To evaluate and find the relationship between arch length and incisorial width of maxillary permanent teeth in gender identification.
50 subjects (28 males and 22 females) are selected randomly from outpatients of Saveetha Dental Hospital and community residing in Chennai, India. Subjects’ age group are between 17 to 40 years and selected since attrition is minimal in this age group.1 Subjects are asked to bite the modelling wax to record the bite mark. Fine tipped pen are used to mark the parameter. The arch length and incisorial width of maxillary permanent teeth are measured by using a piece of rope and Vernier caliper. The data is analysed and the relationship between arch length and incisorial width of maxillary permanent teeth of subjects based on their gender will be evaluated.
Mean values for maxillary arch length for males is 55.0mm and for females is 50.77mm. Mean values for maxillary incisorial width for males and females is 9.3214 mm and 8.1818 mm respectively. The study shows significant lower mean value for females when compared to males with highly significant standard deviation.
