[Comparative study of the prevalence of disorders of impaired structure of dental tissues in school children and university students].

Abstract

The authors examined a group of 573 Prague children aged 12-15 years. In addition to the incidence of disorders of the structure of dental tissues they investigated the coriosity (DPE), oral hygiene (OHI) and condition of the gingiva (PI). Their main interest was focused on impaired mineralization of dental tissues the incidence of which is indemic in Prague children. The group was compared with 62 university students. It is of interest that in all indicator except impaired mineralization, the children had significantly better results. The rising curve of impaired mineralization signalises the ever deteriorating living environment in the capital.
