The effects of different obturation techniques on calcium silicate‐based sealer penetration in the presence of apically separated rotary files were evaluated. Forty‐eight extracted mandibular incisors were used. ProTaper F2 rotary files were separated at the apical thirds. Samples were divided into four groups (n = 12) according to obturation technique used: (a) cold lateral compaction (CLC); (b) single cone; (c) bulk‐fill (BF) without a core material; and (d) thermoplastic injection (TI). Specimens were sectioned horizontally at 1 and 3 mm from the apex and studied using a confocal scanning laser microscope. The maximum tubule penetration depth and percentage of penetration were measured. Data were statistically analyzed using parametric and nonparametric tests with a significance level of 5%. Regarding penetration depth, a significant difference was found at 1 mm (p < .05), while no significant difference was found at 3 mm (p > .05). At the 3 mm level, all of the obturation techniques showed similar penetration depths. Regarding penetration percentage, the values of the CLC and TI groups were statistically less when compared with the BF group at 1 and 3 mm levels, respectively (p < .05). Under the limitations of this in vitro study, results suggest that the obturation technique may present a significant effect on sealer penetration.

与顶端分离的旋转镍钛仪器一起使用的不同封闭方法对封闭剂渗透的影响：共聚焦激光扫描显微镜研究。

评估了在根尖分离的旋转锉存在下，不同封闭技术对硅酸钙基封闭剂渗透的影响。使用四十八颗下颌切牙。ProTaper F2旋转锉刀的顶端分开了三分之二。样本分为四组（n= 12）根据所使用的密闭技术：（a）横向冷压实（CLC）；（b）单锥；（c）不使用芯材的散装填料（BF）；（d）热塑性注射剂（TI）。将标本在距顶点1毫米和3毫米处水平切片，并使用共聚焦扫描激光显微镜进行研究。测量最大小管穿透深度和穿透百分比。使用显着性水平为5％的参数和非参数检验对数据进行统计分析。关于穿透深度，在1 mm（p <.05）处发现显着差异，而在3 mm（p> .05）。在3 mm的水平上，所有封闭技术均显示出相似的穿透深度。关于渗透率，与BF组相比，分别在1和3 mm的水平上，CLC和TI组的值在统计学上较小（p <.05）。在这项体外研究的局限性下，结果表明封闭技术可能对封闭剂的渗透产生重大影响。
