Orofacial Functions in Individuals With and Without Molar Incisor Hypomineralization

Molar incisor hypomineralization (MIH) is a qualitative developmental defect of the enamel with a complex, multifactorial nature and a significant genetic component that predominantly affects the permanent first molars and, occasionally, the permanent incisors. Individuals with MIH have a compromised stomatognathic system manifested by muscle hyperactivity under postural and dynamic conditions. However, there is a gap in knowledge on the specific functional abnormalities that these individuals experience. Early identification and intervention, with a focus on the prevention of orofacial dysfunctions and deviations in facial growth and development, are aspects of the utmost importance. Therefore, the aim of the proposed study is to perform a comparative analysis of orofacial functions with an emphasis on breathing and chewing patterns in individuals with and without MIH. Methods and Analysis: Assessments will be performed using the Nordic Orofacial Test - Screening (NOT-S). Descriptive statistics will be performed and comparisons will be made using the chi-square test, adopting a 5% significance level.
