Can pulpal floor debonding be detected from occlusal surface displacement in composite restorations?
Polymerization shrinkage of resin composite restorations can cause debonding at the tooth –restoration interface. Theory based on the mechanics of materials predicts that debonding at the pulpal floor would half the shrinkage displacement at the occlusal surface. The aim of this study is to test this theory and to examine the possibility of detecting subsurface resin composite restorat ion debonding by measuring the superficial shrinkage displacements.
