Pak Oral Dental J Jan ;37(1):161-3.

The aim of this cross sectional study was to determine the frequency of colour vision deficiency (CVD) among students of Sardar Begum Dental College, Peshawar, Pakistan. This research has significance in restorative dentistry particularly in Prosthodontics and Operative, as the ability of a dentist to perceive colour is important for accurate shade matching, so as to produce more aesthetic restorations and satisfy the patient’s aesthetic demands. A total of 240 participants were recruited in this study, out of which 145 were females and 95 were males. Each subject was tested for CVD using Ishihara plates. Association of gender with CVD was insignificant using Chi square test. About 9( 3.75% ) students found out to be colour blind, among which 7(7.95% ) were male and 2 (1.39%) were females respectively. The male to female distribution showed a higher frequency amongst males compared to female but the overall relation of CVD with gender found to be insignificant.
