摘要
目的探讨上颌第二前磨牙多根多根管的发现及根管治疗方法,以期为根管治疗提供参考。方法对1例上颌第二前磨牙咬合不适伴冷热刺激痛及自发性痛的患者的病例资料和相关文献进行回顾分析。结果本病例通过CBCT明确了患牙的牙根及根管数目为3根4根管,在口腔手术显微镜的辅助下使用机用镍钛器械和热塑牙胶进行了完善的根管治疗,术后患者临床症状消失。结论上颌第二前磨牙根管系统复杂,借助CBCT和口腔手术显微镜可发现和定位根管,并完成高质量的根管治疗。
Objective To explore the discovery and treatment of multiple root canals in the maxillary second premolar to provide a reference for root canal therapy.Methods A case of maxillary second premolar occlusal discomfort accompanied by cold and heat stimulation pain and spontaneous pain was analyzed retrospectively.Results In this case,the number of roots and root canals in the tooth was determined by CBCT to be three roots with four canals.Root canal therapy was performed with Ni-Ti endodontic files and thermoplastic gutta-percha via root optical microscopy.The clinical symptoms disappeared after the operation.Conclusion The maxillary second premolar root canal system is complex,and additional root canals can be found and located with CBCT and optical microscopy.High-quality root canal therapy was completed.
