The evaluation of microleakage in posterior composite restoration

The aim of this study is to evaluate the ability of composite resin to reduce microleakage by release of ions like Ariston pHc and Tetric ceram composite. 72 Cl V cavity were prepared in 36 teeth (extracted upper first premolar), one buccally and one palatally in each tooth, the cavities were loc...
