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<0.001).

Conclusion

MIH was common among a
group of 7-9 years old children, Istanbul.
