Lay person’s perception of smile aesthetics in dental and facial views

Abstract

A lay panel perceived that the aesthetic impact of the visible anterior occlusion was greater in a dental view compared with a full facial view. The anterior visible occlusion, photographed subject, view type are factors, which influence the aesthetic perception of smiles. In addition, gender and level of education had an influence.

The influence of maxillary central incisor height-to-width ratio on perceived smile aesthetics

“…This reinforces that in the tooth wear set, the patients may not have noticed, or were not making their judgements based on the width-to-height ratio, because each of the different ratios were actually perceived as the most attractive by a number of patients. Although remaining very subjective because the ordering of attractiveness is people's opinions, these findings support previous studies 6,8,15,16 showing that dentists are more perceptive than patients to discrete changes in dental appearance. Clinically, dentists should be aware of this and be careful not to heavily impose their own strict criteria of what is aesthetic unless it is a patient concern.…”

“…These findings support those within dental literature, 6,8,15,16 showing dentists are more critical about dental appearance than patients. This study also shows that technicians found more of the images unattractive than patients.…”

Space closing versus space opening for bilateral missing upper laterals – aesthetic judgments of laypeople: a web-based survey

“…Reports in the literature about differences in gender judgments on dental or facial aesthetics are contradictory. Some studies have shown that females tend to be more critical (FloresMir et al, 2004, Kiekens et al, 2007, Kiekens et al, 2008, Zange et al, 2011, whereas other studies have found no significant difference between males and females (Johnston et al, 1999, Flores-Mir et al, 2004, Parekh et al, 2006, Bukhary et al, 2007, Martin et al, 2007, Rodrigues Cde et al, 2009, Meyer et al, 2014; however some of these studies have involved samples of just 20 lay participants.…”

The influence of varying maxillary incisal edge embrasure space and interproximal contact area dimensions on perceived smile aesthetics

“…Several studies have demonstrated that differences exist in the preferences of dental professionals and lay people 14,15,17 with regard to aspects of the smile aesthetics. Our fi ndings differ from these observations, in that only the perception of the 'most attractive' incisal edge embrasure space arrangement showed statistically signifi cant differences when comparing the study groups (p = 0.012).…”

“…Indeed, it has been suggested that non-dental professionals more readily discern differences in smile aesthetics when presented with images that show only the oral region. 14 Approaches involving close-up images, showing only the oral region, have also differed. Images showing only the arrangement of the teeth and gingivae without the surrounding lip curtain have been used [15][16][17] when assessing aspects of smile aesthetics, but in doing so, may alter the opinion of the assessor.…”
