Taurodontism is an anomaly affecting the morphology and anatomy of the tooth, leading to apical displacement of the furcation in multirooted teeth. This leads to an enlarged body of the tooth and reduced size of the root. Taurodontism is a rare dental finding. The endodontic management of such teeth is challenging because of their altered morphology, presence of extra canals, and enlarged pulp chamber. A cone-beam computed tomography is recommended to analyze the root canal morphology. Endocrowns can be used for prosthetic rehabilitation as they utilize retention from the elongated pulp chamber. This case presents a rare occurrence of bilateral maxillary and mandibular teeth with taurodontism. Five out of eight teeth were hypertaurodont, which is a very rare phenomenon. Two teeth were root canal treated followed by rehabilitation with endocrown.
牛牙样变是一种影响牙齿形态和解剖结构的异常情况，导致多根牙的根分叉向根尖移位。这会导致牙体增大而牙根变小。牛牙样变是一种罕见的牙齿表现。由于此类牙齿形态改变、存在额外根管以及髓腔扩大，其根管治疗具有挑战性。建议使用锥形束计算机断层扫描来分析根管形态。内冠可用于修复治疗，因为它们利用了伸长的髓腔进行固位。本病例呈现了罕见的双侧上颌和下颌牙齿牛牙样变情况。八颗牙齿中有五颗为巨牛牙样变，这是一种非常罕见的现象。两颗牙齿接受了根管治疗，随后用内冠进行修复。
