| Summary: | Background: The study was planned to assess the use of
low shrinkage composites for restoring cavities with high
configuration factor (C-factor) which are subjected to high
stresses.
Aim: The aim of the study was to evaluate the effect of C- factor
on tensile bond strength to human dentin using methacrylate
based nanohybrid and low shrinkage silorane composite.
Materials and Methods: In this study 40 non carious human
molar teeth were selected and assigned into two main groups
- cavity (Class I cavity with high C-factor) and flat group (flat
surface with low C-factor). Two different composite materialsmethacrylate based and silorane low shrinkage composite were
used to restore the teeth. Dentin surface was treated, adhesive
application was done and composite was applied as per
manufacturer’s instructions. Samples were stored in distilled
water then subjected to tensile bond strength measurement
using universal testing machine.
Results: Statistical analysis was done using Independent sample
t-test. The mean bond strength in methacrylate based and
silorane composite was significantly higher in flat preparation
(Low C-factor) than cavity preparation. The mean bond strength
in both cavity (High C-factor) and flat preparation(Low C-factor)
was significantly higher in silorane than in conventional
methacrylate based composite.
Conclusion: The bond strength of composites to dentin is
strongly influenced by C-factor and type of composite resin
material used. |
