Background: Hypomineralization is a developmental abnormality of enamel which occurs due to disturbances of ameloblast function. Objectives: The aim of this research was to investigate the rate of dental development in Malay children with Molar Incisor Hypomineralization (MIH) compared to age and gender matched controls. Materials and methods: A matched-pair case control study was conducted on children aged 7 to 14 attending Polyclinic, Kulliyyah of Dentistry, International Islamic University Malaysia (IIUM), from February 2013 until April 2014. MIH was determined based on criteria from EAPD seminar, 2003. Dental development was determined using dental age score from Willem's method on orthopantomogram (OPG) on 24 children (13 girls, II boys) compared with 24 control groups, case-matched for gender and age. Intra and Inter- examiner reliability was tested with Kappa statistic; Intra and inter examiner reliability were 0,988 and 0.848 respectively. This research was approved by the IIUM Research Ethic Committee. Results: Matched paired T-test showed that dental age (DA) on MIH patients was statistically higher than chronological age (CA) (p=0.007). The differences between DA and CA in MIH boys were significant (p= 0.012) while the girls' results were not significant (p= 0.121). Both girls and boys in control groups showed differences between DA and CA were not significant (p=0.354, p=0.194) respectively. Conclusion: The rate of dental development in children with MIH is higher compared to control group. Dental age of MIH boys is higher than girls. These findings have implications to optimize management of dental growth and development in children with MIH.
