A comparative study of cranafacial morphology in Malaysian aborigines and Malays.
A comparative study of cranafacial morphology in Malaysian aborigines and Malays.
Abstract
In clinical practice, cephalometric analysis is valuable in assessing facial and dentoskeletal
relationships. It provides a measure of skeletal morphology and allows correlations of
skeletal factors of malocclusion in and among populations. This study aims to provide
cephalometric findings of a selected Orang Asli population ofKelantan particularly the
Jahai tribe and compare values with other ethnic groups. It is a cross-sectional study
involving 68 selected adults of the Jahai tribe. Cephalograms of adults aged 18-45 years
were taken using a standard Orthopantomograph (OPT) machine. These cephalograms
were individually traced by manual method using tracing paper and 2B pencil. The
tracings of the cephalograms were then analyzed according to Steiner's analysis and SPSS
Version 11.0. The analyses of each measurement characteristics of the sample were
compared with the standard accepted values for other ethnic groups. It was found that the
Jahai tribe of Orang Asli population in Kelantan has a more prominent bimaxillary
protrusion compared with other ethnic groups. These findings confirmed that there were
significant variations in the craniofacial features of Orang Asli population, particularly the
Jahai tribe when compared with the other ethnic groups. These measurements served to
complement existing incomplete data of craniofacial measurements in our local data bank.
Thus, this tiny effort has a potential role in the completeness of craniofacial analyses of the
local Orang Asli population. The information collated can further enhance valid
comparisons and establish norms among tribes in Malaysia and in the Asia pacific region
