Oral health burden and behavioural determinants of dental caries among Ukrainian civilians attending humanitarian dental missions in 2025 and 2026: a two-wave cross-sectional cohort study in Korosten and Ternopil
This two-wave cross-sectional study of Ukrainian civilians in 2025 and 2026 reveals a severe caries burden dominated by missing teeth, identifying that patients in the geographically exposed Korosten region face a 32% higher burden than those in Ternopil, while twice-daily brushing significantly reduces caries severity.
