- Mouth breathing and atypical swallowing in adult orthodontic patients at Egas Moniz Dental Clinic: a pilot studyPublication . Barata, Ana Raquel; Kizi, Gunel; Proença, Luís; Alves, Valter; Delgado, Ana SintraBackground: 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.
- Orthodontic smile: a new categorization of the perfect smilePublication . Dias, Maria do Rosário; Ferreira, Ana; Pires, Maria Calejo; Alves, Valter; Delgado, AnaBackground and Aim: There is a shortage of empirical studies that combine the problem of malocclusion to the importance of the self-perception of the mouth/smile in the mental representation of the self-image of the face, which is the aim of the present qualitative and exploratory study. Subjects and Methods: The convenience sample consisted of 151 children and youngsters of both genders, aged 8–24 years, who used an orthodontic appliance for 6 months to 1 year, and were invited to draw two portraits of their mouth/smile before (M1) and after (M2) the use of an orthodontic appliance. Results: The main reasons that underpin the use of an orthodontic appliance are defined by the crooked teeth correction, malocclusion correction, and interdental spaces categories, in which having the perfect smile was only relevant to preteens. Discussion and Conclusions: In the present study, we have identified the orthodontic smile as a new categorization of a perfect smile associated with the social display of a look with perfect teeth.
- The anthropomorphized emotional profile of a (un) healthy toothPublication . Dias, Maria do Rosário; Ahmad, Samir; Santos, Helcínia Dias dos; Pires, Maria Calejo; Ferreira, Ana; Alves, Valter; Delgado, AnaDrawing as a projective technique allows the access to the child's intrapsychic experiences. Notoriously, the use of drawings has been known as a referential research instrument in qualitative Health studies. Objectives: This exploratory study aims at understanding the mental representation of the concept of a healthy tooth and of an unhealthy tooth, through anthropomorphized drawings made by children, aged 6-12 years. Methods: The sample consisted of 150 children of both genders who attended at least one dental appointment at a University Dental Clinic of a metropolitan urban area. Drawings that showed anthropomorphized teeth (n = 300) were selected to perform the content analysis of the anthropomorphized features. Results: There is a clear variation in the level of anthropomorphizing of teeth according to age and gender. Conclusion: The results point to an increase in subject’s mental representation of reality in drawings in accordance to subject’s age, most significantly from 10 years onwards.
