“…Therefore, numerous clinical and experimental studies have attempted to define how an esthetically pleasing smile can be achieved after orthodontic treatment. As a result, buccal corridors, 2-5 smile arc, 6,7 incisor protrusion, 1,8 and gingival display 1,9 have commonly been cited as the potential characteristics that influence the esthetic outcome of an orthodontically treated patient. Our current knowledge suggests that alterations in these variables directly affect a person's esthetic perception.…”

Objective: To investigate the common denominators of an esthetically pleasing smile in patients who were considered to be successfully treated upon the submission to American Board Orthodontics (ABO) clinical examination. Material and Methods: A total of 462 patients were examined. Ninety subjects that fulfilled the inclusion criteria were included. Standardized digital smile photographs of the subjects were rated by 30 panel members, including orthodontists, general dentists, and parents of orthodontic patients, using a numeric version of the visual analog scale. Three groups were formed using the mean esthetic score 6 standard deviation range: unattractive (n 5 21), average (n 5 47), and attractive (n 5 22) smiles. Eleven smile characteristics were digitally measured on the photographs and compared between the groups using one-way analysis of variance and x 2 tests. Additionally, regression analyses were used to investigate the association of the smile characteristics with the esthetic score. Results: A significant difference was found between the three groups for the comparison of smile arc relationship (P , .001). When all the variables used in this study were entered in the regression analysis, a positive association was found (r 5 0.658; r 2 5 0.434; P , .001). Additionally, two models were defined using stepwise regression. The first model included the smile arc (r 5 0.478; r 2 5 0.228; P , .001), and the second model had both the smile arc and right gingival display/ visible dentition display ratio (r 5 0.567; r 2 5 0.321; P , .001). Conclusions: A harmonious smile arc relationship and less gingival display during a smile are significantly associated with smile attractiveness in patients considered successfully treated according to ABO standards.

“…Osmijeh je važan u ekspresiji lica, on utječe na čovjeko-vu percepciju privlačnosti i temelj je socijalne interakcije (1). Dentalna estetika uvijek je bila predmet rasprave jer, kako znamo, ljepota je u očima promatrača i može varirati od osobe do osobe, ovisno o njezinu iskustvu i socijalno-ekonomskom položaju te obrazovanju (2,3).…”

“…In addition to the shape and size of the upper anterior teeth, the relationship between the teeth and dental arch has a very important role in dental esthetics, wherein its most important aspect is the ratio of incisors and canines (1). This relationship is based on the theory of golden proportions (the golden section) and dynamic symmetry (6).…”

“…In general, laypersons are more forgiving than are dental professionals in the evaluations of dental esthetics. 15 In our previous study 16 investigating the attractive amounts of buccal corridor, both orthodontists and orthodontic patients showed similar tendencies in their preferences. To date, there has been no report that has compared preferences for vermilion height between orthodontists and orthodontic patients.…”

To evaluate the influence of vermilion height on the assessment of lip attractiveness by Japanese and Korean orthodontists and orthodontic patients. Materials and Methods: Vermilion heights were modified by increasing or decreasing the vermilion height in 1.0-mm increments from 23.0 mm to 3.0 mm with reference to an average vermilion height. Participants ranged from 15 to 29 years of age and comprised 29 Japanese and 25 Korean orthodontists and 96 Japanese and 72 Korean orthodontic patients. They all rated the attractiveness of seven images with altered vermilion height using a visual analog scale. Results: Across the participant groups, there were significant differences in the median esthetic scores for the seven vermilion height levels tested. The Japanese and Korean raters assigned the highest scores to the average vermilion height and assigned the lowest scores to the +3-mm increased vermilion height. The ranges of vermilion height preferred by orthodontists were found to be within the ranges preferred by orthodontic patients when evaluating the preferences in lip esthetics by country. Conclusions: We conclude that the 21-mm to +1-mm range for the average vermilion height is considered attractive for lips for both Japanese and Korean people. (Angle Orthod. 2014;84:239-245.)
