In recent years, global conflicts have increased the number of displaced individuals, with a notable rise in asylum seekers and refugees in Iceland. This study aimed to assess the dental hygiene practices, oral health status, and dental caries experience (dmft/DMFT) of children and adolescents aged 0-18 seeking international protection in Iceland. Key findings include that over half of the children had not attended a dental appointment in at least two years, with dental pain being the most common reason for previous visits. The mean dmft for six-year-olds was 4.33, and the mean DMFT for twelve-year-olds was 2.55. Additionally, 61.4% of the children were affected by dental caries, and 20.6% had active dental infections at the time of examination. The high prevalence of dental issues, including gingivitis (37.8%) and dental erosion (12.3%), points to a critical need for enhanced preventive measures and targeted dental care services. These findings highlight the urgent requirement for a comprehensive and integrated approach to dental healthcare for these children, whose conditions are notably poorer compared to their peers in other Nordic countries and beyond.
