Background: The objective of this investigation was to assess the oral health (OH) of Bosnia and Herzegovinian adolescents in relation to differences and socioeconomic status (SES). Methods: This cross-sectional study included 306 school children from high schools located in the Tuzla Canton (Bosnia and Herzegovina). The sample consisted of 183 females and 123 males between 15 and 18 years old (mean of 16.82 years old). The study was conducted between December 2019 and March 2020, via an Annex 8 questionnaire from the World Health Organization (WHO), which collected information on OH behaviours, self-perceptions of oral health and dietary factors responsible for the OH of each subject. SES was categorized using five variables (occupation, education, income, place of residence and number of family members). Cross-tabulations were evaluated according to sex and socioeconomic status (SES) via the chi-square test. Results: Over 40% of the participants consumed sweets, cakes and biscuits on daily basis, whereas 41.5% of the participants visited a dentist only in the case of pain. The consumption of sweets (p = 0.024) and cakes and biscuits (p = 0.011) on a daily basis was significantly greater in female adolescents than in male adolescents. Compared with male adolescents, female adolescents reported occasional toothaches more frequently (p = 0.001) and were more dissatisfied with their dental appearance (p = 0.008) but presented a greater frequency of flossing (p = 0.001) and toothbrushing (3–5 times a day) (p = 0.0001). There was no association between the different levels (below average, average, above average) of SES and factors affecting OH status of adolescents. Conclusions: The study revealed significant sex differences in several factors affecting OH status and revealed no relationship between SES and OH behaviours or between perceptions and risk factors affecting OH in 15–18-year-old adolescents. Data obtained from this study might help in the creation of new OH prevention programs aimed at improving the OH status of adolescents in Bosnia and Herzegovina.

Introduction: Socioeconomic changes have a significant impact on the health of the population. Socioeconomic development of society is one of the basic determinants of the health condition and needs of the individual and in the population as well. Aim: To explore the existence of differences in indicators of oral health status between the displaced persons and domicile population, considering the socioeconomic status (SES) of the respondents. Patients and Methods: A total of 310 people, aged 35-44 (mean 40.19 ± 3.60), were interviewed and examined, with 157 of them in a subsample of domicile inhabitants and other 153 respondents in displaced persons subsample. The SES of respondents was determined using a survey. After conducted examinations in study participants, determined results were recorded as dental status (DMFT Index), and periodontal status (CPI Index). Results: There was a significant difference in the mean value of caries existence between displaced persons of low and middle SES. In domicile inhabitants, there were no statistically significant differences in mean values of caries existence between the individuals with low and middle SES, while the differences existed between the individuals with low and high and between the middle and high SES. Domicile inhabitants with high SES had significantly less carious lesions than those with lower SES. Domicile inhabitants with high SES had significantly fewer extractions and more teeth with fillings. Conclusion: People with low SES have worse oral health status. Displacement and low socioeconomic status significantly influence the state of oral health.
