Evaluation of the influence of the type of orthodontic bracket on the perception of age

Abstract

Background: The demand for orthodontic treatment has increased considerably among adult patients. Factors that contribute to this scenario are the use of new technologies, development of new materials and access to information. However, a large number of adults still do not adhere to treatment due to poor aesthetic appearance of brackets. Objective: To assess the influence of the use of metallic or aesthetic brackets on the perception of age. Methods: A 45-year-old female was photographed smiling and the image was manipulated in an editing program in order to generate a smile without brackets or with metallic or aesthetic brackets. A photographic album was assembled in addition to a questionnaire in which the interviewees answered questions about the age of the individual in the three situations. Results: The proportion of respondents who assigned age > 40 years (actual age) was higher in the group that evaluated the image without the orthodontic appliance. The frequency of respondents who indicated ages < 30 and between 30 and 40 years was higher in the groups that evaluated the images with aesthetic and metallic brackets, respectively. The appearance < 30 years of age was positively associated with the use of aesthetic and metallic brackets. The appearance of 30 to 40 years was positively associated with the use of metallic, but not with the use of aesthetic brackets. Conclusions: It was possible to infer that, according to the participants of this study, the use of orthodontic appliance made the individual look younger. There was no significant difference between aesthetic and metallic appliances in contributing to a more youthful appearance corresponding to age < 30 years. The appearance of 30 to 40 years of age was positively associated with the use of metallic brackets, but not with the use of aesthetic brackets.
