title: [Preliminary research on radiographic manifestations of health odontal and periodontal tissues in elderly people].
abstract: Radiographs of mandibular first molars in 45 patients aged more than 60 year old were measured on several parameters of pulpal chamber, root canal as well as alveolar crest, and compared with those in 40 young people in order to study the radiographic manifestations of the healthy odontal and periodontal tissues in elderly people. Results shown that in aged people the average width and height of the pulpal chamber and the diameter of root canal were narrower; the root canal walls were thicker; the relation between the height of alveolar crest and the root length reduced significantly; and the lamina dura on the alveolar crest disappeared more common. Findings lay a preliminary foundation for investigation on radiographic manifestations of involved teeth in gerontology.
