Protocol summary

Summary
The aim of this clinical study is comparative evaluation of two treatment methods including Nd:YAG laser and 40% Propolis gel to improve dentin hypersensitivity (DH) symptoms. 25 patients with DH are selected using simple sampling method. Sensitive teeth of one side are treated with Nd:YAG laser and those of the other side are treated with Propolis gel through split mouth design. The received treatment on each side of the Patients' mouth, will be determined through random numbers table. 12 patients receive laser treatment for their sensitive teeth in right side and propolis gel for their sensitive teeth in left side; and 13 patients contrariwise. Each patient receives three sessions with one week interval and is finally followed up by a blind specialist after one and three month. A Visual Analog Scale (VAS) is used to assess the amount of sensitivity at baseline, during and after treatment. Simulation of opposite side treatment in each side is in this way that fiber tip of laser device is held in off state in propolis treatment side with same time of laser treatment side and just the beep sound of device can be heard. Also the use of wet micro brush without impregnating with propolis in laser treatment side simulates the propolis application. So the study is carried out in double-blind situation. Inclusion criteria are having at least two hypersensitive teeth in two sides of mouth, no periodontal surgery within last 3 months and no desensitizing therapy within last 1 month. Patients who do not participate in all sessions are removed from this study. Finally the effect of tow treatments in decreasing DH will be compared.

Other design features
Randomization is done using random numbers table to determine the kind of treatment in right or left side of patients' mouth. Therefore some patients receive laser treatment in right and Propolis gel in left side, and other patients receive conversely treatment. Because of one type treatment on right sensitive teeth and one other type on left sensitive teeth in each patient, this design study is called split mouth.
