Abstract
Background: Molar incisor Hypomineralization (MIH) has become a more widespread problem around the world, while its prevalence in Egypt is underestimated with no data on its correlation to Hypomineralization of Second Primary Molars (HSPM). Aim: Estimate the prevalence of MIH and HSPM in Egypt, investigate the possibility of HSPM being a predictive factor for MIH, and the probable etiological factors for MIH. Material and Methods: Three hundred and seventeen healthy children aged seven to ten years old were dentally examined for Molar Incisor Hypomineralization and Hypomineralization of Second Primary Molars and all potentially correlated etiological factors. Both MIH and HSPM were scored according to The European Academy of Pediatric Dentistry (EAPD) criteria for Molar Incisor Hypomineralization. Results: MIH was found to be prevalent in 18.3% of the study population, with no significant gender differences (8.8% girls and 9.4% boys) and a mean age of 8.28. Molar Hypomineralization was more prevalent than Molar Incisor Hypomineralization. The risk of incisors affection was about half that of molars affection, and the incidence of MIH was greater in maxillary teeth than in mandibular teeth. HSPM showed a prevalence of 7.6% and was proven to be a predictor factor for MIH (P< 0.001). Several etiological factors have been significantly correlated to MIH during childhood, such as pneumonia and tonsillitis, as well as maternal hypertension, anemia, using insulin and anti-hypertensive medicines during pregnancy. Conclusion: Hence the prevalence of MIH has been steadily rising over the past few decades, prevention and early management will be achievable with the diagnosis of HSPM and dental follow-up for kids with correlated variables.
