Aim: To conduct a comprehensive analysis of the oral health status of this vulnerable population in order to collect objective data that will contribute to the development of effective strategies for maintaining and improving oral health in wartime conditions. Material and Methods: This epidemiological study was carried out within the initial 6 months of the full-scale invasion of the country. The oral health indices of 1050 internally displaced children, aged 3 to 17 years, seeking dental care at the Municipal Children Dental Clinic in Poltava, were analyzed. Results: The total sample comprised 620 children aged 6-11 years (mean = 8.5, SD = 0.76), with a gender distribution of 52% boys and 48% girls. The par ticipants were divided into three age groups: Group I (6-7 years), Group II (8-9 years), and Group III (10-11 years). The average prevalence of dental caries, as measured by the dmft + DMFT index, was 76.5%, with prevalence increasing with age. Specifically, the prevalence of dental caries based on the dmft index was lower in children of Group III (66.6%) compared to Group I (79.49%). Conclusions: The analysis of the oral status among internally displaced children aged 6-11 years revealed higher dental caries prevalence and intensity compared to local children. Notably, children aged 6-7 years showed a high rate of caries in temporary teeth.
