Summary

This study aimed to evaluate the role of the mamelon effect on the perception of smile esthetics. A single portrait image was digitally modified by using the Photoshop CC (Adobe, USA) software program to create the mamelon effects at the incisal edge of maxillary incisors. Length (cervico-incisal) and value (level of gray color) were the variables in the modified images. There were two length (1mm and 3mm) and two value (low value, LV and high value, HV) modifications performed for the central incisors (2 teeth) and for the central and lateral incisors together (4 teeth). Eight full-face and 8 close-up images were created by cropping the modified images. In total 18 images (including the original ones) were evaluated by the participants. 135 participants (45 dentists, 45 specialists, and 45 laypeople) contributed to an online survey to evaluate the digitally modified images by using a visual analog scale ranging from 0 - 100, according to their level of attractiveness. The data were analyzed using Bonferroni Pairwise Comparisons. The results were presented as average±standard deviation. The deemed significance was set at \<.050.
