comparison of desensitizing efficacy of an iranian dentifrice and a commercially available dentifrice: a randomized double-blinded controlled clinical trial.

the aim of this randomized controlled clinical trial was to investigate the effect of a new iranian toothpaste and a commercially available toothpaste containing desensitizing agent (5% potassium nitrate) on dentine hypersensitivity in a 24-week study.fifty healthy volunteers, who had at least two sensitive root surfaces, completed the study period. the participants were randomly given one of the two toothpastes; iranian (antihypersensitive pooneh) or commercially available (fresh mint sensodyne) toothpaste. visual analogue scales (vass) indicating the intensity of tooth hypersensitivity responding to tactile, airblast and cold-water stimuli were examined at baseline and weeks 2, 4, 12 and 24.overall, vas scores for tactile, airblast, and cold-water tests significantly reduced compared with the baseline in both groups (all p values <0.001). however, there was no significant difference between the two groups regarding the measured parameters.this study demonstrated that the iranian dentifrice (antihypersensitive pooneh) was as effective as the commercially available one (fresh mint sensodyne) in reducing tooth hypersensitivity.
