The results of the reported study showed considerable differences in the causes of attending dental health service offices, and differences in the health state of the stomatognathic system in the studied populations in certain provinces. Not always these differences were due to the index of dental health service availability. The index of this availability had a significant effect on the results of the therapeutic activity of dentists, and was unrelated to the results of prophylactic activities. Usually more teeth with active caries and more missing teeth were in the provinces with prevalence of peasant population. At the same time these provinces had a lower per cent of subjects with unfilled gaps in teeth. High per cent of studied subjects with missing teeth, usually not replaced or only partially reconstructed can be explained by very low attendance of patients to prosthetic laboratories.
