title: Marginal microleakage around enamel and cementum surfaces of two compomers.
abstract: The purpose of this study was to evaluate the marginal microleakage of two compomers, placed in enamel and cementum. The buccal and lingual surfaces of twenty human premolar teeth were used. Materials used were Dyract and Compoglass. Teeth were randomly divided into 4 groups of 5 teeth each. Materials were handled according to the instructions of the manufacturer. Class V cavities were prepared with enamel and cementum margins. The groups with etched surfaces was done using 37% phosphoric acid. Two percent fuchsin was used for microleakage study. Results were evaluated using an analysis of ANOVA. These showed that microleakage in enamel was significantly less than in cementum. No significant differences in microleakage were seen between the two materials or between etched and unetched surfaces.
