Efficacy of dentin bio-modification with quercetin-bromelain on shear bond strength of teeth restored with MICR technique

: Dentin biomodification with natural extracts is done to improvise the bond strength with chemomechanical caries removal technique To evaluate and compare the efficacy of dentin bio-modification with quercetin-bromelain on SBS of teeth restored with Minimal Invasive Caries Removal (MICR) technique 48 extracted teeth with class I dentinal caries were divided into 2 followed by subdivided into 2 subgroups in each group (n=12). Group1: Without dentin biomodification Caries removal done with No.4 round bur (1a) & V-carie-solve (1b) Group2: With dentin biomodification (Quercetin-Bromelain) Caries removal done with No.4 round bur (2a) & V-carie-solve (2b) followed by dentin biomodification After composite restoration, samples were subjected to immediate SBS analysis. Two samples were examined under SEM from each subgroup. : Kruskal Wallis test with Bonferroni’s correction for multiple tests was used to assess the mean difference between the groups. : Dentin biomodification with mechanical and MICR technique showed better bond strength. Dentin biomodification with mechanical caries removal showed highest SBS. : Dentin bio-modification with Quercetin-Bromelain could improve bond strength with MICR technique.
