Abstract

AIM: The aim of this study was to determine the prevalence and severity of molar incisor hypomineralisation in 6-12-year-old children living in Northern Poland. MATERIALS: The study involved 1437 children aged 6 to 12 years.

All surfaces of the index teeth were examined and diagnosed MIH according to Weerheijm et al. criteria. The severity was recorded as mild or severe according to EAPD criteria. CONCLUSION: In North Poland the prevalence of MIH is 6.43%.
