Since abnormal tooth morphology can predispose to caries and periodontal disease, careful management of fused teeth is essential. In this paper we report a rare case of a fused molar and supernumerary tooth and describe its management. Caries was removed from the tooth complex under local anesthesia. The pulp chamber of the supernumerary tooth was exposed without involvement of second molar pulp chamber. The root canal of the supernumerary tooth was prepared using the step back technique and copious irrigation with 2.6% sodium hypochlorite. Obturation using the lateral condensation technique with gutta-percha and AH26 sealer was subsequently performed and final restoration was accomplished with composite resin. Nine months after the treatment, no clinical or radiographic concern is apparent, and the second molar tooth has remained vital.
由于异常的牙齿形态可能易患龋齿和牙周疾病，因此对融合牙进行仔细处理至关重要。在本文中，我们报告了一例罕见的融合磨牙与多生牙病例，并描述了其处理过程。在局部麻醉下从牙齿复合体中去除龋齿。多生牙的髓腔暴露，未累及第二磨牙的髓腔。采用逐步后退技术预备多生牙的根管，并用2.6%的次氯酸钠大量冲洗。随后使用牙胶尖和AH26封闭剂通过侧向加压技术进行根管充填，并用复合树脂完成最终修复。治疗九个月后，未发现明显的临床或影像学问题，第二磨牙仍保持活力。
