Online published on 3 April, 2018. 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. Top Keywords Microleakage, Stereomicroscope, Dentin. Top |
