Comparison of the Adhesive Strength of Universal Systems with and without MDP on Dentin by Microblading

Abstract

In dentistry today, evaluating adhesive strength is crucial for successful treatment with universal adhesive systems. This article evaluates the adhesive resistance to dentin micro bleaching of two universal adhesive systems with and without MDP. For this purpose, third molars (n=40), divided into two groups, were used without occlusal enamel using a low-speed bioactive diamond disc with cooling up to 4mm above the amelocemental line. The universal adhesive system with MDP was applied for group 1 (n=20), and the universal adhesive system without MDP for group 2 (n=20). A standardized resin cylinder of 2mm in diameter and 4mm in height was made for both groups using a silicone mold, placing it on the occlusal surface. Each group was divided into two subgroups, where (n=10) were subjected to thermocycling and (n=10) were not subjected to thermocycling, to subsequently perform the micro-shearing test using the Shimadzu AGS-X Universal Testing Machine. The data were analyzed by ANOVA test, stating that the groups with MDP showed significantly higher micro-shear values than those without MDP. This shows that the MDP group's mean shear load value of the resin cylinders is higher than that in the non-MDP group.
