The objective of this study was to determine possible independent risk indicators of apical periodontitis (AP) in root-filled teeth in an adult Turkish population.
This study included subjects older than 15 years who had 1 or more root-filled teeth examined at the Baskent University Faculty of Dentistry. A total of 812 root-filled teeth were evaluated in 425 individuals. AP was the dependent variable and age, gender, length and density of root fillings, presence of periodontal problems, posts, localization of tooth, and tooth type were identified as independent variables. Generalized Estimating Equation (GEE) models were used in statistical analysis.
AP was detected on 148 teeth (18.2%) in 812 root-filled teeth. According to multiple GEE model, males were more likely to have AP than females. Of the dental variables, length of root fillings, periodontal problems and tooth type were significantly associated with AP.
The present study indicates that to be male and dental variables including length of root fillings, periodontal problems, and molar teeth were significantly associated with AP.
本研究的目的是确定成年土耳其人群中根管充填牙发生根尖周炎（AP）的可能独立风险指标。
本研究纳入了15岁以上、在巴斯肯特大学牙科学院接受过1颗或更多颗根管充填牙检查的受试者。对425名个体的总共812颗根管充填牙进行了评估。AP为因变量，年龄、性别、根管充填物的长度和密度、牙周问题的存在、桩、牙齿位置及牙齿类型被确定为自变量。统计分析采用广义估计方程（GEE）模型。
在812颗根管充填牙中，148颗牙（18.2%）检测到AP。根据多重GEE模型，男性比女性更易发生AP。在牙齿变量中，根管充填物长度、牙周问题和牙齿类型与AP显著相关。
本研究表明，男性以及包括根管充填物长度、牙周问题和磨牙在内的牙齿变量与AP显著相关。
