Abstract

This double-blind randomized clinical trial assessed the Nd:YAG laser and calcium sodium phosphosilicate (NovaMin®) prophy paste effect in the treatment of cervical dentin hypersensitivity (CDH). The study consisted on three experimental groups: 1. Control-placebo, 2. calcium sodium phosphosilicate prophy paste - NovaMin® and 3. Nd:YAG Laser (1W, 10Hz, 85J/cm²). Pain was evaluated through a visual analogue scale (VAS) after evaporative stimuli with air blast and tactile stimuli with exploratory probe at baseline and after 5 minutes, 1 and 4 weeks. A simple mean was calculated for each patient, using individual results. Nd:YAG laser was irradiated twice at mesio-distal direction and twice at occluso-gingival direction. Prophylaxis using NovaMin® was performed 60 seconds after paste was applied. Patients from control group received each treatment simulation. Both patients and evaluators did not know the administered treatment, as the principal researcher were blinded to the pain results. The data presented normal distribution and ANOVA for repeated measures with 2 factors was used. There was no significant differences between groups (p>0,05) and all groups presented decreased pain levels after treatments. All the treatments were equally efficient in decrease pain related to CDH. (AU)
