The Pearson Chi-Square test and Independent Sample T-test was used to analyse the relationship between age, sex, race, and the shape and length of the mandibular notch. A 95 % confidence level was adhered to for all statistical tests.
The principle investigator assessed the morphological and morphometric parameters of the mandibular notch on two separate occasions to ensure reliability and validity.
Morphology of the mandibular notch. The round shape was most prevalent in 44.2 % of the sample, this was followed by the wide (36.0 %), sloped (11.3 %), triangular (6.3 %) and quadrilateral (2.2 %) shapes, respectively (Table II).
Length of the mandibular notch. The length of the mandibular notch was greater in males than females, with a length of 28.07 mm and 26.77 mm, respectively (Table II).
