Abstract
Dentinal hypersensitivity (DH) is one of the most painful and least predictably treated chronic conditions in dentistry. Therefore, it is of interest to evaluate the efficacy of 5% sodium fluoride (NaF) varnish, gluma varnish and diode laser and their combined application in treating dentin hypersensitivity. The findings suggest that 5% NaF alone or combined with diode laser significantly reduces the severity of DH. Combinatorial intervention of diode laser with desensitising agents is therapeutically more effective in treating DH than the application of laser, 5% NaF and Gluma alone.
