The first permanent molar (FPM) is considered the tooth most susceptible to caries, as it is the first permanent tooth to erupt in the oral cavity, making it susceptible to environmental conditions that may appear as caries, hypoplasia, or hypomineralization Several treatment options are available for managing deep caries, including root canal treatment (RCT). However, there is a lack of data on the success and failure rates of RCT in FPM among children. This study aimed to determine the success and failure rates of RCT in FPM among children and related factors.
This retrospective cohort study was conducted at three major centers in Jeddah, Saudi Arabia. Children aged 9-18 years who underwent an RCT between 2010 and 2019 were included. Clinical and radiographic examinations were also performed.
Based on the loose criteria, most of the evaluated teeth (79.6%) were successfully treated. The treatment failed in only 20.4% of participants. Older patients and teeth with acceptable restoration quality had an increased success rate compared to younger patients and teeth with unacceptable restoration quality. A shorter time lapse between treatment and assessment resulted in a lower success rate compared to a longer time lapse. Based on strict criteria, 72.9% of the patients were successfully treated. The use of a microscope and teeth with acceptable restoration quality resulted in an increased success rate compared to teeth treated without the microscope and with unacceptable restoration quality.
The success rate of this procedure was high. Several factors, including older age, acceptable restoration quality, and the use of a microscope, increase the probability of success.
第一恒磨牙（FPM）被认为是最易患龋齿的牙齿，因为它是口腔中最早萌出的恒牙，使其易受可能表现为龋齿、发育不全或矿化不足的环境因素影响。对于治疗深龋有多种治疗选择，包括根管治疗（RCT）。然而，关于儿童FPM根管治疗成功率和失败率的数据匮乏。本研究旨在确定儿童FPM根管治疗的成功率和失败率以及相关因素。
这项回顾性队列研究在沙特阿拉伯吉达的三个主要中心进行。纳入了2010年至2019年间接受根管治疗的9至18岁儿童。还进行了临床和影像学检查。
基于宽松标准，大多数评估牙齿（79.6%）治疗成功。仅20.4%的参与者治疗失败。与年轻患者和修复质量不可接受的牙齿相比，年龄较大的患者和修复质量可接受的牙齿成功率更高。与较长时间间隔相比，治疗与评估之间的时间间隔较短导致成功率较低。基于严格标准，72.9%的患者治疗成功。与未使用显微镜且修复质量不可接受的牙齿相比，使用显微镜和修复质量可接受的牙齿成功率更高。
该治疗方法的成功率较高。包括年龄较大、修复质量可接受以及使用显微镜在内的几个因素会增加成功的概率。
