| Abstract | Objective: To define the prevalence of Molar Incisor Hypomineralization (MIH) in Brazil since the reports
ranged from 2.5% to 40.2%. Material and Methods: We studied 407 children from 7 to 14 years of age.
MIH was measured using the European Academy of Paediatric Dentistry criteria of 2003. Clinical data were
collected by a calibrated dentist (Kappa=0.88) and included affected teeth and degree of MIH severity
(mild/severe). Mild MIH cases were considered when the tooth presented demarcated opacity ≥ 1.0mm,
without any loss of structure. While severe cases were defined by teeth in which loss of structure was
present, or past or current lesion that required treatment, or presence of atypical restorations. In addition,
published data (nine studies) reporting MIH in Brazilians were identified, and the heterogeneity of these
studies was tested (I2 index/ p≤0.01). Results: In the original sample studied, the majority of patients were
males (55.3%; n = 225), with an average age of 10.1 years (± 2.1 years). The prevalence of MIH in this
group was 14.5% (59 affected in 407), and most of the affected teeth had a mild degree of alteration (77.4%
or 202 in 261 teeth). Conclusion: A meta-analysis including nine published reports, and our original data
showed that MIH prevalence in Brazil is 13.48 (95% CI, 8.66% -18.31%). | pt_BR |
