Preliminary Histopathological Study of a New Quartz-Filled Composite Dental Restorative Material

Abstract

An experimental composite dental restorative material was studied histologically by means of restorations, with and without cavity liners, in the teeth of rhesus monkeys. A commercially available composite material, with liner, was used for comparison. There was a definite, statistically significant, downward trend of pulpal response with time for all materials tested, although there was no significant difference among them. The experimental restorative appeared to produce no more pulpal response without a liner than when liners were used.
