Aim: To investigate whether sexual dimorphism can be established
by odontometric study of permanent maxillary canine teeth as well as
inter-canine width in north Indian population.
Study design: The study was carried out at department of oral and
maxillofacial pathology, King George’s Medical University, Lucknow, India on
students and patients reporting at OPD. Out of total 180 subjects examined 90subjects were female and 90 were male. Impressions of the upper arch were made
using alginate and casts poured in dental stone. The mesiodistal diameter of
the crown of permanent maxillary canine both on right and left sides and
inter-canine width were measured. From these measurements, maxillary canine
index was calculated. The percentage of sexual dimorphism was assessed for all
the parameters.
