Epidemiology of periodontal diseases: Difference between revisions

Baelum 1997 reported on the incidence of tooth loss over 10 years among adult and elderly Chinese and looked at some [[predictive factor]]s. There were 440 subjects, 8 of which were [[edentulous]] at baseline and 31 who lost all remaining teeth during the study period. Of the 401 who remained dentate, the incidence of tooth loss ranged from 45% in the 20-29 year old group to 96% in the 60 years plus group. He found that the best baseline predictors of tooth loss of all remaining teeth was that at least one tooth had attachment loss greater or equal to 7mm. As in other studies, a major portion of the total number of teeth lost was accounted for by a small group of persons. In this study, [[dental caries]] was the dominant reason for tooth loss.
