Background: Molar Incisor Hypomineralization is a clinical challenge for pediatric dentists worldwide with an uncertain prevalence and unknown etiology. This present study aims to assess the prevalence of Molar Incisor Hypomineralization among a group of children treated with asthmatic drugs during their first three years of life.
Methodology: The study included 160 asthmatic patients (aged 8 to 12 years old) attending the outpatients' pediatric pulmonary unit of two Pediatric Hospitals. A clinical examination was performed to diagnose the presence or absence of Molar Incisor Hypomineralization and its severity. Data about medical history, duration, and types of asthmatic drugs were obtained from the parents and the hospital's medical records.
Results: Among the study population, 23.1 % had Molar Incisor Hypomineralization, where 15% were mild, 4.4% were moderate, and only 3.8 % were severe cases. The prevalence of Molar Incisor Hypomineralization was higher in males (25.2 %) than in females (19.3 %). However, all the severe cases were found among females. All cases took corticosteroids in combination with beta-2-agonist and/or antihistamines.
Conclusion: Children treated with asthmatic drugs - especially corticosteroid inhalers-during their first three years of life showed an increased risk for MIH with a higher prevalence among males than females.
