Muscle disorders were most frequently diagnosed in the group of Polish young adults, and the prevalence of the disease did not differ across similar groups of young people.

Background. Radiographic diagnostics in dentistry is one additional examination which facilitates an accurate clinical diagnosis and, as a result, the initiation of appropriate treatment. Despite various limitations, functional panoramic radiograph (OPG) images of the temporomandibular joints (TMJ) provide a great deal of valuable information and seem to be the first-choice modality in the diagnosis of temporomandibular disorders.

Face proportions are under constant evaluation during prosthetic or surgical diagnostics and treatment. The aim was to evaluate the proportions of the faces of young Polish women as compared with other ethnic groups. Materials and methods: The evaluation included 60 photographs of the faces of women, average age 17.9 years. En face images were made with the camera lens situated at the same distance from the photographed subjects. Using Adobe Photoshop software, midsaggital and even anthropometric points were determined in the photographs and then the distance between these points was measured. Four relationships between vertical measurements, 3 between horizontal measurements, and 4 proportions between vertical and horizontal measurements were calculated. The results were evaluated in comparison with the golden ratio (1.618) and the measurements performed for native Americans and Latin American beauty contests winners described in the relevant literature. Results: The result for the average vertical face proportion value of the examined women was close to the golden ratio (GR) and amounted to 1.592 for the proportions between nasion-stomion and stomion-gnation (98% of GR) and 1.372 for nasion-subnasale and subnasale-gnation (85% of GR). Average measurement results for young Polish women's faces were not statistically significantly different for 6 out of 11 relationships under evaluation as compared with the population of native American females and only 2 face proportions were the same as for beauty contests winners from Latin America. Conclusion: Face proportions of young Polish women were different from those of the females living in the American continent.

Background. the amount of low-ph food and drink consumed by young people continues to increase, resulting in an increasing number of people with dental erosion. Objectives. the aim of the study was to use the bewe index to assess the level of dental erosion of young Polish adults. Material and methods. Plaster casts of the maxilla and the mandible and intraoral photographs were taken from volunteers 16.7 to 19.3 years of age and evaluated. they were examined for the presence of symptoms indicating the occurrence of erosive processes. the basic erosive wear examination (bewe) index was used to record the lesions. one person evaluated all the models and pictures after prior calibration. Results. the bewe index was evaluated on 251 pairs of models and images. erosion symptoms were found to occur in 43.43% of the entire study group, representing 109 examined subjects. with most erosion symptoms, the lesions consisted of small amounts of tissue loss in one of the examined sextants. there was a slightly higher prevalence of erosive lesions on the male tooth (45.59%) than on the female (42.62%), with no statistical significance. the value of the cumulative bewe index for individuals varied from 0 to 3, being 0 to 2 in 98.01% of cases (no risk of erosion) and 3 in 1.99% (low risk). Conclusions. the risk of erosion among the studied adolescents was at a similar level as in other countries and occurred slightly more often in men than in women.
