Abstract
The study investigated the clinical performance of two posterior composite restorative materials in class I and class II restorations over a period of 6 months. 25 patients were selected randomly from the out patients coming to department. Written patient consent was obtained at the start of procedure. The composite restorative materials tested were Ceram-X Duo (Dentsply Detrey) and Heliomolar (Ivoclar Vivadent). Class I and class II restorations were performed by a single operator using adhesive preparation design with no margin beveling. Only small to moderate cavities were included in the study. All the restoration were evaluated using United States Public Health Services (USPHS) criteria at baseline and there after at an interval of 1, 3 and 6 months by two investigators independently. Changes in the parameters during the 6 month period were evaluated using Friedman test. No statistical significance was found between the two materials regarding any of the parameters tested over a period of 6 months. But clinically significant difference was found between the two materials. Ceram-X showed clinically better results than Heliomolar.
