Mouth breathing and atypical swallowing in adult orthodontic patients at Egas Moniz Dental Clinic: a pilot study

Communication abstract: Proceedings of the 5th International Congress of CiiEM - Reducing inequalities in Health and Society, held at Egas Moniz’ University Campus in Monte de Caparica, Almada, from June 16th to 18th, 2021.This is an open access article distributed under the Creative Commons Attribution License which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.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.info:eu-repo/semantics/publishedVersio

Is the orthodontic smile considered as aesthetic in adult patients?

Distributed under Creative Commons Licence CC-BY 4.0In 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.info:eu-repo/semantics/publishedVersio

X-ray vision: mental representation of adolescent’s oral cavity undergoing orthodontic treatment

Article licensed under a Creative Commons Attribution 4.0 International LicenseIntroduction: Oral Hygiene is notoriously relevant in the context of orthodontic treatment; however, oral health self-care is often considered inadequate.Objective: The objectives of this study focus on the perception of the inner oral cavity in patients and seek the enabling of Self-care through the empowerment of their knowledge.Materials and Methods: 25 subjects were asked to draw the interior of their oral cavity before (M1) and after (M2) going through orthodontic treatment. The percepts were then quoted using a content analysis grid of analytical categories and subcategories that was created especially for this study.Results and Conclusion: The results are suggesting that there are differences in the level of investment with a diminution in the representations of the inner oral cavity after the wear of orthodontic appliance. In addition to this, the initial directive was seemed to not be fully perceived by the subjects as most of the patients represented the inner oral cavity as an Extra-Oral configuration followed with a Frontal View Smile.info:eu-repo/semantics/publishedVersio

Ortodontia plástica - conceito e diferentes sistemas

A 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.info:eu-repo/semantics/publishedVersio

From the Orthodontic Smile to the Perfect Smile: A New Categorization

The 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

Validation of the Third Molar Maturation Index (I-3M) to assess the legal adult age in the Portuguese population

UIDB/04038/2020 UIDP/04038/2020Age estimation is a major step in forensic and legal procedures. Its relevance has been increasing due to growing society issues, such as identification of missing people, crimes against minors or lack of valid identification papers from locals or foreigners. Evaluation of the cut-off value of the Third Molar Maturation Index (I3M) = 0.08 for discriminating minors from adults in the Portuguese population. The left lower third molars were analysed by applying a specific cut-off value of 0.08 determined by Cameriere et al. in 2008. A sample of 778 digital panoramic radiographs of a representative Portuguese sample (442 females and 336 males), in the age range of 12–24 years (mean age 17.7 ± 2.98 years in females and 18.1 ± 3.0 years in males), was retrospectively evaluated. I3M decreased as the real age gradually increased in both sexes. The 0.08 cut-off score was valuable in discriminating adults from minors. According to the pooled results, the accuracy, by means of area under the curve, was 92.8% (95% confidence interval (CI) 91.0–94.6%). The proportion of correctly classified subjects (sensitivity) was 90.7% (95% CI 88.7–92.8%) and the specificity was 94.9% (95% CI 93.3–96.4%). The results show that I3M is a valuable method to differentiate minors from adults in the Portuguese population.publishersversionpublishe

Será o sorriso ortodôntico considerado estético em pacientes adultos?

Introdução: Foram efetuados estudos pioneiros nos últimos cinco anos, na Clínica Universitária Egas Moniz, sobre a representação mental da boca e do sorriso em pacientes adolescentes portadores de aparelho ortodôntico fixo. Nos referidos estudos, concluímos que, a partir da análise qualitativa dos resultados sobre a representação mental do sorriso, parece emergir uma nova forma de caracterizar o sorriso perfeito – O Sorriso Ortodôntico. Objetivos: Pretendemos com o presente estudo relevar a importância da autoperceção da boca e do sorriso, ao nível da representação mental de um sujeito adulto que recorre ao uso de aparelho ortodôntico fixo. O presente estudo de natureza qualitativa e exploratória tem como objetivo compreender, assim, a importância da autoperceção da boca e do sorriso ortodôntico em sujeitos adultos. Material e Métodos: A amostra do estudo é constituída por 80 sujeitos no estádio da adultícia (25-59anos) (OMS,2018), nomeadamente, sujeitos portadores de aparelho ortodôntico que foram convidados a efetuar dois desenhos do seu sorriso em dois momentos distintos: O primeiro desenho remete para o Momento antes do uso do aparelho ortodôntico (M1) e, no segundo desenho, o paciente é convidado a desenhar o seu sorriso após o uso do aparelho ortodôntico (M2). Resultados e Conclusões: Os resultados obtidos sugerem que, os principais motivos que levaram os pacientes a procurar cuidados dentários parecem estar mais conotados com problemas estéticos, nomeadamente, a busca por um sorriso alinhado e esteticamente harmonioso

Geographical Distribution of Periodontitis Risk and Prevalence in Portugal Using Multivariable Data Mining and Modeling

We aimed to estimate the geographical distribution of periodontitis prevalence and risk based on sociodemographic and economic data. This study used sociodemographic, economic, and health services data obtained from a regional survey and governmental open data sources. Information was gathered for all 308 Portuguese municipalities and compiled in a large set of 52 variables. We employed principal component analysis (PCA), factor analysis (FA) and clustering techniques to model the Portuguese nationwide geographical distribution of the disease. Estimation of periodontitis risk for each municipality was achieved by calculation of a normalized score, obtained as an adjusted linear combination of six independent factors that were extracted through PCA/FA. The municipalities were also classified according to a quartile-based risk grade in each cluster. Additionally, linear regression was used to estimate the periodontitis prevalence within the peri-urban municipality clusters, accounting for 30.5% of the Portuguese population. A total of nine municipality clusters were obtained with the following characteristics: mainly rural/low populated, including small villages (one), partly rural, including small cities (two), mainly urban/peri-urban, including medium-sized to large cities (4), and urban/large cities (2). Within the clusters, a higher periodontitis risk was identified for municipalities with lower income, older populations. The estimated periodontitis prevalence for the 18 municipalities included in the four peri-urban clusters ranged from 41.2% to 69.0%. Periodontitis prevalence estimates range from 41.2% to 69.0% for the municipalities characterized as peri-urban and mainly urban, most of them located in the Lisbon Metropolitan Area, the tenth largest in Europe
