Effective root canal treatment relies on the ability of sealers to wet and penetrate the root canal system, ensuring a tight seal and preventing bacterial leakage. The current study investigates the wetting ability of newer root canal sealers by evaluating their contact angle.
The objective of the present study was to evaluate and compare the wetting behavior of Guttaflow bioseal, Ceraseal, and AH plus root canal sealers.
Decoronation and apical third resections of thirty extracted singlerooted human mandibular premolars were done. The roots were then split longitudinally into two halves buccolingually. The root dentin surfaces were treated using 10 mL 3% sodium hypochlorite for 5 min, 10 mL of 17% ethylenediaminetetraacetic acid for 5 min, and 2% chlorhexidine for 10 min. Then, these sixty dentin bars were randomly divided into three groups (n = 20): Group 1 - AH Plus, Group 2 - Ceraseal, and Group 3 - Guttaflow bioseal. The controlled volume of 0.1 mL sealer has been dispensed onto the dentin specimen using a micropipette. The contact angle of a drop of sealer was measured after 5 min using Ossila goniometer.
The data were analyzed using one-way analysis of variance and Tukey post hoc tests. The statistical significance was at < 0.05.
The mean contact angle values for AH Plus sealer were lower when compared to the other two sealer groups which is statistically highly significant.
AH Plus showed lesser contact angle thereby better wettability than Ceraseal and Guttaflow bioseal on the root canal dentin surface.
有效的根管治疗依赖于封闭剂湿润并渗透根管系统的能力，以确保紧密密封并防止细菌渗漏。本研究通过评估新型根管封闭剂的接触角来研究其湿润能力。
本研究的目的是评估和比较Guttaflow生物封闭剂、Ceraseal封闭剂和AH plus根管封闭剂的湿润行为。
对30颗拔除的单根人下颌前磨牙进行去冠和根尖三分之一切除术。然后将牙根沿颊舌向纵向劈成两半。使用10 mL 3%次氯酸钠处理根牙本质表面5分钟，10 mL 17%乙二胺四乙酸处理5分钟，2%氯己定处理10分钟。然后，将这60根牙本质条随机分为三组（n = 20）：第1组 - AH Plus，第2组 - Ceraseal，第3组 - Guttaflow生物封闭剂。使用微量移液器将0.1 mL封闭剂的控制体积滴加到牙本质标本上。5分钟后使用Ossila测角仪测量一滴封闭剂的接触角。
数据采用单因素方差分析和Tukey事后检验进行分析。统计学显著性水平为<0.05。
与其他两组封闭剂相比，AH Plus封闭剂的平均接触角值更低，具有统计学高度显著性。
在根管牙本质表面，AH Plus的接触角较小，因此润湿性比Ceraseal和Guttaflow生物封闭剂更好。
