BACKGROUND
The aim of this study was to quantitatively analyze the amount of dye leakage with AH26, Sealapex and Tubliseal sealers in endodonticaly treated teeth.
MATERIALS AND METHODS
A total of 36 extracted mandibular molar specimens were divided into three groups; Group I: Sealapex, Group II: Tubliseal, Group II: AH26 with 12 samples in each group. Standard access cavity and biomechanical preparation was done with step back flare technique. Obturations were done using respective sealers in the three different groups. Then, samples were subjected to spectro photometric analysis using a filter of 670 nm. Spectrophotometric analysis was performed to quantitatively analyze the amount of dye leakage with all three sealers.
RESULTS
Tubliseal exhibited the least microleakage. In comparison to Sealapex, Tubliseal showed a significant difference. Compared to Sealapex, AH26 showed no significant difference. Comparisons made between Tubliseal and AH26 showed no significant difference.
CONCLUSION
In the present study, Tubliseal sealer showed least microleage compared with Sealapex and AH26 sealer.
背景
本研究的目的是定量分析AH26、Sealapex和Tubliseal封闭剂在根管治疗牙齿中的染料渗漏量。
材料与方法
总共36颗拔除的下颌磨牙标本被分为三组；第一组：Sealapex，第二组：Tubliseal，第三组：AH26，每组12个样本。采用逐步后退扩管技术进行标准开髓洞形和生物力学预备。在三个不同组中使用各自的封闭剂进行充填。然后，使用670nm的滤光片对样本进行分光光度分析。进行分光光度分析以定量分析所有三种封闭剂的染料渗漏量。
结果
Tubliseal表现出最少的微渗漏。与Sealapex相比，Tubliseal有显著差异。与Sealapex相比，AH26无显著差异。Tubliseal和AH26之间的比较无显著差异。
结论
在本研究中，与Sealapex和AH26封闭剂相比，Tubliseal封闭剂表现出最少的微渗漏。
