摘要
目的：牙出牙后牙根继续生长和根尖闭合。在此期间，如果牙髓因蛀牙或外伤而丧失活力，牙根生长可能会停止。在这些病例中，由于根管宽和缺乏根尖停止，成功的根管治疗是具有挑战性的。新型预混生物陶瓷根修复腻子提供优越的处理和愈合性能。本研究的目的是利用微ct分析来评估三种生物陶瓷腻子（BIO-C Repair、NeoMTA腻子和EndoSequence BC RRM Fast Set腻子）的填充能力和体积变化。方法：采用36颗刚拔除的单根直根管牙，根据材料的不同分为3组。模拟未成熟牙齿。分别对每个牙根进行封闭前后的显微ct成像。空隙以根管空间体积与修复材料体积之差的百分比计算。数据采用单因素方差分析（ANOVA）进行统计学分析，显著性水平设为α=0.05。结果：各组根端充填后均出现边缘间隙和/或内腔。3 mm处管体体积和材料体积组间差异无统计学意义（p < 0.05）。但空泡率差异有统计学意义（p=0.003）；Bio-C Repair（9.28+-3.27%）和EndoSequence BC RRM（6.7+-2.72%）显著高于两者，差异无统计学意义，而NeoMTA Putty（3.73+-1.69%）显著低于两者。结论：与EndoSequence BC RRM和BIO-C Repair相比，NeoMTA Putty在固化后表现出最小的体积变化。随着时间的推移，最小的尺寸变化有助于材料的耐用性和有效性，从而增强了长期稳定性，可能会带来更好的治疗效果，使NeoMTA Putty成为各种根管应用的可靠选择，可能会提高成功率和患者的治疗效果。(eej - 2024 - 07 - 114)。
Micro-CT Analysis of Apical Plug Using Various Premixed Bio-ceramic Putties: An In Vitro Study.
Objective: Root growth and apical closure continue after tooth eruption. Root growth may cease if pulp viability is lost due to caries or trauma during this period. Successful endodontic treatment is challenging in these cases due to wide root canals and lack of apical stops. New premixed bioceramic root repair putties offer superior handling and healing properties. The aim of this study is to evaluate the filling ability and volumetric changes of three bioceramic putties (BIO-C Repair, NeoMTA Putty, and EndoSequence BC RRM Fast Set Putty) using micro-CT analysis.
Methods: Thirty-six freshly extracted single-rooted teeth with straight root canals were used, divided into three groups based on the materials. Immature teeth were simulated. Pre- and post-obturated micro-CT images were taken for each root. Voids were calculated as the percentage difference between canal space volume and repair material volume. The data were then analysed statistically using one-way analysis of variance (ANOVA) with the level of significance set at α=0.05.
Results: All groups showed marginal gaps and/or internal voids after root-end filling. No significant difference between groups in canal and material volumes was detected at 3 mm (p>0.05). However, void percentage differences were significant (p=0.003); Bio-C Repair (9.28+-3.27%) and EndoSequence BC RRM (6.7+-2.72%) were significantly higher with no difference between them, while NeoMTA Putty (3.73+-1.69%) was significantly lower.
Conclusion: NeoMTA Putty exhibited the least volumetric alterations after setting, compared to EndoSequence BC RRM and BIO-C Repair. Enhanced long-term stability as a minimal dimensional change contributes to the material's durability and effectiveness over time, potentially leading to better treatment outcomes making NeoMTA Putty a reliable choice for various endodontic applications, potentially leading to improved success rates and patient outcomes.
