摘　　要：目的：从X线影像学角度评估牙体牙髓科专科医师完成的成年人根管治疗的充填质量。方法：随机抽取2012~2013年东莞健力口腔医院牙体牙髓科的1600份病历,共计1050个病人的1391个进行根管治疗患牙的2306个根管纳入评估,每一根管充填的牙齿至少检查3张根尖X线片：术前片、试尖片和术后片。评估的指标为根管充填的长度、致密度和锥度。根管充填的长度依据根充物与影像学根尖的关系记录为恰充、欠充或超充。根管充填的致密度和锥度依据有无空隙和充填物的连续锥度记录为足够或欠缺。用卡方检验统计分析不同牙位、上下颌及不同弯曲度根管的充填质量。结果：根充长度、致密度和锥度的合格率分别为87.6%、69.8%和95.8%,只有57.8%的根管充填3项指标同时合格。根充的长度、致密度和锥度与根管弯曲度的关系有统计学显著性（P〈0.001）。上颌牙根充合格率高于下颌牙（P〈0.001）;前牙的根充合格率高于后牙（P〈0.001）;直根管的根充合格率高于弯曲根管（P〈0.001）;上颌尖牙的根充合格率最高（78.8%）。结论：牙体牙髓科专科医师完成的成年人根管治疗根充质量合格率高于50%。Objective：To evaluate radiographically the technical quality of root canal treatment performed by endodontists among an adult population attending the dental clinic in Dongguan,China between 2012 and 2013.Methods：A random sample of 1600 records of patients who received dental treatment at Jianli Stomatological Hospital of Dongguan between2012 and 2013was examined.A total of 1391 endodontically treated teeth with 2306 root canals in 1050 dental patients were evaluated.For each root-filled tooth,at least three periapical radiographs were examined：preoperative,working length determination and postoperative.The length,density and taper of root fillings were recorded.The length of root fillings was recorded as adequate,short or overfilled based on their relationship with the radiographic apex.Density and taper of fillings were recorded as adequate or inadequate based on the presence of voids and the uniform tapering of the fillings,respectively.Chi-square analysis was used to determine the adequacy of root canal filling in teeth with different location,position or curvature.Results：Eighty-seven percent,69.8%and 75.8% of the root fillings had adequate length,density or taper,respectively.And only 57.8% of the root fillings fulfilled these criteria at the same time.The relationship between the length,density or taper of the root fillings and the canal curvature was statistically significant（P〈0.001）.Adequate fillings were found more in maxillary teeth than in mandibular teeth（P〈0.001）,in anterior teeth compared to posterior teeth（P〈0.001）,and in straight canals compared to curved canals（P〈0.001）.The highest percentage of adequate root fillings was found in maxillary incisors（78.8%）.Conclusion：The acceptability of root fillings among an adult Chinese population performed by endodontists was found to be more than 50%.
