Aims: The aim of this study was to evaluate the visual esthetic perceptions of dentistry students and laypeople with regard to abrasions of the maxillary incisor edges in a frontal smile analysis. Materials and Methods: Abrasions were analyzed through a series of edited frontal photographs, at increments of 0.25, 0.5, 0.75, 1.0, and 1.5 mm, in two subjects (one male and one female, respectively). Raters were dentistry students and laypeople. To obtain ocular tracing data, two software programs Ogama and The Eye Tribe Tracker® were used together, which allowed us to visualize ocular movement in certain areas of interest. Specifically, the images were visualized by 30 dentistry students and 30 laypeople. Heat maps and scan paths were generated by the software programs to assess the main regions of ocular fixation. Results: According to the analyzed images, the larger the area of abrasion, the greater the visualization at that point. Small differences were observed in both groups; however, the students showed a higher concentration of attention in the region of abrasions as compared with the laypeople. Conclusions: There were differences between the groups. Dentistry students maintained their focus for most of the time in the region or near the region of abrasions, while laypeople largely diverged their gaze to other areas and allocated significant visual attention when they observed larger abrasions.
