| Summary: | Objectives: To investigate the dental development (DD) in children with
hypodontia and hyperdontia compared to age, gender, and race matched controls.
Materials and methods: A match-pair case control study was conducted among
children aged 5 to 14-year-old, attending the Dental Polyclinic, IIUM, from
December 2011 until September 2014. Willem’s method was used to analyze the
dental age (DA) using panoramic radiograph. The difference between dental age of
hypodontia/hyperdontia children and the controls was analyzed using analysis of
covariance (ANCOVA). The differences between dental and chronological ages (CA)
and the differences in DA and CA with the numbers of missing teeth were analyzed
using t-test. Intraclass correlation coefficient between examiners ranged from
0.98-0.99.
Results: 27 hypodontia and 12 hyperdontia samples were recruited and compared
to a total of 78 matched controls. Both male (n=12) and female (n=15) hypodontia
children had statistically significant delay in DD (p=0.000). There was no significant
difference in the DD of male (n=7, p=0.811) and female (n=5, p=0.235) in
hyperdontia children compared to the matched controls. No differences were
observed between DA and CA with the number of missing teeth.
Conclusion: Unlike hyperdontia children, hypodontia children showed delayed DD
in comparison to age, gender, and race matched controls. There was no association
between magnitudes of dental development delay in hypodontia children with the
number of missing teeth. This study provides valuable baseline information for
provision of better treatment planning for those hypodontia and hyperdontia
children that may involve inter-disciplinary management |
