Biomechanical preparation of root canals with accentuated curvature is challenging. New rotatory systems, such as Reciproc, require a shorter period of time to prepare curved canals, and became a viable alternative for endodontic treatment of teeth with root dilaceration. Thus, this study aimed to report a clinical case of endodontic therapy of root with accentuated dilaceration using Reciproc single-file system. Mandibular right second molar was diagnosed as asymptomatic irreversible pulpitis. Pulp chamber access was performed, and glide path was created with #10 K-file (Dentsply Maillefer) and PathFile #13, #16 and #19 (Dentsply Maillefer) up to the temporary working length. The working length measured corresponded to 20 mm in the mesio-buccal and mesio-lingual canals, and 22 mm in the distal canal. The R25 file (VDW GmbH) was used in all the canals for instrumentation and final preparation, followed by filling with Reciproc gutta-percha cones (VDW GmbH) and AH Plus sealer (Dentsply Maillefer), using thermal compaction technique. The case has been receiving follow-up for 6 mon and no painful symptomatology or periapical lesions have been found. Despite the difficulties, the treatment could be performed in a shorter period of time than the conventional methods.
对有明显弯曲的根管进行生物力学预备具有挑战性。新型旋转系统，如Reciproc，预备弯曲根管所需时间更短，成为牙根折裂牙齿牙髓治疗的一种可行替代方法。因此，本研究旨在报告一例使用Reciproc单根管系统对有明显折裂的牙根进行牙髓治疗的临床病例。右下第二磨牙被诊断为无症状性不可逆性牙髓炎。进行了髓腔入路，并用#10 K锉（登士柏迈弗公司）和PathFile #13、#16和#19（登士柏迈弗公司）建立至临时工作长度的引导通路。测量的工作长度在近中颊根管和近中舌根管为20 mm，在远中根管为22 mm。所有根管均使用R25锉（VDW有限公司）进行器械预备和最终预备，随后采用热压技术，用Reciproc牙胶尖（VDW有限公司）和AH Plus封闭剂（登士柏迈弗公司）进行充填。该病例已随访6个月，未发现疼痛症状或根尖周病变。尽管存在困难，但与传统方法相比，该治疗可在更短时间内完成。
