[Comparison of oral health in metropolitan and nonmetropolitan district of Leipzig in 1979 and 1989 (ICS I replication study)].

Abstract

In 1989 the Leipzig-ICS-I study from 1979 was replated according to the same methodology on randomized probands (N = 2693). A significant reduction of the dmft-value (27%) and DMF-value (50 resp. 27%) with clear increased f(F)-value was found at 8/9 and 13/14, years olds. At the same time there was a caries increment of 1.9 DMFT from 1979 to 16 DMFT in 1989 in the age group of 35-44 years. Again in this group was found a very low edentulousness (0.3%) and a very high number of natural teeth (25.9). During 10 years the prevalence of dentofacial anomalies decreased about 25.6% (13 to 14 years old) and in the adult group the prostetic treatment needs decreased by half. The results reveal an essential improved oral health status in consequence of intensive dental care. Unsatisfied is the periodontal status. 90% of subjects need oral hygiene measures.
