Evaluation of Sensitivity With and Without Sonic Activation of a Desensitizing Gel Before in Office Bleaching in Adults

Dentin Sensitivity Clinical Trial

Official title:
Sensitivity Absolute Risk Evaluation With and Without Sonic Activation of a Desensitizing Gel Previously to in Office Bleaching in Adults.

Clinical Trial Summary

This randomized, controlled clinical trial, triple-blind, split-mouth type was conducted aiming to assess the absolute risk of sensitivity with and without sonic activation of a desensitizing gel previously to the in-office bleaching in adults.

Clinical Trial Description

This clinical trial evaluated the effect of sonic activation of a desensitizing gel on the occurrence of sensitivity associated with office bleaching. For this, 31 patients had their anterior superior teeth divided into right and left, according to the sonic activation (AS) or not (SS) of the desensitizer. Prior to bleaching, a desensitizing gel containing 5% potassium nitrate and 2% sodium fluoride (Desensibilize KF2%, FGM Dental Products,SC, Brazil) was applied. Sonic activation was performed with a sonic device (Smart, FGM Dental Products, SC, Brazil) at the 170 MHz frequency. A hydrogen peroxide gel (Whiteness HP Maxx, FGM Dental Products, SC, Brazil) was used in two whitening sessions. It was also performed, evaluation of the presence of cracks in enamel, through transillumination. The color change was verified using two color scales and a spectrophotometer. The dental sensitivity was recorded through a sensitivity diary answered by the patient, in the period up to 48 hours after each bleaching session. The absolute risk of tooth sensitivity was compared using the McNemar test (= 5%). The color change was analyzed from the variation of units of scale vita (SGU) and through the value of ΔE, which were compared through Student t test (α = 5%). ;
