We presented the prevalence of MIH in Dubai/UAE for the first time, which represents a developed Middle Eastern city and compared it to results obtained from Greifswald/Germany, which represents a developed European city. The results have shown that the prevalence of MIH in Dubai/UAE is higher than Greifswald/Germany. However, in comparison to the literature, the prevalence of MIH in Dubai is lower than other Middle Eastern cities. Furthermore, we have shown that there is a higher caries level associated with MIH in Dubai. This is also true in Greifswald, Germany and other international studies. In addition, we have reported the prevalence of caries and fluorosis in Dubai and compared them to Greifswald and the previous studies in Dubai. Nevertheless, caries values presented in this study and previous studies indicate that strong attention is required from health authority to this topic. This research provides a strong and comparable source of information on the prevalence of MIH in Dubai for other studies, since it followed strictly all methodological and clinical standards suggested for the assessment and diagnosis of MIH, which are the EAPD criteria. The findings presented in this study require particular attention from the local health authorities and general practitioners for such developmental defect to facilitate early and adequate diagnosis and treatment. This could be achieved by implementing continuing education courses on MIH detection, diagnosis, and treatment for general practitioners. Furthermore, this study has the potential to trigger new studies that would help in understanding the MIH etiology.
National oral health survey on refugees in Germany 2016/2017: caries and subsequent complications
(2020)
Objectives To assess oral health, caries prevalence, and subsequent complications among recently arrived refugees in Germany and to ompare 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 presentative 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.
