Objective: Molar-incisor hypomineralization (MIH) is a highly prevalent dental development disturbance caused by disrupted ameloblast maturation. This condition affects up to 44% of children around the world and several systemic conditions have been associated with MIH, including Mouth-Breathing. It is important to show that MIH has multifactorial etiology and is associated with allergic mouth-breathing children. Methods: To evaluate MIH prevalence in MBCS children with positive and negative allergic response to the skin prick test, a cross-sectional quantitative and qualitative comparative assessment was conducted in 23 mouth-breathing children and 25 sex/age-matched siblings. Enamel defects were classified by the modified rate of FDI Development Defects of Enamel. Statistical Student’s t tests were applied to verify the relevance of the data. Results: MIH prevalence showed significant statistical differences in the comparison between molars, independently of individual age (p = 0.01513474). MBCS children under 5 years old had higher statistical prevalence of MIH (p = 0.00594). MBCS children with positive skin reactions to the prick test had higher prevalence of MIH (p = 0,023). MBCS children had statistically significant higher prevalence of demarcated opacity (p = 0.00012). Conclusions: Finally, MBCS children with positive skin reactions to the prick test had higher prevalence of MIH (p = 0,023), indicating that mouth-breathing allergy-responsive children had higher MIH prevalence. Our results corroborate our previous hypothesis that MBCS children have increased MIH prevalence in comparison to their siblings, with statistical significance (p = 0.01513474). Further investigations with larger samples may enhance and confirm the accuracy of our results.
