The article focuses on a study on operative dentistry. It compares leakage at the cervical and occlusal margins after restorations prepared by filling in bulk with leakage prepared by incremental filling. It describes the method and materials used in the study, in which Class II cavities were prepared in extracted molars and premolars. The study revealed that less penetration of dye was seen at the cervical margin of the incremental filling of Class II cavities with a composite resin than with bulk filling. It also revealed that least amount of leakage was seen at the occlusal margin.

    Shrinkage of composite resin during polymerization is responsible for the formation of a microgap at cavity margins that permits the ingress of bacteria and oral fluids. This study investigated four methods of incremental insertion of composite resin into mesio-occlusodistal cavity preparations...
