Effect Of Two Different Composites On Gingival Microleakage Of Class Ii Restoration Using Four Different Placement Techniques (An In Vitro Study)
Objective: To determine the effect of two different composite resins by using different filling techniques through measuring the gingival microleakage in class II cavity. Materials and methods: Standardized 80 class II cavities were prepared in the proximal surfaces of forty extracted non caries permanent molars and randomly were divided into two main groups (A and B) 40 cavities for each group.
