CORRELATION BETWEEN SOFT TISSUE AND SKELETAL PROFILE OF DEUTERO-MALAY INDONESIANS
Introduction: The skeletal and soft tissue profile is important in establishing diagnostic and planning an orthodontic treatment. It has been assumed that different ethnic group or race has different facial profiles. The purpose of this cross sectional study was to know the correlation between the convexity degree of skeletal and soft tissue profiles.
Materials & Methods: A sample of 50 cephalometric radiographs of untreated individuals (31 females, 19 males) was obtained. Criteria for sample selection comprised: absence of interproximal caries / filling, aged over 18 years, never undergone orthodontic treatment, no tooth deformity, had Deutero-Malay Indonesian ethnicity , presence of complete teeth from the left first molar through the right first molar with, both on the upper and lower jaws,. The following angular measurements were performed on lateral cephalograms: skeletal convexity degree was represented by N-A-Pog, and soft tissue profile was determined as n-sn-pog.
Results: The mean values for skeletal profile convexity were : 167,37o ( males ), 166,55o ( females ); and for soft tissue profile convexity were : 159,05o (males) and 162,77o (females).
Correlation: By using correlation test, it showed there was a strong correlation between skeletal and soft tissue profile both on males and females.
