The influence of cleansers on the permeability index of primary tooth root dentin.
The aim of this study was to evaluate the action of cleansers on the permeability index (PI) in the root canal of primary dentin, by dye penetration into the length of the root canal and deep dentin. The data were submitted to ANOVA, F, and Student t tests (p<0.05). Lengthwise, chlorhexidine 1% and 2% presented significantly higher mean values than Dakin's liquid. Considering depth, in the cervical third, chlorhexidine 1% and 2% mean values were higher than Dakin's liquid+urea peroxide and Dakin's liquid mean values; distilled water mean values were higher than Dakin's liquid. In the middle and apical thirds, chlorhexidine 1% and 2% mean values were significantly the highest.
