Orofacial functions with emphasis on breathing and chewing patterns in individuals with and without molar incisor hypomineralisation: observational study protocol conducted in a dental clinic in Brazil
Introduction Molar incisor hypomineralisation (MIH) is a qualitative developmental defect of the enamel with a complex, multifactorial nature and a significant genetic component. Individuals with MIH have a compromised stomatognathic system manifested by muscle hyperactivity under postural and dynam...

| description | Introduction Molar incisor hypomineralisation (MIH) is a qualitative developmental defect of the enamel with a complex, multifactorial nature and a significant genetic component. 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. The secondary objective is to assess whether dentin hypersensitivity and the severity of MIH lesions are associated with alterations in orofacial functions.Methods and analysis Assessments will be performed using the Nordic Orofacial Test-Screening (NOT-S). Descriptive analyses will characterise the sample. The Shapiro-Wilk test will assess normality. For normally distributed data, analysis of variance and Tukey’s post hoc test will be used. For non-normal data, the Mann-Whitney U test will be applied. The χ2 test will analyse categorical variables and compare NOT-S domains between groups. Potential confounders (eg, age, sex, socioeconomic status) will be controlled through stratification or as covariates. Logistic and Poisson regressions will model associations for categorical and count-based outcomes, respectively. Statistical significance will be set at p<0.05.Ethics and dissemination This protocol has been approved by the Human Research Ethics Committee of Nove de Julho University (certificate number: 83969924.2.0000.5511; approval date: 22 November 2024). Participants will agree to take part in the study by signing an informed consent form. The findings will be published in a peer-reviewed journal. The collected data will be available on request.Trial registration number NCT06692257. |
