This article demonstrates the use of micro-CT scanning of the teeth surface for recognizing and evaluating severity of the enamel hypoplasia. To test capabilities of the microtomography versus classical method of evaluation hypoplastic defects of the enamel we selected two human teeth (C, M(2)) showing different types of enamel hypoplasia: linear, pits, and groove. Examined samples derive from archeological material dated on XVII-XVIII AD and excavated in Poland. In the current study we proved that micro-CT scanning is a powerful technique not only for imaging all kinds of the enamel hypoplasia but also allows to perform accurate measurements of the enamel defects. We figure out that contrary to the classical method of scoring enamel defects, the micro-computed tomography yields adequate data which serve for estimating the length of stress episode and length of interval between them.

This study aimed to determine the number of infraorbital foramina in monkeys of the Papionini tribe. The authors performed a μCT analysis of the morphology of the infraorbital foramina. A total number of 52 simian skulls belonged to two macaque species: Macaca mulatta and Macaca fascicularis were used in the study. The number of infraorbital foramina was counted macroscopically and with the use of a magnifying glass. Next, the skull representing the most common morphological type was selected and scanned by micro‐computed tomography (μCT). The Shapiro–Wilk normality test was used in the study. To compare the differences in the number of infraorbital foramen between species, sex and sides, the Mann–Whitney U test was applied. Three infraorbital foramina were present in most individuals from the test group. The Mann–Whitney test revealed no statistically significant difference between the number of foramina on the right‐ and left‐hand side. Likewise, no statistically significant differences between the numbers of infraorbital foramina across sexes were observed. Volumetric reconstructions revealed the presence of separate infraorbital canals for each infraorbital foramen. Craniofacial innervation in macaques is formed by complex branching patterns of cranial nerves. Variability in the number of infraorbital foramina suggests a variable maxillary innervation pattern in these animals. Based on the analysis of volumetric projections, the presence of two labial branches and a single nasal branch of the infraorbital nerve is suggested. Detailed descriptions are supported by quantitative data and μCT evidence.

The aim of this study was to analyse the relationship between childhood socioeconomic conditions and body asymmetry in young Polish women. The study measured fluctuating asymmetry (FA), which refers to small random deviations from perfect symmetry in bilaterally paired body structures. Data were obtained from 620 female students aged from 19 to 25 years recruited from Jagiellonian University in Cracow, Poland. The research was carried out in the period from January 2016 to May 2017. A composite fluctuating asymmetry (cFA) of the women was calculated using five bilateral body traits. The lengths and widths of the women’s ears, lengths of their 2nd and 4th digits and wrist widths of the right and left sides of the body were measured twice using standard methodology. The following data were collected in a questionnaire: degree of urbanization of the woman’s place of residence during childhood, number of older siblings, parental education and woman’s dominant hand. The results showed a tendency for FA to fall with an increase in parental education, and to rise with an increase in number of older siblings. The level of FA was significantly lower in women from rural areas than in those from cities. The results of the study show that FA in early adulthood is significantly associated with socioeconomic status during childhood, and confirm that the level of FA in adulthood may be a good indicator of stress factors in the early stages of development.

In this study, we aimed to identify the differences in body structure between early, average, and late maturing girls, taking into account family characteristics assessing socio-economic and living conditions. This study was conducted in the years 2003 and 2013 in Warsaw, Poland and comprised 788 girls in the age group of 11-19 years. The data were collected using a questionnaire which included parental education and profession, girls' date of birth, age at menarche, and lifestyle characteristics. The measurements included height; weight; skinfolds on arm, under scapula, and on abdomen; arm circumference; and body mass index (BMI). The girls were divided into three groups: early, average, and late maturing. To eliminate the age differences, for each of the examined somatic variable, a "z" score was calculated. We analysed the combined data of both years (2003 and 2013) due to the lack of difference in the mean age at menarche. The primary objective of this study was to assess the relationship between somatic body structure and socioeconomic and lifestyle factors among early, average, and late maturing girls. Early maturing girls possessed higher body weight and BMI. In families with only one child, the age at menarche was found to be the earliest than in families with more than one child. Body weight, BMI, arm circumference, and fatfold thickness was found to be reduced in case of girls whose parents had better education and profession than their peers. Higher levels of stress were associated with higher body mass, greater BMI, arm circumference, and skinfolds in early maturing girls. The associations between body structure with physical activity and family was mainly correlated with body weight and BMI. Socioeconomic and lifestyle factors may be helpful in some levelling of differences in the body structure between girls differing in the age at menarche, especially the level of stress and the education and profession of parents.

In the present study we investigated the impact of respiratory allergy on quality of life in young people, and examined whether socio-economic status modifies the above dependence. The study was conducted in 458 female and 363 male university students, aged 18-25. Information on socio-economic status (SES) was collected using a questionnaire. The occurrence of allergy was determined on the basis of answers to the questions whether the allergy and specific allergens were medically diagnosed. Quality of life (QoL) was based on the Polish version of the SF-36 test. Respiratory allergy or respiratory and food allergy were declared by 19.2 % of women and 19.0 % of men. The prevalence of allergy was higher in students with high SES. The students suffering from allergy obtained lower scores in all domains of QoL, but the differences were statistically insignificant. However, the overall test result in allergic students was significantly lower than that in non-allergic students. Differences QoL were significantly associated with socio-economic variables. In persons with low SES, the differences in QoL between those suffering from allergy and those who did not have allergy were larger than in persons with high SES. The results indicate that the course of allergic diseases is highly dependent on socio-economic status. The prevalence of allergy among students of low status is lower than among those of high status. However, allergy to a greater extent impairs the quality of life of students with low than high SES.
