Abstract :
Aim: The objective of this study was to compare the micro leakage in Class I cavity preparations restored with different tooth colored materials.
Materials and Method: Standardized Class I cavity were made in 30 human premolar teeth. Specimens were randomly divided into four groups comprising of 10 samples each (n=10). Group I: Teeth were without any restorative material (Control). Group II: Restored with a nano ionomer, Group III: Restored with a silorane composite, Group IV: Restored with SDR. All specimens were immersed in 2% methylene blue dye. The specimens were sectioned and evaluated for microleakage under stereomicroscope.
Results: Group IV (SDR) showed lesser microleakage than P90 followed by Ketac N100.
Conclusion: It was concluded that SDR (Smart Dentin Replacement) had the lowest level of micro leakage amongst all the groups.
