Abstrakt:	Aim: To determine the effect of three different dentin hypersensitivity treatment procedures on the microtensile bond strength of etch and rinse and self-etch adhesive system. Materials and Methods: Eighty extracted intact human permanent lower premolars were decoronated, and dentin was exposed on the buccal surface. The teeth were randomly assigned to two experimental groups of 40 teeth each: etch and rinse system or self-etch system. The 40 samples assigned were further randomly assigned to four desensitizing treatment subgroups: Control, Gluma, NovaMin, and GC tooth Mousse with 10 samples per subgroup. Desensitizing treatment was performed two times each day for 2 weeks respectively. The exposed dentin was subjected to etch and rinse or self-etch adhesive system bonding agent as per the group and restored using composite to 4-mm thickness. Samples were then subjected to universal testing machine for microtensile bond strength. Results: The bond strength to the dentin obtained with etch and rinse adhesive system group where significantly higher ( P < 0.05) when compared to self-etch adhesive system. However, there was no significant effect of the desensitizing agent on the microtensile bond strength in its own. Scanning electron microscope imaging reviled tubular occlusion in all specimens treated with desensitizer. Conclusion: The bond strength was majorly impacted by the type of adhesive system used. While the desensitizing agents used in the study had little or no adverse effect on the bond strength of composites to dentin surface. Competing Interests: There are no conflicts of interest.
