Abstract

This study evaluated the retreatability of two bioceramic-based sealers in oval-shaped canals and the effectiveness of supplementary cleaning techniques for removing sealer remnants. Mandibular premolars were obturated with either NeoSEALER Flo or AH Plus Bioceramic. After obturation, specimens were retreated followed by supplementary cleaning with XP-Endo Finisher R, EasyClean, or passive ultrasonic irrigation. Sealer remnants were analysed using confocal laser scanning microscopy and scanning electron microscopy. AH Plus Bioceramic showed a significantly lower residual sealer percentage than NeoSEALER Flo in the coronal and middle thirds. XP-Endo Finisher R was more effective for NeoSEALER Flo in the apical third, while passive ultrasonic irrigation was superior for AH Plus Bioceramic in the coronal and middle thirds. Scanning electron microscopy revealed sealer remnants in all groups, with partial obstruction of dentinal tubules. Bioceramic sealers exhibit different retreatability, and supplementary cleaning protocols improved sealer removal, but none achieved complete canal wall cleanliness.

生物陶瓷封闭物在椭圆管中去除的可退性及不同辅助清洁技术的评价。

本研究评估了两种基于生物陶瓷的封闭剂在椭圆形管中的可退性，以及辅助清洁技术去除封闭剂残留物的有效性。下颌前磨牙用NeoSEALER floo或AH Plus生物陶瓷进行封闭。封闭后，退回标本，然后用XP-Endo Finisher R、EasyClean或被动超声冲洗进行补充清洁。采用激光共聚焦扫描显微镜和扫描电镜对封口剂残留物进行分析。AH Plus Bioceramic在冠状和中间三分之一处的残留封闭百分比明显低于NeoSEALER Flo。XP-Endo Finisher R对NeoSEALER Flo的根尖三分之一更有效，而被动超声冲洗对AH Plus Bioceramic的冠状和中三分之一更有效。扫描电镜显示，所有组均有牙本质小管部分阻塞。生物陶瓷密封剂表现出不同的可退性，补充清洁方案改善了密封剂的去除，但没有一种能达到完全的管壁清洁度。

期刊介绍： The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
