Objectives: The aim of this study was to determine the prevalence and distribution of molar incisor hypomineralisation among Kurdish children in Sulaimani City, Iraq.

A cross-sectional survey was carried out on primary school students in Sulaimani City. A total of 2346 Kurdish children aged 7 to 9 years old were examined; 1194 (50.9%) males and 1152 (49.1%) females, enrolled in 20 primary public schools. The index teeth were evaluated using the European Academy of Paediatric Dentistry (EAPD) criteria for MIH.

The prevalence of MIH was found to be 18.2% where no statistically significant association was found with age or gender (P>0.05). Multiple teeth involvement (13.2%) was more common than a single molar involvement (5.1%). The mean number of the affected index teeth with MIH per affected child was (3.1). Mild defects were present in 64.1% of the affected teeth with demarcated creamy-white opacities were the most common finding (33.3%).

It’s been found that MIH is a prevalent pathology among Kurdish children in Sulaimani City which could result in a large number of children continuously seeking professional dental treatment. Therefore, dental practitioners who deal with child patients could encounter such cases and should be aware of the treatment choices and management protocols for coping with this particular condition.
