To evaluate and compare the microleakage in class five cavities restored by a nano-hybrid and a nano-filled composite resin by dye penetration method.
Twenty premolar teeth were collected and standardized Class five cavities were prepared. The samples were divided into two groups, Group A and Group B. All the samples were then restored with the composite pertaining to that group (n=10). The samples were immersed in 2% methylene blue dye for 24 hours, post which they were sectioned vertically and the microleakage was assessed under the stereomicroscope.
The data for all the samples was obtained and subjected to statistical analysis.
Group B (Nano-filled composite resin) achieved superior results over the nano-hybrid composite resin group and exhibited lesser microleakage.
