The present study was conducted with the aim to assess the extraction and retention incidence of endodontically treated teeth with an uncertain prognosis after endodontic referral and to evaluate the factors related to the decision-making process.
Two hundred seventy-five permanent teeth were clinically and radiographically evaluated by 3 experienced endodontists. The type of tooth, age and sex of the patients, the motive of referral, and the main chief complaint were the initial recorded data. The associations between extraction reasons and the patients' age and sex or tooth type were analyzed using the chi-square test.
Of the 275 teeth examined, 217 (79%) were finally extracted. The remaining 58 (21%) teeth were endodontically retreated and restored. A questionable clinical status was the main motive for endodontic referral (57.1%). The teeth most extracted were maxillary molars (36.2%) followed by mandibular molars (32.9%). The most prevalent reason for extraction was nonrestorable caries (37.1%). The majority of the teeth retained in the oral cavity needed surgical periodontal or endodontic management.
The most frequent reason responsible for the fate of endodontically treated teeth is the pronounced loss of dental tissues. Endodontic referral may aid in the survival of some carefully selected cases of endodontically treated teeth.
本研究旨在评估经根管治疗后预后不确定的患牙在根管治疗转诊后的拔除和保留率，并评估与决策过程相关的因素。
3 名经验丰富的牙髓病医生对 275 颗恒牙进行了临床和影像学评估。记录的初始数据包括牙齿类型、患者年龄和性别、转诊原因以及主要主诉。使用卡方检验分析拔牙原因与患者年龄和性别或牙齿类型之间的关系。
在检查的 275 颗牙齿中，217 颗（79%）最终被拔除。其余 58 颗（21%）牙齿经根管再治疗和修复后得以保留。有疑问的临床状况是根管治疗转诊的主要原因（57.1%）。最常被拔除的牙齿是上颌磨牙（36.2%），其次是下颌磨牙（32.9%）。拔牙的最常见原因是非可修复性龋坏（37.1%）。保留在口腔中的大部分牙齿需要进行牙周或牙髓手术治疗。
导致根管治疗后牙齿命运的最常见原因是明显的牙体组织丧失。根管治疗转诊可能有助于一些经过精心挑选的根管治疗后患牙的存活。
