简要总结
This study investigated the effects of the association of strontium chloride with photobiomodulation on the dental bleaching process, testing the hypothesis that they may control dental sensitivity post-bleaching teeth.
详细描述
The objective of this double-blind, randomized, controlled clinical study was to evaluate the effect of 10% strontium chloride associated with photobiomodulation (FBM) on teeth exposed to 35% hydrogen peroxide during 3 weeks of whitening treatment. Methods: 50 volunteers were evaluated by the split mouth model, where the hemiarchy patients were randomized and subsequently allocated to one of the experimental groups: PLACEBO (negative control) - group with no desensitizing treatment, only bleached; FBM (positive control) - group treated with placebo gel and application of the LLLT (Low Level Laser Therapy); ESTRÔNCIO (positive control) - group treated with 10% strontium chloride and simulation of LLLT application (without light emission); and FBM + ESTRÔNCIO - group treated with LLLT + 10% strontium chloride.

主要结局
Efficacy of desensitizer treatment in the control of tooth post-bleaching sensitivity (P21)
时间窗: 21 days
Self-reported pain intensity was assessed daily, during 21 days, through self-perception questionnaire, answered by the patients from the first tooth bleaching session until one week after the last session. The evaluation was performed by each patient, according to a modified visual analog scale, as follows: 0- no pain, 1 mild pain, 2 - moderate pain and 3 -severe pain.
