Influence of orthodontic appliance design on employment hiring preferences.

The objective of this study was to evaluate the extent to which different types of orthodontic appliances influence the hiring process of an individual applying for a customer service position. A total of 7 images were created for 2 adult models: 1 male and 1 female. One image was produced without orthodontic appliances, and 6 simulated the use of orthodontic appliances, including a conventional metallic appliance with a gray elastic ligature, a conventional metallic appliance with blue elastic ligature, a conventional appliance with a transparent elastic ligature, a self-ligating metal appliance, a self-ligating esthetic appliance, and a clear aligner. A photo album was designed for each model and delivered, along with a questionnaire, to individuals in charge of job interviews and hiring. These evaluators included 236 individuals, divided into 4 groups according to age and gender: males between 18-35 years (M), males over 35 years (M > 35), females between 18-35 years (F), and females over 35 years (F > 35). The evaluators quantified the chance of hiring the models using a Visual Analogue Scale. The Mann-Whitney test was used to compare the evaluators according to gender and age. The Wilcoxon test was used to compare the models according to gender. The Kruskal-Wallis and Dunn post hoc tests were used to compare the appliances according to design. A 5% significance level was used for all tests. The clear aligner group showed the highest likelihood of being hired, followed by the group without orthodontic appliances, the groups with esthetic appliances (ie, conventional appliance with a transparent elastic ligature, and self-ligating esthetic appliance), and the groups with metallic appliances (ie, self-ligating metal appliance, conventional metallic appliance with gray elastic ligature, and conventional metallic appliance with blue elastic ligature). Assuming all other qualifications of the applicants are equivalent, the use of an orthodontic appliance may influence job interviews. The better the esthetics of the appliance, the higher the likelihood of the individual being hired.
