520			_aObjectives. To investigate the effect of different bulk filling techniques of resin composite on the development of polymerization stresses at the interface reflected as cuspal deflection and strain developed upon loading within teeth restored by different bulk filling techniques and to measure the effect of such techniques on the curing depth of resin composite. Methods. A standardized MOD cavity was prepared in thirty extracted maxillary premolars of almost similar size. They were divided into three main groups, group A: restored by conventional consistency composite in incremental technique (control group), group B: the cavity was lined with the SDR (flowable bulk filling composite) up to 4mm covered by 2mm of the conventional composite and group C: restored by conventional consistency composite filled in bulk. Cuspal deflections were recorded by measuring the distance between fixed points on the cusps using a universal measuring microscope
