To report the frequency and distribution of root-filled teeth as well as the prevalence of apical periodontitis in an adult population in Turkey.
Digital panoramic radiographs of 1000 patients who were examined at the Baskent University Faculty of Dentistry between December 2004 and May 2005 were evaluated. Patients ageing <15 years and those with less than nine remaining teeth were excluded. The coronal and periapical status of all the teeth with the exception of third molars was examined according to the criteria proposed by De Moor et al. (2000). Statistical analysis was performed with the Rao and Scott adjusted chi-square test for the comparison of clustered binary data. In all, 24 433 teeth were examined. A total of 346 teeth (1.4%) had radiographic signs of apical periodontitis, and 812 were root filled (3.3%). Of the 812 root-filled teeth, 148 (18.2%) had apical periodontitis. Of the 23,621 nonroot-filled teeth, 198 (0.8%) had apical periodontitis. The number of root-filled teeth in male subjects was significantly less than that in female subjects (P < 0.001), but the presence of apical periodontitis in male subjects was significantly higher than that in female subjects (P < 0.05).
报告土耳其成年人群中根管充填牙的频率和分布情况以及根尖周炎的患病率。
对2004年12月至2005年5月间在巴斯肯大学牙科学院接受检查的1000例患者的数字化全景X线片进行了评估。排除年龄小于15岁的患者以及剩余牙齿少于9颗的患者。除第三磨牙外，所有牙齿的冠部和根尖部状况均根据德穆尔等人（2000年）提出的标准进行检查。采用Rao和Scott校正卡方检验对聚类二元数据进行统计分析。总共检查了24433颗牙齿。共有346颗牙齿（1.4%）有根尖周炎的影像学表现，812颗牙齿进行了根管充填（3.3%）。在812颗根管充填牙中，148颗（18.2%）有根尖周炎。在23621颗未根管充填的牙齿中，198颗（0.8%）有根尖周炎。男性根管充填牙的数量显著少于女性（P<0.001），但男性根尖周炎的患病率显著高于女性（P<0.05）。
*根尖周炎的患病率以及伴有根尖周炎的根管充填牙的频率低于其他国家的类似人群。*根管充填牙的数量与其他流行病学研究中的结果相当。
