Abstract
Dentists having defective color vision may be unaware of their defect or may have problems in perceiving color as normal
vision dentists do. People who are "color vision defective" tend to be missing some of the color-sensitive cones, so these
colors will appear darker. The aim of the present study is to 1. estimate the number of dental students/ personnel having
problems in color discrimination based on a color blindness test 2. To refer the students/ personnel to a specialist for
confirmative diagnosis. 3. To provide alternate options for shade selection to the same. Dental students, dental teachers and
dental technicians/ dental auxiliaries were randomly selected for the study, with a sample size of 400 with age range of 17 to
35 out of which 200 were males and 200 females. An Ishihara color blindness test (numbers made up of color dots) was
conducted to screen the dental personnel for color defective vision in the same room and in the same light source. 5% of the
male and 0% of female dental personnel/ students were found to be color vision defective. Counseling to such students and
personnel required to take assistance in appointments of shade selection / matching.
