Conservative Class-II (MOD) preparations were made in 30 extracted human molars with one proximogingival margin on enamel and the others on cementum. All the preparations were restored with the same composite material utilizing bulk, horizontal, and oblique incremental insertion method and the teeth were sectioned and evaluated for dye penetration with standardized method. The purpose of this study is to compare the marginal leakage of class-II Light cured composite resin restorations with different insertion techniques.
