【 摘 要 】

The aim of the study was to determine the effects of agents toothpastes on the hydraulic conductance of dentin desensitizers "in vitro". We selected 60 third molars healthy humans, recently extracted without occlusal contact, of patients between 15-30 years, which were cleaned, disinfected (Tymol 0.1% per 24 hours) and preserved at T atmosphere solution for a maximum of 14 days. The crowns were sectioned perpendicular to the tooth axis under abundant refrigeration, obtaining a disc of 1 mm +/-0.1 mm. thickness for each Crown. Disks were separated into the following three groups of treatment, of 20 discs each, which were brushings (brush electrical Oral-B Pro health Power) for 2 minutes only by your face occlusal with; a) Colgate® Sensitive Pro relief with technology Pro arginine (Colgate-Palmolive, USA), b) Sensodyne® quick-relief (GlaxoSmitheKline, UK), and c) distilled water as a negative control. The data were statistically analyzed by Kruskall Wallis and Mann Whitney tests. The results expressed in µl*cm−2*min−1cm*H2O−1as stockings, separated by group were; a) 0,00650 (±0.00384), b) 0,00800 (±0,00472), c) 0 and 03649 (±0,03042). You could be concluded with the study that two dentin desensitizers agents present significant decrease in hydraulic conductance in dentin. Statistically significant differences were found between the group control and Sensodyne® fast relief (p = 0,000) and between group control and Colgate® Sensitive Pro relief (p = 0,000). There was no difference between the two toothpastes (p = 0,317).
