This cross-sectional study determined the prevalence of apical periodontitis in 1035 root canal-treated teeth from adult French patients and investigated the influence of the quality of canal fillings and coronal restorations on the periradicular status. Periapical radiographs were used for analyses, and teeth were classified as healthy or diseased according to the periapical index scoring system. Overall, the prevalence of apical periodontitis in root canal-treated teeth was 33%. Only 19% of the teeth had endodontic treatments rated as adequate. The success rate (number of healthy teeth) for cases with adequate endodontic treatment was 91%, which was significantly higher when compared with teeth with inadequate treatment (61%). Teeth with adequate restorations had significantly decreased prevalence of apical periodontitis (29%) as compared with teeth with inadequate restorations (41%). The combination of adequate endodontic treatment and adequate restorations yielded the highest success rate (93.5%). The quality of the endodontic treatment was the most important factor for success, although the quality of the coronal restoration also influenced the treatment outcome.
这项横断面研究确定了1035颗来自成年法国患者的根管治疗牙齿中根尖周炎的患病率，并调查了根管充填质量和冠部修复对根尖周状况的影响。使用根尖片进行分析，并根据根尖指数评分系统将牙齿分为健康或患病。总体而言，根管治疗牙齿中根尖周炎的患病率为33%。只有19%的牙齿根管治疗被评为充分。根管治疗充分的病例成功率（健康牙齿数量）为91%，与治疗不充分的牙齿相比（61%）显著更高。修复充分的牙齿根尖周炎患病率（29%）与修复不充分的牙齿相比（41%）显著降低。根管治疗充分和修复充分相结合产生了最高的成功率（93.5%）。根管治疗质量是成功的最重要因素，尽管冠部修复质量也影响治疗结果。
