[The dynamics of parodontal disease incidence in young subjects in Cracow in 1969-1988].

The reported study was carried out on 1241 subjects aged from 5 to 25 years with symptoms of parodontal diseases who came to an outpatient clinic in the years 1969-1988. Gingivitis prevailed among the diagnoses--825 cases, while deep parodontal changes were found in 416 cases. The incidence of all parodontal diseases was higher in females, with the exception of ulcerative gingivitis which was more frequent in males. The patients from the City of Cracow prevailed over those from the provinces of Southern Poland, and the incidence of various disease entities varied in various years.
