Photographic analysis of smile in young adults from different regions of Ecuador
Abstract
The aim of this study was to determine whether there are differences in smile characteristics among young adults from different regions of Ecuador. To this end, frontal photographs of 93 participants, equally distributed among the three regions (Coast, Highlands, and Amazon), were taken, and the quantitative variables of the smile were analyzed using the AutoCAD software. The results revealed statistically significant differences (p < 0.05) between regions regarding the buccal corridor width and midline coincidence. Additionally, when considering sex as a variable, a significant difference was observed only in gingival display, which was greater in women. These findings suggest that geographical origin may influence smile characteristics, information that is particularly relevant and can be applied in various fields of dentistry, especially in orthodontics, where these features can be modified and improved through treatment.
