The aim of this in vitro study was to compare the percentage of penetration of three final irrigant into the dentinal tubules after application of several irrigation techniques. Mandibular premolars were divided into nine groups (n:10): chlorhexidine (CHX) + conventional syringe irrigation (CI), CHX + EndoActivator (SI), CHX + Er,Cr:YSGG laser (LAI), QMix + CI, QMix + SI, QMix + LAI, Irritrol + CI, Irritrol + SI and Irritrol + LAI. Following irrigation, all roots were horizontally sectioned at 2 mm and 5 mm from the apex and examined using a confocal laser scanning microscopy. QMix exhibited a significantly higher penetration percentage than CHX at the apical section (P < 0.05). In the Irritrol group, SI displayed a significantly higher penetration area than CI in the middle section. Statistically significant differences were also determined between middle and apical section (P < 0.05). Use of QMix with different agitation technique seems advantageous in dentinal tubule penetration.
本体外研究的目的是比较在应用几种冲洗技术后，三种最终冲洗剂渗入牙本质小管的百分比。将下颌前磨牙分为九组（每组n = 10）：洗必泰（CHX）+传统注射器冲洗（CI）、CHX + EndoActivator（SI）、CHX + Er,Cr:YSGG激光（LAI）、QMix + CI、QMix + SI、QMix + LAI、Irritrol + CI、Irritrol + SI和Irritrol + LAI。冲洗后，所有牙根在距根尖2 mm和5 mm处水平切片，并用共聚焦激光扫描显微镜检查。在根尖切片处，QMix的渗入百分比显著高于CHX（P < 0.05）。在Irritrol组中，在中间切片处，SI的渗入面积显著高于CI。中间切片和根尖切片之间也存在统计学显著差异（P < 0.05）。使用QMix并结合不同的搅拌技术似乎在牙本质小管渗入方面具有优势。
