To determine the prevalence of periapical radiolucencies and endodontic treatment in an adult Japanese population.
Periapical status and length of root fillings of 672 adult patients attending Okayama University Hospital of Dentistry were evaluated using full mouth intraoral radiographs.
Overall, 87% of the subjects had root-filled teeth, and 70% exhibited an 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.
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.
确定日本成年人群中根尖周透射影和根管治疗的患病率。
使用全口口腔内X光片对672名就诊于冈山大学牙科学院医院的成年患者的根尖周状况和根管充填长度进行评估。
总体而言，87%的受试者有根管充填牙，70%有根尖透射影。在检查的16232颗牙齿中，21%已进行根管充填，其中40%有根尖透射影。根管充填超充的牙齿或下颌切牙的根尖透射影患病率最高。
在该日本人群中，根管充填牙的患病率似乎高于欧洲或美国；然而，根尖有透射影的牙齿与根管充填牙的比例在其他国家报告的范围内。超充的牙齿和下颌切牙最有可能出现根尖透射影。
