A total of 169 dentate persons, aged 76, 81, and 86 years, living at home in Helsinki, Finland, were examined by means of panoramic radiography supplemented by intraoral radiographs. The older the age group, the fewer teeth remained. Altogether 75% of the subjects had radiographically detectable caries. A high proportion of the carious teeth (62%) was found in a relatively small number (24%) of subjects. The number of carious teeth and their percentage of the total number of teeth were greater in the older age groups. The proportion of endodontically treated teeth was 19% in the 76-year-olds and 26% in the 86-year-olds. Of the subjects 41% had periapical periodontitis, which was commoner in root-filled teeth (18%) than in other teeth (4%). Caries and periapical radiolucent and radiopaque findings were commoner in men. Vertical bone pockets (3 mm or deeper) were found in 51% and furcation lesions in 28% of the subjects. Compared with earlier Finnish studies, the results indicate an improving oral health status among elderly Finns.
共有169名年龄分别为76岁、81岁和86岁的有牙老人，居住在芬兰赫尔辛基的家中，通过全景X线摄影并辅以口内X线片进行检查。年龄组越大，留存的牙齿越少。共有75%的受试者有X线片可检测到的龋齿。相当大比例（62%）的龋齿见于相对少数（24%）的受试者。年龄较大的年龄组中龋齿数量及其占牙齿总数的百分比更高。76岁组中接受牙髓治疗的牙齿比例为19%，86岁组中为26%。41%的受试者有根尖周炎，在根管充填的牙齿中（18%）比在其他牙齿中（4%）更常见。龋齿以及根尖周透射和阻射表现在男性中更常见。51%的受试者发现有垂直骨袋（3毫米或更深），28%的受试者有根分叉病变。与芬兰早期的研究相比，结果表明芬兰老年人的口腔健康状况有所改善。
