ABSTRACT: Aim To our knowledge, the prevalence and aetiology of molar-incisor hypomineralisation has not been discussed nor investigated in Turkish children in Istanbul. Therefore the aim of the present study is to investigate the prevalence and aetiology of MIH in a group of children in Istanbul. Design Between April and July 2007, a retrospective clinical study was initiated at the Dept. of Paediatric Dentistry, School of Dentistry, Yeditepe University, Istanbul, Turkey. A total of 147 children aged 7-9 years visiting our clinic were examined by two calibrated paediatric dentists (kappa: 0.89). The examiners used the criteria for the diagnosis of demarcated opacities, post-eruption breakdown, atypical restorations, and extracted PFMs due to MIH developed by Weerheijm et al. Results In the present study, prevalence of MIH was 14.9%. Of the 22 children affected with MIH, 17 (77.2%) had only demarcated opacities, but no breakdown or atypical restorations. Regarding diseases in the first 3 years of life, 55% of MIH and 19.4% of non-MIH children had a disease history. 27% of MIH children had suffered from upper and lower respiratory tract infections including bronchitis. This was significantly different from non-MIH children (p<O.001). Conclusion MIH was common among a group of 7-9 years old children, Istanbul. KEYWORDS: Hypomineralisation, Molars, Incisors, MIH, Prevalence.
