Abstract

Objective: Molar Incisor Hypomineralization (MIH) is observed on permanent molars as demarcated opacities that vary from creamy-white or yellow to yellowish-brown discoloration. MIH is of systemic origin, usually affecting one to four permanent first permanent molars. The current study was designed to determine the prevalence, pattern, and distribution of MIH in school-going children of United Arab Emirates.
Materials and Methods: A total of 1200 children with 656 boys and 544 girls were included in the study. The children belonged to the age group of 8-12 years of age. The children were examined for prevalence and distribution of MIH. The results were analyzed using SPSS version 20.
Results: The prevalence of MIH was reported at 21.16%. It was seen that MIH is more prevalent in girls when compared to boys, with the p value being <0.001. The mandibular molars had a higher prevalence when compared to the maxillary molars, with the results being statistically significant.
Conclusion: The prevalence of MIH in Arab children in Ras Al Khaimah, United Arab Emirates (UAE) was 21.6%. Mandibular molars are affected more commonly than maxillary molars. Further studies are recommended to better understand the possible etiologies of this condition in children.
