Effectiveness of Resin-Based Desensitizer and Laser, Compared to Fluoride Varnish in Management of Dentine Hypersensitivity in Non-carious Cervical Lesions

84 patients who fulfill the inclusion criteria will be enrolled to the study. For every patient a tooth of complain which fulfill the inclusion criteria will be selected, so the total number of included teeth will be 84 teeth. Teeth will be classified into 4 groups according to the type of desensitizer used. Where in group 1 (G1) patients will be randomly assigned to "Resin-Based Desensitizer", in group 2 (G2) patients will be randomly assigned to "Laser Desensitizer", in group 3 (G3) patients will be randomly assigned to "Combination of Laser + Resin-Based Desensitizer", and in group 4 (G4) patients will be randomly assigned to "Fluoride-Based Desensitizer". For every patient, sensitivity test will be done using visual analogue scale immediately after application, three months after application and six months after application. Table 1 shows the variables of the study, and Table 2 shows the variables of the study. Each patient's name will be replaced with a case number within the group to protect the privacy of medical information and data of the patients.
