Evaluation of Isfahan dental practitioner's performance in relation to light and color rules to choose the color of teeth

Dentists’ awareness about the rules of light and color makes it possible to deliver restorations coordinated with the patient's tooth color. The aim of this study was to evaluate the performance of dentists in relation to the principles of light and color to select the color of teeth.
This descriptive/cross-sectional study was performed on a random sample of 200 dentists in Isfahan by using a questionnaire with 36 questions. The responses to the questions in the questionnaire were scored. The scores were analyzed statistically with Kolmogorov‒Smirnov and chi-squared tests (α=0.05).
The surrounding atmosphere color in most dental offices was bright. Dentists and assistants wore white uniforms in most cases. Most dentists used to select the teeth color under a light source, but increasing the number of light sources increased the success rate (p value Most dentists were in the moderate group in terms of following the rules of light and color selection. Although this is somewhat acceptable, color selection should be improved through continuous education programs.
