Each image was scored from one to ten.
Results: According to this study, no significant difference was observed between age, gender, and educational stage of participant (P>0.05). According to the groups judgments, the scores of images of pointed tip canine and round incisors and flat canine and round incisors were the highest and the images of pointed tip canine and square incisors and flat canine and square incisors were scored the least. Regarding the results of the Wilcoxon test, the pointed canine type was not effective in the esthetic judgment. The participants similarly rated the photos of pointed and flat canines (P>0.05).
