes flexural strength elevated third group, second group, first group in turn and when heat treatment was carried out 15 minutes flexural strength elevated third group, first group, second
group in
turn but no difference was showed between first and second group.
4. In spite of heat treatment and duration the third group was highest flexural strength in the others groups.
