Trauma to primary tooth leads to abnormal variations in crown and root canals of permanent teeth that presents a challenge in diagnosis and clinical management to the practitioner. This article presents a detailed case report of the endodontic treatment of a three canalled maxillary central incisor and maxillary lateral incisor having single canal with open apex linked with periodontal defect. Root canals were prepared with hand files and canals were irrigated with 2.5% sodium hypochlorite solution. Calcium hydroxide was placed as an intracanal medicament. As the expected healing did not occur even after one month of calcium hydroxide therapy, so periapical endodontic surgery was performed using Platelet Rich Plasma (PRP). Satisfactory clinical and radiographic results were obtained at 12 months. Detailed knowledge of the anatomical variations in the root canal and awareness of their configuration is essential for the success of such cases.
乳牙外伤会导致恒牙冠部和根管出现异常变化，这给从业者的诊断和临床管理带来了挑战。本文详细报告了一例上颌中切牙三根根管和上颌侧切牙单根管且根尖开放并伴有牙周缺损的牙髓治疗病例。使用手动锉预备根管，并用2.5%的次氯酸钠溶液冲洗根管。将氢氧化钙作为根管内药物放置。即使在氢氧化钙治疗一个月后仍未出现预期的愈合情况，因此使用富血小板血浆（PRP）进行了根尖牙髓手术。在12个月时获得了满意的临床和影像学结果。对于此类病例的成功，详细了解根管的解剖变异及其形态至关重要。
