Abstract

Objectives: To assess oral health, caries prevalence, and subsequent complications among recently arrived refugees in Germany and to compare these findings with the German resident population.

Methods: This multicenter cross-sectional study recruited 544 refugees aged 3-75+ years; they were examined at ten registration institutions in four federal states in Germany by two calibrated dentists. The refugees were screened for caries (dmft/DMFT) and its complications (pufa/PUFA); this data was compared to the resident population via the representative national oral health surveys).

Results: The deciduous dentition of the 3-year-old refugees had a mean dmft value of 2.62 ± 3.6 compared with 0.48 dmft in the German resident population, and caries increased to 5.22 ± 3.4 for 6-7-year-olds (Germany: 1.73 dmft). Few refugee children had naturally healthy teeth (7% in 6-7-year-olds, Germany: 56%). In the permanent dentition, the gap in caries prevalence between refugees and the German population decreased with age (35-44-year-olds: 10.55 ± 7.1 DMFT; Germany: 11.2), but refugees exhibited more caries defects (35-44-year-olds DT = 3.13 ± 3.0; Germany: 0.5). German residents had more restorations (35-44-year-olds FT = 4.21 ± 4.6). Regarding complications, the 6-7-year-olds exhibited the highest pufa index (0.86 ± 1.4) which decreased in adolescence (13-17-year-olds, 0.18 ± 0.6) and increased in adults (45-64-year-olds, 0.45 ± 0.8).

Conclusion: The refugees had high caries experience, often untreated caries teeth and more complications compared with the German resident population, especially in children. Closing this gap by extending preventive systems to the refugees would decrease future treatment needs.

Clinical relevance: European countries should be prepared for the higher dental treatment needs in recent refugees, especially in children.
