Hirschfeld J, et al. - In this questionnaire-based cross-sectional pilot study, authors investigated the concern of participants affected by chronic periodontitis while undergoing orthodontic treatment as well as patient-related and tooth-related influence factors. They noted the interest of two-thirds of subjects in orthodontic therapy indicating the long-term healthy and esthetically appealing teeth as their principal goals. They found a significant relationship between subjectively felt impaired dental esthetics and an interest in orthodontic treatment. Significantly more interest of the older cases in orthodontic treatment was also reported.
