In vitro assessment of bonding of the total-etch adhesive to carious dentin in molars treated with and without 38% silver diamine fluoride: a study protocol

Abstract

Background: The aim will be to evaluate and compare the bonding of the total-etch adhesive to carious dentin in molars treated with and without 38% silver diamine fluoride using the universal testing machine and scanning electron microscope. Methods: 30 extracted teeth samples will be been randomly distributed into 2 groups (n=15). The test group will receive the intervention of 38% SDF whereas the control group will not receive any such intervention. Samples in both groups will be restored with resin composite. Assessment will be done based on the primary outcome, which will be determined by microtensile bond strength whereas the secondary outcome will be determined by fracture modes, i.e., cohesive, adhesive, or mixed fracture. Descriptive statistics will be used for the results of each group. Intergroup comparison will be done on the basis of independent sample t-test to detect the mean difference between the two groups. Independent t-test will be run to analyse the type of failure. In all tests, p-values below 0.05 will be considered statistically significant. Conclusion: The study may provide us with a new restorative technique that will not only be less invasive by preserving the remaining tooth structure but will also prevent the risk of caries progression beneath the restoration. Thus, this will contribute to the longevity of the tooth life by the maintenance of its pulpal health which will contribute to the durability and long-term successful outcome of the direct restoration procedure.
