Objectives: This research article focuses on prediction of age on
the basis of maximum ramus breadth, minimum ramus breadth,
condylar height, projective height of ramus and coronoid height.
(Linear regression analysis). However, it also determines sex of
individual on the basis of discriminant function analysis using
Fischer exact test using maximum ramus breadth, minimum
ramus breadth, condylar height, projective height of ramus and
coronoid height.
Materials & Methods: The orthopantomograms of 200 subjects
were taken from Planmeca Promax-dimax4 OPG machine at 66
Kvp, 8mA and exposure time 16 sec. All the measurements are
done on digital orthopantomograms using Planmeca Romexis
3.2.0R software. The measurements of the mandibular ramus will
be subjected to discriminant function analysis.
Results: The study sample consists of 200 subjects aged
between 8 to 82 years with a mean age of 38.21±17.12 years. The
persons correlation coefficient (r) between age and minimum
ramus breadth was not significant correlation however the
maximum ramus breadth, condylar height, coronoid height
and projective height were directly associated with age and
demonstrate a significant positive relation in maximum ramus
breadth, condylar height, coronoid height and significant positive
relation in projective height. The maximum ramus breadth, min
ramus breadth, condylar height, coronoid height and projective
height values were greater in males than females. The difference
in maximum ramus breadth, minimum ramus breadth, condylar
height, coronoid height and projective height values in males and
females were statistically significant (P<0.05).
Conclusions: Mandibular ramus can be a useful tool for age and
sex determination in forensic science. Thus, medicolegal cases
having age and sex issues can be resolved with measurements of
mandibular ramus if panoramic radiograph is available.
