[The condition of teeth in adult population aged 35-44 years living in a small town and in villages in the Province of Poznan].

In an epidemiological study the condition of teeth was assessed in 120 subjects aged 35-44 years living in Sroda Wielkopolska and villages around it. Group I (60 subjects) lived in the town and group II (60 subjects) came from villages. Each group contained 30 women and 30 men. A high prevalence of caries was found, (99.16% for the whole studied population) with the mean DMF value 16.79%. The highest DMF values were found in group II in women--21.66. These high values of DMF were due to a great number of carietic teeth, teeth removed because of caries, and a relatively small number of teeth with fillings. Slight developmental disturbances of the enamel were observed.
