Obturation of the root canal is the most critical step in endodontic treatment, which aims to provide a hermetic seal and prevent regrowth and entry of bacteria into the canal. To achieve this, many sealers are used in endodontics.
To evaluate the effectiveness of the apical seal obtained by different sealers used in conjunction with the single cone obturation technique using gutta-percha under the stereomicroscope.
Extracted human single-rooted teeth were taken and decoronated at the cementoenamel junction. The access cavity was prepared, and biomechanical preparation was completed. The samples were randomly assigned to four groups consisting of 20 teeth each according to the root canal sealer used and categorized as group I, group II, group III, and group IV. Group I ( = 20)-Endoseal (Prevest DenPro), group II ( = 20)-Apexit Plus (Ivoclar Vivadent), group III ( = 20)-MTA-FillApex (Angelus), and group IV ( = 20)-Ceraseal (Meta Biomed). The teeth were immersed in Indian ink for 7 days and finally transferred to methyl salicylate for diaphanization. The extent of dye penetration was measured using the stereomicroscope. Statistical data analysis was performed using analysis of variance (ANOVA) and the Tukey test.
Microleakage was seen in all the groups. Apical leakage was maximum for the Endoseal group, followed by MTA Fillapex, Apexit, and Ceraseal. Groups were compared by one-factor ANOVA, and the significance of the mean difference was measured using Tukey's honestly significant difference (HSD) and test. A statistically significant difference in the depth of dye penetration was observed among the groups ( = 28.66, < 0.001).
It was concluded that there were statistically significant differences among the experimental groups. Ceraseal endodontic root canal sealer provided a significantly better apical seal, followed by Apexit and MTA Fillapex, whereas Endoseal showed the least sealing ability.

根管充填是牙髓病治疗中最关键的步骤，其目的是提供一个密封环境，防止细菌再生长和进入根管。为实现这一目标，牙髓病学中使用了多种封闭剂。
在体视显微镜下评估不同封闭剂与使用牙胶的单锥充填技术联合使用时获得的根尖封闭效果。
收集拔除的人类单根牙，并在牙骨质釉质界处截冠。制备进入腔，完成生物力学预备。根据所使用的根管封闭剂，将样本随机分为四组，每组20颗牙，分别为I组、II组、III组和IV组。I组（n = 20）-Endoseal（Prevest DenPro），II组（n = 20）-Apexit Plus（Ivoclar Vivadent），III组（n = 20）-MTA-FillApex（Angelus），IV组（n = 20）-Ceraseal（Meta Biomed）。将牙齿浸入印度墨水中7天，最后转移至水杨酸甲酯中进行透明化处理。使用体视显微镜测量染料渗透程度。采用方差分析（ANOVA）和Tukey检验进行统计数据分析。
所有组均观察到微渗漏。Endoseal组的根尖渗漏最大，其次是MTA Fillapex、Apexit和Ceraseal。通过单因素方差分析对各组进行比较，并使用Tukey的真实显著差异（HSD）检验测量平均差异的显著性。各组间染料渗透深度存在统计学显著差异（F = 28.66，P < 0.001）。
得出结论，实验组之间存在统计学显著差异。Ceraseal牙髓根管封闭剂提供了显著更好的根尖封闭效果，其次是Apexit和MTA Fillapex，而Endoseal的封闭能力最差。
