Dear Editor-in-Chief: The extrapolation of stress concept in the field of medicine is of great interest nowadays. In correlation with stress, anxiety often lies at the basis of the decisions to avoid an orthodontic treatment, delay the beginning of it or the scheduled visit to a consultation. The perception of the severity of a malocclusion varies according to the degree of physiognomic damage and according to the personal variables. Social anxiety, fear of being rejected by peers, conflicts with adults - parents, teachers - may occur both before and after applying the orthodontic appliance. The presence of a physical anomaly, especially when it affects patients’ facial appearance, has psychological and social consequences, being in most cases a major source of stress for patients and their family.
