| Summary: | 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.
