Good marginal adaptation, marginal integrity or marginal seal is one of the ideal requisites of a restorative material. It has been proved that beveling enamel in occlusal and buccal surfaces of cavity preparations results in a good marginal adaptation and thereby reducing the microleakage. However, the cavo surface finish line of class II cavity preparations has gained only little attention. The aim of the present in vitro study was to compare the microleakage between the tooth and the composite restoration by giving Butt joint, external bevel and Internal bevel. 30 freshly extracted maxillary permanent premolars were selected and stored in saline. They were divided into 3 groups of 10 teeth each according to the bevels at the approximal cavosurface. The restored teeth were then immersed in 0.2% Rhodamine B dye for 24 hours and sectioned in a mesio-distal direction. The teeth were viewed under fluorescent microscope (OlymoysBX40) at 4x magnification and the leakage was evaluated.
