Evaluation of Shade Matching In Fixed Dental Prosthesis Using Usphs Guidelines

Abstract

Colour stability is one of the most important factors to achieve an esthetic smile.
Proper shade selection has to be done with respect to adjacent teeth. Human eye
perception is the most commonly used method for shade selection. Certain guidelines
to score the colour matching can help in improving the esthetics. Hence, this study
aims to check the prevalences of the scores of USPHS guidelines for colour matching
and check its correlation with the qualification of the dental students.This
retrospective study was carried out from the data obtained from the patients’ case
sheet. A total of 735 subjects were selected, undergoing treatment for fixed dental
prosthesis. The prevalence of three different scores was checked. Group 1- Score of
0, Group 2- Score of 1, Group 3-Score of 2, Group 4- Score of 3 and Group 5- Score
of 4.. The frequency of each score was checked and a Chi square test was done to
evaluate the association between the scores and qualification of the dental student. It
was observed that maximum students achieved a score of 1, followed by a score of
0, few people achieved a score of 2 and a handful of people achieved the scores of 3
and 4. Within the groups, it was seen that the prevalence of the score 0 was seen more
in postgraduate students as compared to the undergraduate students. It can be
concluded that the overall results achieved by the students were good. Further studies
need to be done to verify the results.
