To evaluate and compare the marginal leakage in class V cavities restored with three different tooth colored restorative materials using dye penetration system.
Thirty extracted premolars were randomly selected for this study. Standardized classV cavities were prepared and then divided into three equal groups. Group I was restored with nano filled composite, Group II was restored with hybrid composite and group III with polyacid modified composite. They were then subjected to thermo cycling, immersed in 2% methylene blue dye, sectioned and examined under stereomicroscope. Dye penetration for each section was recorded and data was analyzed.
Lowest micrileakage was recorded in group I and highest leakage recorded in Group III.
Nanofilled composite resins provide a better sealing than hybrid and polyacid modified composites.
