Abstract:
Gemination is a rare phenomenon in the maxillary posterior teeth. Endodontic treatment of these teeth requires special care due to the bizarre anatomy particularly when it is accompanied by a C-shaped canal system. This report illustrates a patient with a rare geminated C-shaped maxillary second molar comprised of two sections in its crown, including a geminated section attached to a normal coronal of a second maxillary molar diagnosed with the pulpal status \"necrosis\" and \"irreversible pulpitis\" in geminated section and the molar respectively. Thus, endodontic treatment was performed on both parts of the tooth. Two months follow-up revealed well-functioning teeth with normal status of periapical tissue with no mobility or abnormality. Successful treatment of unusual anatomical teeth requires adherence to biomechanical principles of canal preparation and coronal restoration.
摘要:
在上颌后牙中,发育是一种罕见的现象。这些牙齿的牙髓治疗需要特别的护理,由于奇怪的解剖结构,特别是当它伴随着C形管系统时。该报告说明了一名罕见的C形上颌第二磨牙的患者,其牙冠上有两个部分,包括附于第二颗上颌磨牙的正常冠状部分,分别在成牙部分和磨牙中诊断为牙髓状态“坏死”和“不可逆牙髓炎”。因此,对牙齿的两部分进行了牙髓治疗.两个月的随访显示牙齿功能良好,根尖周组织状态正常,无活动性或异常。成功治疗不寻常的解剖牙齿需要遵守管准备和冠状修复的生物力学原则。
