Evaluation of Effect of 10% Papain on the Shear Bond Strength of Resin-modified Glass Ionomer Cement, Single-step Composite and Transbond XT: An In Vitro Study

Objective The research purpose was to inspect the impact of deproteinization of enamel through the use of 10% papain on the shear bond strength (SBS) of resin-modified glass ionomer cement (RMGIC) and single-step composite (Biofix), and compare it with the regularly used composite bonding material (Transbond XT). Methodology Extracted premolars (120) were equally separated into four groups. Group A (RMGIC + papain), Group B (Biofix + papain), Group C (Transbond XT + papain), and Group D (Control) (Transbond XT without papain). The SBS and adhesive remnant index (ARI) were studied and juxtaposed. Results There were statistically significant differences ( P < .01) observed in mean SBS values among all groups. According to the study results, the mean SBS value of Group C (12.77 + 3.13 MPa) was statistically more than that of the other groups ( P < .01). Although, differences in values among Groups A (8.55 + 3.61 MPa), B (7.44 + 2.34 MPa), and D (9.71 + 4.19 MPa) were not significantly different ( P > .05). The study did not find any relevant difference in the mean ARI scores between all groups ( P > .05). Conclusion Deproteinization with the use of 10% papain has significantly improved the SBS values of RMGIC and Biofix. Making these materials comparable to conventional composite.
