目标.确定日本成年人群根尖周射线可透性和根管治疗的患病率。研究设计。采用全口口X线片对冈山大学附属牙科医院的672名成年患者的根尖周状态和根充长度进行了评价。总体而言，87%的受试者有牙根填充牙，70%的受试者表现出根尖射线可透性。在检查的16，232颗牙齿中，21%已经进行了根充，其中40%表现出根尖射线可透性。根充过充的牙齿或下颌切牙的根尖透亮线患病率最高。在日本人群中，牙根填充牙齿的患病率似乎高于欧洲或美国;然而，根尖射线可透牙齿与牙根填充牙齿的比例在其他国家报告的范围内。过度填充的牙齿和下颌切牙最有可能表现出根尖透亮线。
Objectives. To determine the prevalence of periapical radiolucencies and endodontic treatment in an adult Japanese population.Study design. Periapical status and length of root fillings of 672 adult patients attending Okayama University Hospital of Dentistry were evaluated using full mouth intraoral radiographs.Results. Overall, 87% of the subjects had root-filled teeth, and 70% exhibited in apical radiolucency. Of the 16,232 teeth examined, 21% had been root-filled, and, of these, 40% exhibited an apical radiolucency. Root-filled teeth that were overfilled or that were mandibular incisors had the highest prevalence of apical radiolucencies.Conclusions. The prevalence of root-filled teeth appears higher in this Japanese population than in Europe or America; however, the ratio of teeth with an apical radiolucency to root-filled teeth was within the range of that reported for other countries. Overfilled teeth and mandibular incisors are most likely to exhibit apical radiolucencies.
