Perception of changes in tooth color and position in dental students

Introduction: A perfect smile is a subjective impression and there are variations in the perception of a smile as aesthetically pleasing. The purpose of this study was to determine whether there is a difference in the perception of changes in the color and position of the front teeth among dental students with regard to gender, year of study, and experience of assisting in dental practice. Materials and methods: The research was conducted among students of the School of Dental Medicine in Zagreb using the Google Forms platform. Respondents evaluated the aesthetics of the smile on the initial unaltered photograph and on the other 21 photographs in which digital manipulation changed the color of one (tooth 11) or two teeth (11 and 21 or 13 and 23) and rotated tooth 12. Photographing was performed at standardized settings (ISO 100, SS 1/125, f2, WB 5500K, 10 MP) and lighting conditions. The color change was achieved by changing the white balance by 400 Kelvin (K) between each photograph. Typical and atypical rotations (10, 20 and 30 degrees) of tooth 12 were performed. Photographs were rated from 1 to 10. Results: The study involved 208 students (84.13% women and 15.87% men). The lowest grades were given to the photographs with the largest deviations in the brightness of tooth 11 and teeth 11 and 21. Senior students and students with experience in dental practice were significantly more critical in evaluating most photographs with discoloration and almost all rotations. Women were more critical in evaluating color. Conclusion: With a higher level of education and the experience gained by assisting, dental students sharpen their ability to detect color changes and the existence of irregularities and become more critical in assessing the aesthetics of a smile.
