Oral health is particularly important in adolescents undergoing orthodontic treatment. However, studies have shown that, in this period, behaviors that are favorable toward oral health appear to decrease. Measures such as self-prevention and self-promotion do not seem to be as effective as they should be. This study has assessed dental hygiene habits and knowledge regarding oral health using a questionnaire that was given to the participants. The sample consisted of 200 subjects aged between 10 and 24 years old. The results suggest that there is a lack of knowledge surrounding oral-self-care and prove the need to invest in oral health education.

Background: Mouth breathing and atypical swallowing are myofunctional problems, emerging as a pathological adaptation. This exploratory study was aimed to investigate the possible relation between breathing and swallowing patterns in adults. Methods: A total of 58 patients referred to the Orthodontic Department at Egas Moniz Dental Clinic were enrolled. Results: Atypical swallowing was more prevalent in women (78.0%) than in men (47.1%). A significantly higher proportion of patients exhibiting both mouth breathing and atypical swallowing were identified (46.6%). Swallowing pattern was found to be significantly associated with gender and breathing pattern.
