The present study aimed at investigating the prevalence of Apical periodontitis in a Moroccan Adult subpopulation with a non-surgical root canal treatment and to assess associated risk factors including endodontic treatment quality, periodontal health status, coronal restoration cavity design and quality.
A total of 358 endodontically treated teeth were evaluated after more than 1-year period in a Moroccan subpopulation according to predetermined criteria. Studied parameters were assessed clinically and radiographically. The association between coronal restoration quality, cavity design, periodontal status, root canal filling quality, coronal restoration related features, presence or absence of the opposing dentition and the periapical status was determined. Data were analyzed using chi-square test, odds ratio and logistic regression.
The present study revealed that gingival health, coronal restoration with CL II cavity design, and root canal filling quality influenced periapical status of endodontically treated teeth. Multivariate analysis showed that this association was statistically significant for gingival inflammation (95% CI 1.08-3.91, OR 2.05, p = 0.02), inadequate coronal restoration (95% CI 1.16-4.04, OR 2.16, p = 0.01), inadequate root canal filling length and homogeneity (95% CI 1.24-3.01, OR 1.93, P = 0.004), (95% CI 1.41-4.44, OR 2.50, p = 0.002) respectively.
The present study revealed that inadequate coronal restorations especially with large proximal margins (CL II cavity design) and gingival inflammation increased the risk of apical periodontitis in endodontically treated teeth. Prevalence of Apical periodontitis in the present study was 72.1%.
本研究旨在调查摩洛哥成年人接受非手术根管治疗后的根尖周病患病率，并评估相关风险因素，包括根管治疗质量、牙周健康状况、冠部修复体的窝洞设计和质量。
根据预定标准，对摩洛哥人群中超过 1 年的 358 颗根管治疗牙进行评估。临床和放射学评估研究参数。确定冠部修复体质量、窝洞设计、牙周状况、根管充填质量、冠部修复体相关特征、对颌牙的存在与否与根尖周状况之间的关系。使用卡方检验、比值比和逻辑回归分析数据。
本研究表明，牙龈健康、CL II 窝洞设计的冠部修复体和根管充填质量影响根管治疗牙的根尖周状况。多变量分析显示，牙龈炎症（95%CI 1.08-3.91，OR 2.05，p=0.02）、冠部修复不充分（95%CI 1.16-4.04，OR 2.16，p=0.01）、根管充填长度和均匀性不足（95%CI 1.24-3.01，OR 1.93，P=0.004）分别与根尖周病有统计学显著相关性。（95%CI 1.41-4.44，OR 2.50，p=0.002）。
本研究表明，不充分的冠部修复体，特别是具有较大近中边缘的（CL II 窝洞设计）和牙龈炎症，增加了根管治疗牙发生根尖周病的风险。本研究中根尖周病的患病率为 72.1%。
