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.
本研究的目的是通过染料渗入根管长度和深层牙本质,评估清洁剂对乳牙本质根管渗透性指数(PI)的作用。数据进行方差分析、F检验和学生t检验(p<0.05)。从纵向来看,1%和2%的洗必泰平均数值显著高于达金氏液。考虑深度,在颈段三分之一处,1%和2%的洗必泰平均数值高于达金氏液加过氧化脲以及达金氏液的平均数值;蒸馏水的平均数值高于达金氏液。在中段和根尖段三分之一处,1%和2%的洗必泰平均数值显著最高。
