Abstract
The objective of this study was to assess the difference in accurate perception of tooth shades between
the house officers with prior clinical experience and the dental students without any clinical experience.
This cross sectional study was conducted in the Prosthodontics department at Islamic International
Dental Hospital, Islamabad. The study duration span was of 6 months (September 2018 - February
2019). A total of 80 participants were selected using convenience sampling and divided in two equal
groups (one group with 40 students and another with 40 house officers). A simple shade matching
exercise was conducted and the results were registered on to a well-structured proforma. The eighty
participants, including 21 males and 59 females, ranged in age from 19 years up to 24 years with a
mean age of 21.60 years and standard deviation of 1.62. Ten participants from Group 1(undergraduate students) were able to match shade successfully in comparison to twenty seven of the Group 2
participants (house officers). Chi-square test was applied to determine the significance of clinical
experience with successful shade matching obtained by the subjects. When the final scores were correlated among both groups, a highly significant association was returned (p value 0.000). Therefore,
the present study inferred that the house officers had better tooth shade perceptibility, owing to their
clinical experience, than the dental students.
