The aim of this paper was to evaluate the intratubular penetration area of a bioceramic sealer, using continuous wave (CW), vertical condensation (VC) with two different types of gutta-percha (conventional (NG) and bioceramic-coated (BG)) and single cone (SC) technique with BG gutta-percha, in different root thirds.
A total of 150 mature single-root human teeth (including incisors, canines and premolars) were prepared and randomly divided into five groups (n = 30). Teeth were filled using a bioceramic sealer (TotalFill BC Sealer HiFlow ®) and two different types of gutta-percha, with CW and VC techniques, the teeth in the control group were filled with SC technique and BG gutta-percha. The teeth were sectioned and evaluated as one-third portions in each case under a confocal laser microscope. The penetration area measurements were carried out with the Autocad ® programme. Data was analyzed using the one-factor ANOVA test (p < 0.05) and Post Hoc Test (p < 0.05).
The ANOVA Test showed significant differences in the penetration areas of the five obturation techniques (P < 0.05). The Post Hoc Test exhibited significant differences in multiple comparisons (P < 0.05). There was more dentinal tubule penetration in the coronal third than in the apical third in all techniques.
The intratubular penetration of the bioceramic sealer was influenced by the obturation techniques tested, but not by the different gutta-percha tested. There was more penetration of sealer in the warm obturation techniques than the SC, regardless of the type of gutta-percha used.
本文旨在评估一种生物陶瓷封闭剂在不同牙根三分之一处，使用连续波（CW）、垂直加压（VC）两种不同类型的牙胶（传统牙胶（NG）和生物陶瓷涂层牙胶（BG））以及单尖法（SC）结合BG牙胶时的根管内渗透面积。
共准备150颗成熟的单根人牙（包括切牙、尖牙和前磨牙），随机分为五组（n = 30）。使用生物陶瓷封闭剂（TotalFill BC Sealer HiFlow®）和两种不同类型的牙胶，采用CW和VC技术对牙齿进行充填，对照组牙齿采用SC技术和BG牙胶进行充填。将牙齿切片，在共聚焦激光显微镜下分别作为三分之一部分进行评估。使用Autocad®程序进行渗透面积测量。数据采用单因素方差分析（p < 0.05）和事后检验（p < 0.05）进行分析。
方差分析显示五种充填技术的渗透面积存在显著差异（P < 0.05）。事后检验在多重比较中显示出显著差异（P < 0.05）。在所有技术中，冠三分之一处的牙本质小管渗透比根尖三分之一处更多。
生物陶瓷封闭剂的根管内渗透受到所测试的充填技术的影响，但不受所测试的不同牙胶的影响。无论使用何种类型的牙胶，热充填技术中封闭剂的渗透都比单尖法更多。
