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.
