EVALUATION OF MICROTENSILE BOND STRENGTH OF COMPOSITE RESIN WITH DIFFERENT BONDING AGENTS ON ETCHED DENTIN TREATED WITH BROMELAIN AND PAPAIN: AN INVITRO STUDY

Aim: Using various bonding substances, the purpose of this research is to evaluate as well as contrast the effects of 10% bromelain and papain on the microtensile durability produced by composite resin when applied to etched dentin. Current resea Material and methodology: rch was conducted on 30 human permanent mandibular molar teeth. Disto-occlusal & Mesio-occlusal conservative cavities were prepared, etchant application was done for 15 seconds and rinsed with water and blot dried. Prepared samples randomly split into 2 groups/categories (n=15) depending on the deproteinization agent used. (G1):10% Bromelain for 1 min. (G2):10% Papain (1 min) and then washed off. MO cavities treated using Prime Bond NT bonding agent & DO cavities treated using Adper Single-Bond 2 bonding agent and restored with bulkll composite (TetricN-Ceram) and the samples subjected to thermocycling. Samples then sectioned vertically into 1mm2 thick slabs by using hard tissue microtome and were subjected to universal testing machine for analysis of the durability of the microtensile bond. The software SPSS Statistical analysis: version 20 (IBM, SPSS, Armonk, NY, USA) was used to conduct the statistical analysis. Data evaluation techniques include descriptive statistics and a single direction assessment of deviation using Tukey's post-hoc testing. With a microtensile b Results: ond strength of 58.14±1.97 MPa, Group 1 (Bromelain-MO) showed highest microtensile bond strength and Group 4 (Papain-DO) 21.92±2.86 MPa has the least microtensile bond strength. The microtensile bond strength varied between the two groups in a statistically signicant. Every pairwise comparison shown to be statistically signicant by Tukey's post hoc testing. : The mean microtensile bond strength values o Conclusion f bromelain treated with Prime bond NT and Adper single bond 2 was signicantly high in comparision to papain treated with Prime bond NT and Adper single bond 2.
