Pushout bond strength evaluation determines the efficiency of sealer which provides better adaptation, sealing ability, and complete fluid-tight hermetic seal, thereby preventing the entry of microorganisms and reinfection.
The study aimed to evaluate the pushout bond strength of the teeth obturated with bioceramic gutta-percha coated with AH Plus, CeraSeal, and BioRoot RCS sealer.
This was an study.
Sixty human mandibular premolar teeth with single roots were decoronated to provide 15 mm length. Instrumentation was done using the Micro Mega Hero Shaper Gold Rotary Files till F3. Canals were irrigated with 5.25% NaOCl, 17% ethylenediaminetetraacetic acid solution, and saline and dried. Samples were divided into three groups: Group I ( = 20) obturated with bioceramic gutta-percha coated with AH Plus, Group II ( = 20) obturated with bioceramic gutta-percha coated with CeraSeal, Group III ( = 20) obturated with bioceramic gutta-percha coated with BioRoot RCS. Finally, the samples were coronally sealed with a temporary filling material and stored in 100% humidity at 37ºC for 14 days. Then, pushout bond strength evaluation of all samples was done using a Universal Testing Machine.
Data were analyzed by one-way ANOVA, followed by Bonferroni analysis, for the multiple intergroup comparisons.
Analysis using ANOVA showed a statistically significant difference ( < 0.05) in coronal, middle, and apical third sections of all groups. Analysis done using Bonferroni showed a statistically significant difference ( < 0.05) in all sections when compared with Group III (BioRoot RCS).
BioRoot RCS sealer showed better pushout bond strength values when compared to CeraSeal sealer and AH Plus sealer.
推出粘结强度评估可确定封闭剂的效率，该封闭剂能提供更好的适应性、密封能力以及完全的液密性气密密封，从而防止微生物进入和再次感染。
本研究旨在评估用涂有AH Plus、CeraSeal和BioRoot RCS封闭剂的生物陶瓷牙胶尖充填的牙齿的推出粘结强度。
这是一项[此处原文缺失相关信息]研究。
选取60颗单根的人类下颌前磨牙，截冠后保留15毫米长度。使用Micro Mega Hero Shaper Gold旋转锉进行根管预备至F3。根管先用5.25%次氯酸钠、17%乙二胺四乙酸溶液冲洗，再用生理盐水冲洗并干燥。样本分为三组：第一组（n = 20）用涂有AH Plus的生物陶瓷牙胶尖充填，第二组（n = 20）用涂有CeraSeal的生物陶瓷牙胶尖充填，第三组（n = 20）用涂有BioRoot RCS的生物陶瓷牙胶尖充填。最后，用临时充填材料对样本进行冠部密封，并在37℃、100%湿度条件下储存14天。然后，使用万能试验机对所有样本进行推出粘结强度评估。
数据采用单因素方差分析，随后进行Bonferroni分析，用于多组间比较。
方差分析显示，所有组在冠部、中部和根尖三分之一处存在统计学显著差异（P < 0.05）。与第三组（BioRoot RCS）相比，Bonferroni分析显示所有部位均存在统计学显著差异（P < 0.05）。
与CeraSeal封闭剂和AH Plus封闭剂相比，BioRoot RCS封闭剂显示出更好的推出粘结强度值。
