Perceptions of Dentists and Non-Professionals on Some Dental Factors Affecting Smile Aesthetics: A Study from Vietnam

Abstract

Aim: It is important to meet the aesthetic expectation regarding the smile concept of both dentists and non-professionals after treatment is complete. Therefore, the study aims to evaluate the effects of altered displays in incisors, gingival margin, and other smile-related-factors on dentists’ vs. non-professionals’ aesthetics perceptions. Materials and method: We altered the features of 42 digital smile photographs to generate the changed displays in incisors, gingival margin, and other smile-related-factors. Then, these altered photographs were presented to 51 dentists and 51 non-professionals, and each picture was rated by each participant with a visual analog scale ranging from 0 (very ugly) to 100 (very beautiful). Results: We found that the alterations in incisors, gingival margin, and other factors affected studied groups’ aesthetic perception of smile. The ugly smile threshold rated by both groups for crown length of maxillary central incisors was 2.0 mm. This threshold was 2.5 mm for dentists, with moving the gingival margin of maxillary lateral incisors to the incisal ridge. The ugly thresholds for other smile-related-factors were different between studied groups; for example, the ugly thresholds for gingival exposure levels were 3 and 4mm for dentists and non-professionals, respectively. Thus, our data indicate that altered displays in incisors, gingival margin, and other smile-related-factors affected perceptions of both studied groups on smile aesthetics, but dentists tended to feel more refined than non-professionals. Dentists and non-professionals had significantly different aesthetic perceptions of the alteration of the gingival exposure level. Conclusion: Both dentists and non-professionals’ perceptions should be fully considered during orthodontic and prosthodontic treatment to achieve optimum aesthetic results.

Accuracy of Portable Face-Scanning Devices for Obtaining Three-Dimensional Face Models: A Systematic Review and Meta-Analysis

“…The use of a two-dimensional (2D) digital photograph is a basic approach to bring infographics into the realm of face assessment [ 1 , 4 , 9 ]. The desired measurements are visualized in 2D photos that are used to communicate between clinicians and patients.…”

Tratamento multidisciplinar para reabilitação estética anterior: relato de caso

“…Ao final do tratamento estético foi possível restabelecer a função e estética em uma abordagem de baixo custo que garantiu a satisfação da paciente. Além disso, as técnicas utilizadas devolveram a confiança da paciente com relação ao sorriso, impactando diretamente em sua qualidade de vida 3,4,6 .…”

“…Em vista disso, a odontologia tem avançado consideravelmente para atender aos anseios estéticos dos pacientes, e vem desenvolvendo tratamentos que, além de recuperar a função mastigatória, tem como objetivo restabelecer a harmonia do sorriso 1 . Assim, a inter-relação entre as especialidades odontológicas tornou-se básica e indispensável no planejamento e execução de tratamentos mais previsíveis e abrangentes garantindo ao paciente melhora da autoestima, qualidade de vida e bem-estar 2,4 .…”

Accuracy of three-dimensional optical devices for facial soft-tissue measurement in clinical practice of stomatology: A PRISMA systematic review

“…Two-dimensional (2D) measurement is a basic approach applied to analysis of maxillofacial morphological features by measuring the corresponding distance and angle on digital photographs taken from different angles. [ 2 , 3 , 7 ] However, this conventional method cannot accurately assess the complexity of 3D soft-tissue facial anatomy, for the reasons that it is relatively hard to appropriately evaluate the geodesic distance or volume of facial portions. [ 8 ] As a consequence, the prediction of results and prognosis of treatments can be limited in this method.…”
