Abstract

In the present in-vitro study, microleakage was evaluated in deep class II composite fillings, restored with three different restorative techniques. Sixty proximal boxes with the gingival margin below the CEJ were cut in extracted posterior teeth and cavities were divided into three equal groups. Restorations were placed as follows. Group 1: Total-etch followed by bonding and incremental placement of nano-composite. Group 2: Resin modified glass ionomer cement as a gingival increment followed by total-etch, bonding and filling with nano-composite in increments. Group 3: Total etch and bonding followed by bulk-fill composite with final increment of nano-composite. Teeth were coated with nail varnish within 1-mm of tooth restorative interface and apices were sealed with sticky wax. Teeth were immersed into 2% aqueous solution of methylene blue dye for 24-hours, washed and sectioned mesio-distally. Dye leakage was studied under stereomicroscope. Statistical analysis was done using SPSS (V17). Descriptive statistics were employed. Result: There was no statistically significant difference in dye leakage scores among the three tested groups.

No technique was successful in arresting the dye leakage at gingival margin.
