本研究的目的是评估四种不同的最终灌溉制度后的副管封闭情况。拔除的人下前磨牙64颗，随机分为4组，最后冲洗：不冲洗（no）、蒸馏水（WA）、次氯酸钠（[SH] 6%, 20 ml, 15 min）、EDTA （15%, 8 ml, 3 min）联合SH方案（ES）。系统B和Obtura II被用来填充运河。清除牙齿，在数码显微镜下观察。测量封闭材料在副管中的长度渗透率，结果如下：NO组22.3%，WA组21.8%，SH组53.5%，ES组68.1%。前两组（NO、WA）与SH、ES组比较，差异均有统计学意义（p < 0.05）。在最后冲洗时单独使用次氯酸钠或与EDTA联合使用可使封闭材料更好地渗透到附属管中。
The aim of this study was to evaluate accessory canal obturation after four different final irrigation regimes. Sixty-four extracted human lower premolars were instrumented, divided randomly into four groups, and finally irrigated as follows: no irrigation (NO), distilled water (WA), sodium hypochlorite ([SH] 6%, 20 ml for 15 min), and EDTA (15%, 8 ml for 3 min) combined with the SH regimen (ES). The System B and the Obtura II were used to fill the canals. The teeth were cleared and observed under a digital microscope. Obturation material penetration rates in length into the accessory canals were measured and the following values were obtained: 22.3% in group NO, 21.8% in group WA, 53.5% and 68.1% in groups SH and ES, respectively. Statistically significant differences were found when comparing each of the first two groups (NO and WA) with SH and ES groups (p < 0.05). The use of sodium hypochlorite alone or in combination with EDTA in final irrigation flushes may enhance a better obturation material penetration into the accessory canals.
