Abstract
(1) Background: orthodontic treatment can frequently be associated with discomfort and pain, a significant factor contributing to treatment discontinuation. (2) Methods: This study, conducted on 160 orthodontic patients across different age groups, aimed to explore the influence of age on patients' responses to treatment, particularly regarding changes in dietary patterns and weight loss. The patients were categorized into three age groups and assessed through a questionnaire about pain perception, pain latency, dietary changes, and weight loss associated with orthodontic appliances. (3) Results: Younger patients (6-12 years) reported lower pain levels, shorter pain latency and fewer alterations in dietary habits compared to adults (over 18 years). Females over 18 represented a significant portion of the sample, suggesting a self-driven inclination towards orthodontic treatment for aesthetic reasons. Fixed orthodontic appliances induced more significant pain than removable ones. Adults experienced more changes in dietary habits and weight loss than younger individuals. (4) Conclusions: the results provide valuable insights for orthodontic practitioners aiming to mitigate adverse effects and improve overall patient experience during treatment.
