Historically speaking, after World War II Poles were forced to migrate from central and eastern parts of pre-war Poland to south-western post-war territories of the country. In this context, the comparison and assessment of the state of dentition of seniors in south-eastern and south-western Poland born between 1935 and 1950 merits analysis.

Aim of the study:
To estimate similarities and differences between seniors’ dentition in two socioeconomically diverse regions of Poland.

Material and methods:
The research group comprised 202 elders, participants of the “third-age” university, who were divided into two regional groups: Wroclaw (south-western Poland) and Rzeszow (south-eastern Poland). The mean age was respectively 68 and 71 years. The clinical examination chart contained a standard dental diagram, in which missing teeth and type of prosthetic restoration were marked.

In the Wroclaw group, the average number of preserved teeth was significantly higher than in Rzeszow, 15.25 and 11.59, respectively (p<0.01). Significantly lower number of maxillary teeth was found relative to the age of men from Wroclaw. Bi-directional analysis of variance of the combined results of the study groups showed that the place of residence had a significant influence on the number of teeth preserved regardless of the age of the subjects. Edentulousness was found to be more common among the inhabitants of south-eastern Poland.

Seniors from Wroclaw had a higher number of teeth in both of the dental arches, in comparison with their peers from Rzeszow. The statistical analysis indicates the lack of dimorphic differences – both men and women had a similar number of preserved teeth. The number of teeth in the maxilla is lower than in the mandible.
