Author(s): Sura Y Alani and Abdulla MW Al-Shamma*
Introduction: In spite of huge revolution in composite materials and techniques, some drawback still exist which may hindered the success of composite especially in class II restorations such as volumetric shrinkage, micro-leakage and secondary caries. Aims: The purpose of this in vitro study was to evaluate the effects of different placement strategies of bulk fill composites on the gingival micro leakage of class II restorations. Material and methods: forty human extracted premolars teeth had received 2 proximal box preparation with the following criteria (Mesiodistal width: 2 mm, buccolingual width: 3 mm and the gingival margin located 1 mm above CEJ on mesial cavity while for the distal cavity located 1 mm below CEJ. All prepared cavities had received etch and rinse adhesive strategy and had been divided randomly t.. Read More»
