The aim of this study was to determine the effect of low dose nz660 and nm810 lasersdiod in treatment of dentinal hypersensitivity in a double-blind randomized clinical trial. Patients with cervical dentin hypersensitivity were included in the study, and smokers or rotten teeth were excluded from the study. In order to record the pain intensity of 96 dentin hypersensitivity teeth in 7 patients, the male and female entered the study based on entry and exit criteria, stimulation was performed using dry ice spray on a swab and VAS index, and the compliance was based on the primary VAS of the teeth And then a randomization took place. The sensitive teeth of each patient were entered into one of the groups: 660 nm diode lasers, 810 nm diode lasers and the control group. Each patient's teeth were grouped in order to apply each of the three groups in each patient, then the 660 nm laser diode with a power of 30 mW and 810 nm with a power of 100 mW and both 120 seconds continuous and return and return in the sensitive areas of radiation Given. Blind laser radiation simulation was used in Blind Control group. Evaluation of pain before and after all four sessions of laser treatment that lasted for one week, one week, 30 days and 60 days after the end of treatment by VAS method.
