摘要

目的:本研究评估2.5%次氯酸钠(NaOCl)在有准备和没有准备以及不同冲洗激活方案的情况下在根管内的牙本质渗透深度。材料与方法:63只牛下颚切牙随机分为6组(n = 10): G1组,制剂+常规针灌(CNI);G2,制剂+被动超声灌洗(PUI);G3,制剂+ Odous Clean (OC);G4,无制备+ CNI;G5,无准备+ PUI;G6,无制剂+ OC;CG(阴性对照);n = 3)。样品用结晶紫填充72小时。进行灌溉激活。样品沿长轴垂直切片,分别距顶点3mm和7mm。用立体显微镜捕获每个块根三分之一的图像,并用图像分析软件进行分析。数据分析采用单因素方差分析,随后采用Tukey事后检验和学生t检验,显著性水平为5%。结果:无论灌洗激活方式如何,制备时NaOCl的渗透深度相似(p > 0.05)。未预处理组中,G6的NaOCl渗透深度较大(p < 0.05)。未制备组的NaOCl穿透深度大于制备组(p = 0.0019)。结论:NaOCl在根管预备组的渗透深度相近。在没有根管准备的情况下,OC允许更深的NaOCl渗透。未预备组的NaOCl渗透性高于预备组。

Dentinal tubule penetration of sodium hypochlorite in root canals with and without mechanical preparation and different irrigant activation methods.

Dentinal tubule penetration of sodium hypochlorite in root canals with and without mechanical preparation and different irrigant activation methods.

Dentinal tubule penetration of sodium hypochlorite in root canals with and without mechanical preparation and different irrigant activation methods.

Dentinal tubule penetration of sodium hypochlorite in root canals with and without mechanical preparation and different irrigant activation methods.

Objectives: This study evaluated the dentinal penetration depth of 2.5% sodium hypochlorite (NaOCl) in root canals with and without preparation and different irrigant activation protocols.

Materials and methods: Sixty-three bovine mandibular incisors were randomly allocated to 6 groups (n = 10): G1, preparation + conventional needle irrigation (CNI); G2, preparation + passive ultrasonic irrigation (PUI); G3, preparation + Odous Clean (OC); G4, no preparation + CNI; G5, no preparation + PUI; G6, no preparation + OC; and CG (negative control; n = 3). Samples were filled with crystal violet for 72 hours. Irrigant activation was performed. Samples were sectioned perpendicularly along the long axis, 3 mm and 7 mm from the apex. Images of the root thirds of each block were captured with a stereomicroscope and analyzed with an image analysis software. One-way analysis of variance, followed by the Tukey post hoc test, and the Student's t-test were used for data analysis, with a significance level of 5%.

Results: The NaOCl penetration depth was similar when preparation was performed, regardless of the method of irrigation activation (p > 0.05). In the groups without preparation, G6 showed greater NaOCl penetration depth (p < 0.05). The groups without preparation had a greater NaOCl penetration depth than those with preparation (p = 0.0019).

Conclusions: The NaOCl penetration depth was similar in groups with root canal preparation. Without root canal preparation, OC allowed deeper NaOCl penetration. The groups without preparation had greater NaOCl penetration than those undergoing root canal preparation.
