Pulpitis results in significant morbidity among the elderly, particularly in underserved communities. We collected panoramic oral radiographs from 244 (mean age 67) participants of the Northern Manhattan Study, a prospective cohort study of stroke risk in a multiethnic urban population. Radiographs were evaluated for missing teeth, caries, restorations, periodontal bone loss, adequacy of endodontic treatment, and periapical radiolucencies. In the study 206 subjects were dentate (mean 17.1 teeth). 5.1% of teeth had periapical radiolucencies, and 4.8% had been endodontically treated; 37.5% of endodontically treated teeth had periapical radiolucencies. Teeth with restorations, periodontal bone loss, pulpotomy, and inadequate root canal filling had a significantly higher occurrence of periapical radiolucency (p < 0.05). Among all root filled teeth, only 26% were deemed satisfactory. We conclude that apical periodontitis is widely prevalent and the technical standard of root fillings is poor in this cohort. There is a substantial need for improved dental care among the northern Manhattan elderly.
牙髓炎在老年人中导致了显著的发病率，尤其是在医疗服务不足的社区。我们从北曼哈顿研究的244名参与者（平均年龄67岁）中收集了全景口腔X光片，该研究是一项针对多民族城市人群中风风险的前瞻性队列研究。对X光片进行了牙齿缺失、龋齿、修复体、牙周骨丧失、牙髓治疗的充分性以及根尖周透射影的评估。在该研究中，206名受试者有牙（平均17.1颗牙）。5.1%的牙齿有根尖周透射影，4.8%的牙齿接受了牙髓治疗；接受牙髓治疗的牙齿中有37.5%有根尖周透射影。有修复体、牙周骨丧失、牙髓切断术和根管充填不足的牙齿根尖周透射影的发生率显著更高（p < 0.05）。在所有根管充填的牙齿中，只有26%被认为是满意的。我们得出结论，根尖周炎在该队列中广泛流行，根管充填的技术标准较差。曼哈顿北部的老年人非常需要改善牙科护理。
