【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(P0.001)。上颌牙根充合格率高于下颌牙(P0.001);前牙的根充合格率高于后牙(P0.001);直根管的根充合格率高于弯曲根管(P0.001);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%。
[Abstract]:Objective: to evaluate the filling quality of adult root canal therapy performed by dental pulp specialist. Methods: 1600 medical records of dental pulp department of Dongguan Jianli Stomatology Hospital were randomly selected from 2012 to 2013. 1391 of 1050 patients were included in the assessment of 2306 teeth treated by root canal therapy. At least 3 apical radiographs were examined for each canal-filled tooth: pre-, post-operative and apical films. The length, density and taper of root canal filling were evaluated. The length of root canal filling was recorded as full, underfilled or supercharged according to the relationship between root filling and imaging root tip. The density and taper of root canal filling are sufficient or deficient based on the continuous taper records of the filling and the void. Chi-square test was used to analyze the filling quality of root canal in different tooth position, upper and lower jaw and different curvature. Results: the qualified rates of root filling length, density and taper were 87.6% and 95.8% respectively, and only 57.8% of root canal filling were qualified simultaneously. The relationship between root filling length, density and taper and root canal curvature was statistically significant (P 0.001). The qualified rate of root filling of maxillary teeth was higher than that of mandibular teeth (P 0.001), that of anterior teeth was higher than that of posterior teeth (P 0.001), that of straight root canals was higher than that of curved canals (P 0.001), and that of maxillary canine teeth was higher than that of maxillary canines (78.8%). Conclusion: the qualified rate of adult root canal therapy is higher than 50%.
