[Dental caries in children aged 7 and 12 years in the Province of Poznan]. / Próchnica zebów u dzieci w wieku 7 i 12 lat zamieszkalych na terenie województwa Poznanskiego.

The authors present the results of stomatological epidemiological studies in the Province of Poznán in 1987 for establishing the prevalence of dental caries in children aged 7 and 12 years. The assessment was done using the index of caries prevalence, value of the mean DMF-H and dmf-h indices, and their components. In both studied age groups a high prevalence of caries was found, reaching 90% in children aged 7, years and 80% in those aged 12 years. The intensity of caries in children aged 7 years measured by the index DMF-h+dmf-h (mixed teeth) was high--4.99. The intensity of caries was higher in children from rural areas (5.43) than in those from urban areas (4.455). The mean value of DMF-h was 0.49 for the whole population studied, and 0.41 for urban children and 0.56 for rural children. The mean DMF-z value in children aged 12 years was below 3.0 (2.34), and it was higher in children from rural areas (2.96) than in those from urban areas. The values of these indices were influenced mainly by high mean numbers of milk and permanent teeth with active caries. In the studied population a small number of filled teeth was noted.

[The condition of teeth in adult population aged 35-44 years living in a small town and in villages in the Province of Poznan]. / Stan uzebienia doroslej ludnosci w wieku 35-44 lat zamieszkalej w malym miescie i na wsiach województwa Poznanskiego.

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.

[Requirements for prosthetic treatment of adults aged 35-44 years in the Province of Poznan]. / Zapotrzebowanie na leczenie protetyczne doroslych w wieku 35-44 lat w województwie Poznanskim.

Stomatological examination of a group of 120 adults aged 35-44 years living in the Province of Poznan showed considerable loss of teeth (mean loss--7 in towns and 9 in villages). It was found that a small percent of these adults had prosthetic replacements. The greatest requirements were for partial lower prostheses and upper partial prostheses. Generally, greater loss of teeth was found in the rural population compared with the urban one.
