Prevalence, Severity and Treatment Needs of Molar Incisor Hypomineralization Among a Cohort of Lebanese Children: A Cross-Sectional Study
Abstract
Highlights What are the main findings? Considerable MIH prevalence of 17.14% among study cohort. Although males exhibited a greater number of affected teeth and increased severity, these differences were not statistically significant. What are the implications of the main findings? Prevalence rate highlights MIH as significant oral health concern that warrants systematic public monitoring. Early identification is essential to apply preventive strategies and early treatment approaches to avoid MIH cases from progressing into severe conditions that require invasive procedures. Abstract Objectives: The aim of the study was to assess the prevalence, severity and treatment needs of molar incisor hypomineralization (MIH) among a cohort of children in Lebanon. Methods: A cross-sectional study was performed in Akkar district in northern Lebanon on 1237 school children between 10 and 12 years old (mean age 11.11 ± 0.80 years) who were recruited from eight private schools. Clinical evaluations were performed after teeth cleaning and drying using sterile gauze. Examiners assessed all teeth present in the oral cavity using the MIH index of the EAPD. If MIH was diagnosed, a further grading was made according to the MIH-TNI index. Results: In total, 212 children (17.14% [95% CI:15.0, 19.2]) were diagnosed with MIH. Of these, 200 children with completed documentation were included in the further statistical analysis. Out of the affected cases, mild lesions were the most common at 41% (n =…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 1,237 participants or records.
