Abstract

This study was done to determine the possible number of repair that can be carried
out on the same light-cured microfilled composite resin (Helioprogress, vivadent,
Germany). 40 specimens were prepared, stored in deionized distilled water at 37°C
for 24 hours and divided into 4 groups.
Group 1: The repair procedure done once.
Group 2: The repair procedure done twice.
Group 3: The repair procedure done for three times.
Group 4: The repair procedure done for four times.
All the specimens stored in deionized distilled water at 37°C for 24 hours before
testing. A universal zwick testing machine with a special designed chisel was used to
evaluate the shear bond strength of the repaired composite resin. The results showed
reduction in mean shear bond strength value from group 1 to group 4, furthermore a
significant difference was found between group 1 Vs group 3 and group 1 Vs group 4.
