Perception of smile attractiveness among laypeople and orthodontists regarding the buccal corridor space, as it is defined by the eyes. An innovated technique.

OBJECTIVE: To investigate whether there is a relationship between the distance between the iris and pupil with the ideal size of buccal corridors. MATERIALS AND METHODS: A full-portrait image of a male Caucasian was used to create a set of 11 digitally modified images with different buccal corridor space. A web-based cross-sectional study was designed and distributed via an online survey to 200 laypeople and 200 orthodontists to assess image attractiveness, using a Visual analogue scale. For the statistical analysis, Wilcoxon signed-rank and Mann-Whitney U tests were used. The significance level was set at p < 0.05. RESULTS: The response rate for laypeople was 70% (n = 139), while the rate for orthodontists was 73% (n = 146). For the layperson group, the maximum smile attractiveness score was 10% of buccal width reduction, compared to the iris-pupillary distance, while for the orthodontists, it was 20%. The attractiveness of the smile was significantly reduced in both groups when the buccal corridor width was increased in comparison to the iris-pupillary distance. CONCLUSION: The length between the mesial part of the iris and the distal of the pupil, may constitutes a landmark for the estimation of the desired width of the buccal corridor. CLINICAL RELEVANCE: Inter iris-pupillary distance can be the starting point in the smile designing process, in order to perform a facial driven selection of buccal corridor size.

Na sua rotina clínica, voce prefere realizar ou não bisel em restaurações diretas de resina composta em dentes anteriores? / In your clinical practise, you orefere to realize or not bevel in direct direct restorations shrinkage in anterior teeth

Introdução - Em tempos de atitudes politicamente corretas, a Odontologia passou por grandes melhorias em seu perfil. A imagem do dentista é cada vez menos austera, tendemos a oferecer mais de um plano de tratamento ao paciente, escutamos mais a opinião do paciente e, sobretudo, tentamos não desgastar tecido dentário sadio ou desgastá-lo o mínimo possível. Assim, devemos questionar o uso de bisel em restaurações diretas anteriores.
