- From the orthodontic smile to the new smile: a new categorizationPublication . Dias, Maria do Rosário; Alves, Valter Pedroso; Kizi, Gunel Mammadova; Delgado, Ana SintraThe facial symmetry from an esthetic standpoint is crucial. However, there are not much research that examine the malocclusion issue or the significance of the mouth and smile in the mental representation of the face. In this study, 151 kids and teenagers, both genders, aged 8 to 24, were asked to sketch two self-portraits of their mouths or smiles—before (and during) the usage of the orthodontic appliance. Participants seek therapy mostly for functional problems rather than cosmetic ones. The findings of this study provide insight into the significance of the mouth and smile for an individual’s sense of self and psychological well, where the maximization of the mental representation of the orthodontic smile emerges as a new categorization of the perfect smile.
- Is the orthodontic smile considered as aesthetic in adult patients?Publication . Mello, Gabriela; Evangelista, José Grillo; Alves, Valter Pedroso; Delgado, Ana Sintra; Dias, Maria do RosárioIn the last five years, pioneer studies were carried out in the Egas Moniz University Clinic surrounding the mental representation of the smile, centred on adolescent patients wearing orthodontic appliances, emerging with the results obtained as a new form of categorizing the perfect smile: The Orthodontic Smile. The present study is qualitative and exploratory and aims to understand the importance of the self-perception (mental representation) of the smile, now with the help of a new age range - Adult Patients. The sample consists of 100 subjects in the adult phase (25–59 y), namely patients wearing orthodontic appliances who were asked to draw two percepts about the self-perception of their own smile in two distinct moments: the first drawing, corresponding to before the wear of the orthodontic appliance (M1), and the second one, corresponding to drawing their smile after undergoing the orthodontic treatment (M2). The content analysis of the 200 drawings obtained was realized through a grid of content analysis, constituted by categories and subcategories. The patients also filled out a sociodemographic questionnaire, in which they responded to four open-ended questions in relation to the mental representation of the smile. Regarding the content analysis of the narrative, we highlight the fact that a Nice Smile seems to be mostly described as a Natural Smile and Aligned, being a motive for the seeking of dental treatment, primarily aesthetic issues, followed by functional considerations. When comparing the drawings before (M1) and after (M2) the wear of orthodontic appliances, the Category Broad Smile, is set up as the smile chosen as the most aesthetic. It seems that aesthetic motives represent the motivational power for the patient in the adult phase, when they decide to look for Orthodontic treatment.
- 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.
- Ortodontia plástica - conceito e diferentes sistemasPublication . Pereira, Dinis; Fernandes, Margarida; Gaudêncio, Filipa; Retto, Paulo Fernandes; Delgado, Ana SintraA necessidade de tratamento ortodôntico, na maioria dos pacientes, prende-se com a procura de alinhamento dentário ou de estética facial. A pouca popularidade dos aparelhos fixos tradicionais metálicos entre os pacientes deve-se ao reduzido sentido estético e receio de dor. Os aparelhos plásticos transparentes são uma boa alternativa (especialmente em jovens adultos com dentição permanente) para proceder ao tratamento ortodôntico, na medida em que não levantam tantas questões estéticas. Porém, há sistemas de ortodontia plástica que apresentam limitações e apenas tratam casos simples a nível anterior ou recidivas após tratamento ortodôntico. Existem assim vários sistemas que conseguem corrigir diversos tipos de maloclusões mais severas, mas o clínico tem que estar ciente sempre das limitações e decidir qual o sistema viável para proceder ao tratamento com ortodontia plástica.
- Prevalence and extent of chronic periodontitis and its risk factors in a Portuguese subpopulation: a retrospective cross-sectional study and analysis of clinical attachment lossPublication . Machado, Vanessa; Botelho, João; Amaral, António; Proença, Luís; Alves, Ricardo; Rua, João; Cavacas, Maria Alzira; Delgado, Ana Sintra; Mendes, José JoãoOBJECTIVES: To assess the prevalence and extent of chronic periodontitis, and its risk factors in a Portuguese subpopulation referred to periodontal examination. METHODS: This retrospective cross-sectional study used a subset of data from patients who sought dental treatment in a university dental clinic in the Lisbon metropolitan area. The sample consisted of 405 individuals (225 females/180 males), aged 20-90 years. All patients underwent a full-mouth periodontal examination and chronic periodontitis was defined as Clinical Attachment Loss (CAL) ≥ 3 mm affecting two or more teeth. Aggressive periodontitis cases were excluded from the analysis. RESULTS: Prevalence of chronic periodontitis was 83.5% (95% CI [80.4-86.6%]). For these subjects, CAL ≥ 3 mm affected 86.0% (95% CI [84.7-87.2]) of sites and 83.7% (95% CI [81.7-85.6]) of teeth, respectively. Mean CAL ranged from 3.6 to 4.3 mm, according to age. In the multivariate logistic regression model, smoking (OR = 3.55, 95% CI [1.80-7.02]) and older age (OR = 8.70, 95% CI [3.66-20.69] and OR = 4.85, 95% CI [2.57-9.16]), for 65+ and 45-64 years old, respectively, were identified as risk indicators for CAL ≥ 3 mm. CONCLUSIONS: This particular Portuguese adult subpopulation had a high prevalence of chronic periodontitis, with severe and generalized clinical attachment loss, and its presence was significantly associated with age and smoking. This data should serve to prepare future detailed epidemiological studies and appropriate public health programs.
