“…A total of 400 CSHCN were included based on the pilot study, which also satisfies the minimum required study population criteria in MIH frequency studies. 34 The overall prevalence of MIH in the present study was 24.5%, as similarly reported by Rizk et al, 25 although among normal Saudi children. In contrast to this, Allazzam et al 5 showed a prevalence of 8.6% MIH among 8 to 12-year-old children visiting the Pediatric Dental Clinic.…”

“…The present study result showed that upper permanent first molars were the most frequently affected teeth, and demarcated opacity was the most frequent type of MIH as reported by previous studies. 14 , 16 , 20 , 21 , 24 , 25 The prevalence of posteruptive enamel breakdown, atypical restoration, and tooth loss were slightly higher compared to the previous studies. 6 , 9 This may be due to the inclusion of older age children in the present study.…”

“… 15 - 18 The global prevalence of MIH varies from 2.8% to 40% depending on the population studied and diagnostic criteria used to identify MIH. 5 - 11 , 19 - 25 A few point prevalence studies conducted in Saudi Arabia among children without special needs have reported an MIH prevalence of 8.6% to 25%. 5 , 25 …”

BACKGROUND: Molar incisor hypomineralization (MIH) is a frequently encountered oral condition that varies from mild opacities to posteruptive enamel breakdown. No previous published studies have investigated the frequency of MIH and associated risk factors among children with special health care needs (CSHCN) to our awareness. OBJECTIVES: Assess the frequency of MIH and associated risk factors among CSHCN. DESIGN: Cross-sectional. SETTING: Schools in provincial city of Saudi Arabia. PATIENTS AND METHODS: The study was conducted among 400 (180 boys and 220 girls) special needs children. Diagnosis of MIH was according to the European Academy of Paediatric Dentistry criteria. MAIN OUTCOME MEASURE: Result of logistic regression analysis that assessed the association between MIH prevalence and associated prenatal, perinatal, and postnatal factors. SAMPLE SIZE: 400 (180 boys and 220 girls) special needs children. RESULTS: Among 400 CSHCN, 98 (24.5%) presented with MIH. Children with multiple disabilities had a 3.89 times greater risk of MIH (95% CI: 1.91–6.19, P =.002). Children with positive prenatal factors had an adjusted odds ratio (aOR) of 2.31 times for MIH (95% CI: 1.22–4.73, P =.012). Children with a childhood infection history had an aOR of 2.43 times for MIH (95% CI: 1.31–5.85, P =.014). Children with a breastfeeding history >18 months had an aOR of 3.73 for MIH (95% CI: 1.62–8.60, P =.002). Permanent maxillary first molars were the most frequently affected teeth, and demarcated opacity was the most frequent MIH type. CONCLUSION: MIH should be recognized as one of the prevalent oral health problems among CSHCN to prevent tooth mortality. LIMITATIONS: A cross-sectional study cannot establish a causal relationship. CONFLICTS OF INTEREST: None.
