Mandibular advancement device in obstructive sleep apnea treatment: what happens to the condyle position and patient response?

BACKGROUND: This study aims primarily to assess the mandibular condyles and patient response to MAD therapy using cone-beam computed tomography (CBCT). Also, the study proposes to analyze whether variations in condylar position, OSA severity and mandibular protrusion influence patient response. METHODS: 23 patients diagnosed with mild/moderate OSA and treated with MAD comprised the sample. Clinical, CBCT, and PSG assessments were conducted at baseline and with MAD in therapeutic protrusion (4-6 months of MAD use). The condyle position was vertically and horizontally evaluated at baseline and at the therapeutic protrusion. RESULTS: The condyle position significantly changed with MAD, showing anterior (7.3 ± 2.8 mm; p < 0.001) and inferior (3.5 ± 1 mm; p < 0.001) displacement. Patients with mild OSA required more protrusion (p = 0.02) for improvement. Responders exhibited a significantly prominent (p = 0.04) anterior baseline condyle position. A negative modest correlation was found between treatment response and baseline condyle anterior position (p = 0.03; r=-0.4), as well as between OSA severity and the percentage of maximum protrusion needed for therapeutic protrusion (p = 0.02; r=-0.4). The patient protrusion amount did not predict condylar positional changes. Neither condyle position, OSA severity, nor therapeutic protrusion were predictors of MAD treatment response. CONCLUSION: MAD resulted in anterior and inferior condylar displacement, and the amount of protrusion did not predict condylar positional changes. Responders showed a more anterior baseline condyle position. OSA severity and mandibular protrusion did not predict treatment response.

Anthropometric measures and obstructive sleep apnea in children and adolescents: a systematic review of the literature and meta-analysis.

BACKGROUND: Anthropometric measurements can be used to identify children at risk of developing obstructive sleep apnea (OSA). The study aimed to assess which anthropometric measurements (AMs) are most associated with an increased predisposition to develop OSA in healthy children and adolescents. METHODS: We performed a systematic review (PROSPERO #CRD42022310572) that searched eight databases and gray literature. RESULTS: In eight studies with low-to-high risk of bias, investigators reported the following AMs: body mass index (BMI), neck circumference, hip circumference, waist-to-hip ratio, neck-to-waist ratio, waist circumference, waist-to-height ratio, and facial AMs. The meta-analysis showed that the OSA group had an average of 1.00 cm greater for the neck circumference (p < 0.001; Cohen's d = 2.26 [0.72, 5.23]), 3.07 cm greater for the waist circumference (p = 0.030; Cohen's d = 0.28 [0.02, 0.53]), 3.96 cm greater for the hip circumference (p = 0.040; Cohen's d = 0.28 [0.02, 0.55]), 5.21° greater for the cervicomental angle (p = 0.020; Cohen's d = 0.31 [0.03, 0.59]), and 1.23° greater for maxillary-mandibular relationship angle (p < 0.001; Cohen's d = 0.47 [0.22, 0.72]) than the control group. The mandibular depth angle had a reduction of 1.86° (p = 0.001; Cohen's d = -0.36° [-0.65, -0.08]) in control than in patients with OSA. The BMI (p = 0.180), waist-to-hip ratio (p = 0.280), neck-to-waist ratio (p = 0.070), maxillary depth angle (p = 0.250), and upper/lower face height ratio (p = 0.070) showed no significant differences between groups. CONCLUSIONS: Compared to the control group, the OSA group exhibited a greater mean difference in neck circumference, the only anthropometric measurement with high certainty of evidence.

3D analysis of maxillomandibular morphology in hyperdivergent and hypodivergent individuals: A cross-sectional study.

INTRODUCTION: The aim of this cross-sectional study was to investigate maxillomandibular morphology in hyperdivergent and hypodivergent individuals, using 3D surface models generated by cone-beam computed tomography (CBCT). METHODS: The sample consisted of 60 CBCTs (30 males, 30 females) patients aged 12-30 years, divided into two groups comprising hyperdivergent (≥35°) and hypodivergent (≤30°) individuals, according to the mandibular plane (MP) angle. Multiplanar reconstructions were used to mark the landmarks, and 3D surface models were created to evaluate structures of the maxillomandibular complex, including condyle, ramus, symphysis and palatal height. Intergroup comparisons were performed by independent t-test. Pearson's correlation test was used (P < .05) to evaluate the correlation of the MP angle with the angles and linear measurements of other structures. RESULTS: Significant differences were found between the groups regarding condylar width, ramus height, condylar plus ramus height, mandibular length, gonial angle, palatal plane angle and palatal-mandibular angle. No differences (P > .05) were found for the condylar height, symphysis inclination angle or palatal height. Correlations (P < .05) were found between the MP angle and structures of the maxillomandibular complex. CONCLUSIONS: Hyperdivergent (MP ≥ 35°) and hypodivergent (MP ≤ 30°) individuals present different skeletal morphology regarding condylar width, ramus height, condylar plus ramus height, mandibular length, gonial angle, palatal plane angle and palatal-mandibular angle. There is a significant correlation between MP angle and morphological structures such as condyle, ramus, symphysis, palatal plane angle and palatal-mandibular angle.

Thermal Contaminants in Coffee Induced by Roasting: A Review.

Roasting is responsible for imparting the main characteristics to coffee, but the high temperatures used in the process can lead to the formation of several potentially toxic substances. Among them, polycyclic aromatic hydrocarbons, acrylamide, furan and its derivative compounds, α-dicarbonyls and advanced glycation end products, 4-methylimidazole, and chloropropanols stand out. The objective of this review is to present a current and comprehensive overview of the chemical contaminants formed during coffee roasting, including a discussion of mitigation strategies reported in the literature to decrease the concentration of these toxicants. Although the formation of the contaminants occurs during the roasting step, knowledge of the coffee production chain as a whole is important to understand the main variables that will impact their concentrations in the different coffee products. The precursors and routes of formation are generally different for each contaminant, and the formed concentrations can be quite high for some substances. In addition, the study highlights several mitigation strategies related to decreasing the concentration of precursors, modifying process conditions and eliminating/degrading the formed contaminant. Many of these strategies show promising results, but there are still challenges to be overcome, since little information is available about advantages and disadvantages in relation to aspects such as costs, potential for application on an industrial scale and impacts on sensory properties.

Metabolomic Profile of Volatile Organic Compounds from Leaves of Cashew Clones by HS-SPME/GC-MS for the Identification of Candidates for Anthracnose Resistance Markers.

Anthracnose caused by Colletotrichum gloeosporioides affects the leaves, inflorescences, nuts, and peduncles of cashew trees (Anacardium occidentale). The use of genetically improved plants and the insertion of dwarf cashew clones that are more resistant to phytopathogens are strategies to minimize the impact of anthracnose on cashew production. However, resistance mechanisms related to the biosynthesis of secondary metabolites remain unknown. Thus, this study promoted the investigation of the profile of volatile organic compounds of resistant cashew clone leaves ('CCP 76', 'BRS 226' and 'BRS 189') and susceptible ('BRS 265') to C. gloeosporioides, in the periods of non-infection and infection of the pathogen in the field (July-December 2019 - Brazil). Seventy-eight compounds were provisionally identified. Chemometric analyses, such as Principal Component Analysis (PCA), Discriminating Partial Least Squares Analysis (PLS-DA), Discriminating Analysis of Orthogonal Partial Least Squares (OPLS-DA), and Hierarchical Cluster Analysis (HCA), separated the samples into different groups, highlighting hexanal, (E)-hex-2-enal, (Z)-hex-2-en-1-ol, (E)-hex-3-en-1-ol, in addition to α-pinene, α-terpinene, γ-terpinene, ß-pinene, and δ-3-carene, in the samples of the resistant clones in comparison to the susceptible clone. According to the literature, these metabolites have antimicrobial activity and are therefore chemical marker candidates for resistance to C. gloeosporioides in cashew trees.

Enhancement of chlorhexidine activity against planktonic and biofilm forms of oral streptococci by two Croton spp. essential oils from the Caatinga biome.

This work investigates the ability of two Croton spp. essential oils (EO) to enhance chlorhexidine (CHX) activity against oral streptococci. EO's chemical composition of Croton argyrophyllus and C. pluriglandulosus was determined by GC-MS/FID. The microbial growth kinetics and minimum inhibitory concentration (MIC) of EOs and CHX were determined, followed by their synergism against S. mutans UA159 and ATCC 25175, S. salivarius ATCC 7073 and S. sp. ATCC 15300. The microplate-based method was used to determine the EO/CHX activity against 24-h-old biofilms. The major compounds were α-pinene (54.74%) and bicyclogermacrene (16.08%) for EOAr and 1,8-cineole (17.41%), methyleugenol (16.06%) and elemicin (15.99%) for EOPg. Both EO had MIC around 16,000 µg/mL. EOs/CHX presented a synergistic effect against most strains (FICi from 0.133 to 0.375), and OE/CHX-treated biofilms showed a reduction in biomass and cell viability compared to CHX, only (p < 0.01). Thus, the EOs works as natural adjuvants for CHX.

Methodological parameters for upper airway assessment by cone-beam computed tomography in adults with obstructive sleep apnea: a systematic review of the literature and meta-analysis.

BACKGROUND: A reliable method for analyzing the upper airway (UA) remains a challenge. This study aimed to report the methods for UA assessment using cone-beam computed tomography (CBCT) in adults with obstructive sleep apnea (OSA). METHODS: We performed a systematic review (PROSPERO #CRD42021237490 and PRISMA checklist) that applied a search strategy to seven databases and grey literature. RESULTS: In 29 studies with moderate-to-high risk of bias, investigators mostly reported the body position during CBCT (upright or supine) and hard tissue references, diverging in UA delimitation and terminologies. The meta-analysis showed two subgroups (upright and supine), and no statistical differences were identified (p = 0.18) considering the UA area. The volume in the OSA group was smaller than that in the control group (p < 0.003 and Cohen's d = - 0.81) in the upright position. Patients with OSA showed smaller anteroposterior dimensions than the control group and were not affected by the position during image acquisition (p = 0.02; Cohen's d = - 0.52). The lateral measurements were also lower in the OSA group (supine) (p = 0.002; Cohen's d = - 0.6). CONCLUSIONS: Patients with OSA showed smaller UA measurements in the upright (volume) and supine (lateral dimension) positions. The anteroposterior dimension was also reduced in patients with OSA compared to the control group, regardless of the position during CBCT acquisition.

Temporomandibular joint articular disc position and shape in skeletal Class III.

OBJECTIVE: To compare the position and shape of the temporomandibular joint (TMJ) articular disc among the sagittal and vertical skeletal patterns in Angle Class III, Class III subdivision malocclusion and normal occlusion. The null hypothesis was that there was no difference in disc position and shape in different (1) malocclusions and (2) skeletal patterns. METHODS: This cross-sectional observational study evaluated 105 patients divided into 3 groups: Class III (33, 9.39 ± 1.96 years), Class III subdivision (45, 9.51 ± 1.59 years) and a normal occlusion (27, 10.24 ± 0.87 years) was included as healthy control. Severity of the maxilla-mandibular anteroposterior discrepancy and vertical facial pattern were determined using 2D cephalometry, and the position and shape of the articular discs were evaluated in magnetic resonance images. Statistical parametric and non-parametric tests and Kappa analysis for intra-observer and inter-observer assessment were used (p ≤ .05). RESULTS: Significant between-group differences were found in articular disc position. In the normal occlusion group, all the articular discs were well positioned. In Class III and Class III subdivision, the discs were displaced in 30.3% and 12.2% of the TMJs, respectively. Sagittal and vertical skeletal patterns did not affect the findings significantly. The Class III subdivision malocclusion group is probably different from the other groups, showing 97.7% of biconcave discs in both TMJs. CONCLUSION: The longitudinal follow-up of this sample becomes relevant as the two groups with malocclusion in the pre-peak phase of pubertal growth showed differences in the prevalence of displacement and form of the articular disc, with no association with their vertical facial characteristics.

Assistência às pessoas com transtornos mentais em conflito com a lei: perspectiva de gestores e profissionais de saúde Abstract / Care for people with mental disorders in conflict with the law: the perspective of health managers and professionals

Resumo O estudo teve como objetivo analisar a assistência às pessoas com transtornos mentais em conflito com a lei na perspectiva de gestores e profissionais de saúde. Trata-se de um estudo de caso, de abordagem qualitativa, realizado em janeiro de 2020, com 10 profissionais que atuavam no Hospital de Custódia e Tratamento Psiquiátrico do Estado do Rio Grande do Norte. Para coleta de dados, utilizou-se um questionário sociodemográfico e entrevista semiestruturada. O conteúdo textual decorrente das entrevistas foi submetido à análise textual lexicográfica, com auxílio do software IRAMUTEQ, e a análise dos dados foi realizada a partir de literatura pertinente. Emergiram três categorias: As mudanças nas relações de trabalho e o impacto na assistência; A organização da Rede de Cuidado; e A assistência intramuros e os entraves para desinstitucionalização. Conclui-se que a assistência às pessoas com transtornos mentais em conflito com a lei é influenciada pelas relações de trabalho; tem dificuldades relacionadas à estrutura física e à dinâmica das instituições; enfrenta entraves para garantir a desinstitucionalização, ao passo que fragmenta os vínculos e não implementa o Projeto Terapêutico Singular. Todavia, esforços têm sido empreendidos para articular a rede de cuidado de base territorial.

Abstract The study aimed to analyze the care of people with mental disorders in conflict with the law from the perspective of managers and health professionals. This is a qualitative case study conducted in January 2020 with 10 professionals working at the Psychiatric Custody and Treatment Hospital of the State of Rio Grande do Norte, Brazil. For data collection, a sociodemographic questionnaire and semi-structured interview were used. The textual content resulting from the interviews was submitted to lexicographic textual analysis, with the help of the IRAMUTEQ software and data analysis was performed based on pertinent literature. Three categories emerged: Changes in work relationships and impact on care; The organization of the Care Network; and Intra-wall care and barriers to deinstitutionalisation. It is concluded that the care for people with mental disorders in conflict with the law is influenced by work relationships; has difficulties related to the physical structure and dynamics of institutions; it faces obstacles to ensure deinstitutionalization while fragmenting ties and not implementing the Singular Therapeutic Project. However, efforts have been made to articulate the territorial-based care network.

Dispensação de medicamentos no sistema prisional: garantia de assistência farmacêutica? / Medicine dispensation in the prison system: Is pharmaceutical care assured?

Resumo Este artigo objetiva analisar o processo de dispensação de medicamentos em unidades prisionais. Foi realizado um estudo qualitativo, em sete penitenciárias do estado da Paraíba, sendo entrevistados 13 profissionais de saúde e 43 pessoas privadas de liberdade em uso de medicamentos essenciais/estratégicos, no período compreendido entre os meses de fevereiro a agosto de 2016. Os resultados foram categorizados na perspectiva da análise de conteúdo de Bardin e três categorias emergiram: armazenamento de medicamentos no sistema penitenciário, processo de dispensação de medicamentos no sistema penitenciário e responsabilidades sanitárias para garantir a assistência farmacêutica. Conclui-se que a inexistência de farmácias, o não cumprimento legal no que se refere a presença do profissional com habilidade e competência técnica para realizar a dispensação primando pelos padrões de qualidade/segurança e pela relevância das orientações relacionadas ao uso e armazenamento, associado a falta de clareza na definição das responsabilidades sanitárias dos gestores a partir da instância de governo, são fatores que comprometem a política uma vez que incrementam o investimento, mas não garantem a assistência farmacêutica no sistema prisional.

Abstract This paper aims to analyze the process of medicine dispensation in prisons. A qualitative study was conducted in seven penitentiaries in Paraíba with 13 health professionals and 43 people deprived of liberty using essential/strategic medicines from February to August 2016. The results were categorized from the perspective of Bardin's content analysis. Three categories emerged: medicine storage location in the prison system, delivery process in the prison system, and health-related responsibilities with pharmaceutical care. We can conclude that the lack of pharmacies, the legal non-compliance regarding the availability of skilled professionals with technical competencies to perform the dispensation, focusing on the quality/safety standards and relevance of the use and storage guidelines associated with the lack of clarity in the definition of health responsibilities of managers from a government authority, are factors that compromise the policy since they increase the investment, but do not ensure pharmaceutical care in the prison system.

Food Composition Data and Tools Online and Their Use in Research and Policy: EuroFIR AISBL Contribution in 2022.

Food, nutrition, and health are linked, and detailed knowledge of nutrient compositions and bioactive characteristics is needed to understand these relationships. Additionally, increasingly these data are required by database systems and applications. This communication aims to describe the contribution to databases and nutrition fields as well as the activities of EuroFIR AISBL; this member-based, non-profit association was founded to ensure sustained advocacy for food information in Europe and facilitate improved data quality, storage, and access as well as encouraging wider exploitation of food composition data for both research and commercial purposes. In addition to the description of its role and main objectives, a snapshot of EuroFIR AISBL's activities over the years is also given using a quantitative research literature analysis approach. The focus of this communication is to provide descriptions and updates of EuroFIR's online tools, i.e., FoodEXplorer, eBASIS, and PlantLIBRA, by highlighting the main uses and applications. Integrating food-related infrastructures and databases, following standardized and harmonized approaches, and considering interoperability and metrological principles are significant challenges. Ongoing activities and future plans of EuroFIR AISBL are highlighted, including, for instance, work within the Food Nutrition Security Cloud (FNS-Cloud) to make food, nutrition, and (food) security data more findable, accessible, interoperable, and ultimately reusable.

Care of People with Post-COVID-19 Sequelae in the Scope of Primary Health Care: Scoping Review Protocol.

The sequelae of COVID-19 disease significantly impact the quality of life of people, requiring long-term longitudinal care for recovery and rehabilitation. Primary health care is fundamental in the reception, monitoring, and multi-professional follow-up of post-COVID-19 symptoms and complications. This study proposes a scoping review protocol to identify and map the care process of monitoring and multi-professional follow-up of post-COVID-19 sequelae within the scope of primary health care worldwide. This protocol was based on the Joanna Briggs Institute Manual and guided by PRISMA-ScR. Articles, theses, dissertations, and official documents searched in several databases (MEDLINE/PubMed, Scopus, LILACS, Web of Science, Embase, and gray literature) will be included. Two independent reviewers will organize and select studies according to inclusion and exclusion criteria using the Rayyan software. The selected publications will be organized and summarized using a checklist proposed by the PRISMA-ScR. Simple descriptive statistics will analyze the quantitative data, while thematic analysis will be used for the qualitative data. The final scoping review will present the main findings, challenges, limitations, and potential research gaps related to the care of people with post-COVID-19 sequelae.

Accuracy of artificial intelligence for tooth extraction decision-making in orthodontics: a systematic review and meta-analysis.

OBJECTIVE: This study aimed to analyze the accuracy of artificial intelligence (AI) for orthodontic tooth extraction decision-making. MATERIALS AND METHODS: PubMed/MEDLINE, EMBASE, LILACS, Web of Science, Scopus, LIVIVO, Computers & Applied Science, ACM Digital Library, Compendex, and gray literature (OpenGrey, ProQuest, and Google Scholar) were electronically searched. Three independent reviewers selected the studies and extracted and analyzed the data. Risk of bias, methodological quality, and certainty of evidence were assessed by QUADAS-2, checklist for AI research, and GRADE, respectively. RESULTS: The search identified 1810 studies. After 2 phases of selection, six studies were included, showing an unclear risk of bias of patient selection. Two studies showed a high risk of bias in the index test, while two others presented an unclear risk of bias in the diagnostic test. Data were pooled in a random model and yielded an accuracy value of 0.87 (95% CI = 0.75-0.96) for all studies, 0.89 (95% CI = 0.70-1.00) for multilayer perceptron, and 0.88 (95% CI = 0.73-0.98) for back propagation models. Sensitivity, specificity, and area under the curve of the multilayer perceptron model yielded 0.84 (95% CI = 0.58-1.00), 0.89 (95% CI = 0.74-0.98), and 0.92 (95% CI = 0.72-1.00) scores, respectively. Sagittal discrepancy, upper crowding, and protrusion showed the highest ranks weighted in the models. CONCLUSIONS: Orthodontic tooth extraction decision-making using AI presented promising accuracy but should be considered with caution due to the very low certainty of evidence. CLINICAL RELEVANCE: AI models for tooth extraction decision in orthodontics cannot yet be considered a substitute for a final human decision.

Balance between maternal antiviral response and placental transfer of protection in gestational SARS-CoV-2 infection

Maternal immune responses during pregnancy protect the growing fetus by clearing infection, preventing its vertical transmission, and through transplacental transfer of protective immune mediators to the fetus. How maternal immune response balances SARS-CoV-2 antiviral responses with transplacental transfer of protection to the fetus remains unclear. Our study shows that upon SARS-CoV-2 maternal infection, neutralizing antibodies (NAbs) are infrequently detected in cord blood. We uncovered that this is due to impaired IgG-NAbs placental transfer in symptomatic infection and to the predominance of maternal SARS-CoV-2 NAbs of the IgA and IgM isotypes, which are prevented from crossing the placenta. Crucially, the decision between favoring maternal antiviral response or transplacental transfer of immune protection to the fetus appears to hinge on the balance between IL-6 and IL-10 induced by SARS-CoV-2 infection, decreasing or increasing transplacental transfer of IgG-NAbs, respectively. In addition, IL-10 inversely correlates with maternal NK cell frequency. Finally, we found that ongoing infection favored perinatal transfer of maternal NK cells, highlighting a maternal sponsored mechanism to protect the newborn from horizontal transmission of infection. Our data point to an evolutionary trade-off which at once optimizes maternal viral clearance and vertical transfer of immune protection during the more susceptible perinatal period. Brief SummaryIn SARS-CoV-2 maternal infection, the balance between maternal antiviral response and transplacental transfer of cellular and humoral (NAb) protection hinges on maternal IL-6 and IL-10.

Environmental and Seasonal Effects on Gerridae Assemblages (Heteroptera: Gerromorpha) from a Stream in Brazilian Savannah.

Our aim here was to assess the seasonal (dry, ebb, and rainy seasons), spatial (upstream, intermediate, and downstream), and environmental effects on the dynamics of Gerridae assemblages (Heteroptera: Gerromorpha) in a Cerrado stream, in central-western Brazil. We sampled the insects on the water line between May 2011 and April 2014 with an 18 cm diameter sieve. We used the scanning method in 100 m of stream in each sampled locality. We sampled 3690 individuals of 19 species. There was a seasonal difference in abundance, which was a result of a lower abundance in the rainy season, but this did not differ between different environments. The estimated species richness was lower upstream and in the rainy season. Species composition was different between the upstream and downstream portions. It was also different among all seasons, with the greatest difference occurring between the rainy and dry seasons. The abiotic factors were responsible for structuring the assemblages in different seasons. The observed differences among seasons in abundance, richness, and species composition have implications for conservation since changes in the structure of the vegetation in the stream edges change the hydrological cycle of streams, and consequently the diversity of the Gerridae assemblages. There was variation in richness and composition between such small distances (upstream and downstream). This shows how sensitive this system can be, and how important elements of the stream's trophic, with the Gerromorpha, can be easily altered.

"A vida como ela é" e o desenvolvimento de competências e autonomia na integração ensino-serviço-comunidade / "Life as it is" and the development of skills and autonomy in the teaching-service-community integration

A formação em Odontologia alinhada às demandas atuais de saúde tem sido uma agenda importante. O objetivo desta pesquisa foi compreender os aprendizados a partir dos estágios supervisionados na perspectiva do desenvolvimento de competências e autonomia, a partir da voz de estudantes de Odontologia. Utilizou-se pesquisa qualitativa, com dois gruposfocais, com 13 estudantes, de ambos os sexos,de um curso de Odontologia, de uma instituição federal de ensino noNordeste do Brasil. Procedeu-se à análise temática de conteúdo. Os Estágios Supervisionados da Saúde Coletiva atuam como oportunidades de ensino-aprendizagemavaliação, permitindo vivência nos serviços públicos de saúdelocais e territórios, sensibilizando o estudante para o cuidado integral e para a compreensão ampliada do processo saúde-doença. As vivências partemsempre da premissa de que o aprendizado está vinculado aos serviços de saúde e a um percurso construído coletivamente por todos. Portanto, a compreensão dos estudantes sobre a integração entre o ensino, o serviço e a comunidade, permitiram a articulação entre a teoria e a prática da Saúde Coletiva e o desenvolvimento de competências "socio-lógicas" implicadas aos contextos do trabalho em saúde. Com esse entendimento, os participantes reconheceram o princípio da educação pelo/com o trabalho e a importância de todos para troca e produção de conhecimentos e de saberes em saúde (AU).

Dentistry education aligned with current health demands has been an important topic on the agenda. The objective of this research was to understand the acquired knowledge in supervised internships in terms of the development of skills and autonomy, from the point of view of dentistry students. Qualitative research was used, with two focus groups, with 13 students of both genders, from a dentistry course, from a Federal Educational Institution in Northeastern Brazil. A thematic content analysis was performed. The Collective Health Supervised Internships act as teaching-learning evaluation opportunities, allowing experience in local public health services and territories, creating student awareness of comprehensive care and a broader understanding of the health-disease process. The experiences are always based on the premise that learning is linked to health services and to a path built collectively by everyone. Therefore, the students' understanding of the integration between teaching, service and community allowed the articulation between theory and practice of Collective Health and the development of "socio-logical" competencies involved in the contexts of work in healthcare. With this understanding, the participants recognized the principle of education through/with work and the importance of everyone to exchange and produce knowledge and health education (AU).

Trata-se de um estudo observacional e transversal, com metodologia exploratória, descritiva e de avaliação. A abordagem utilizada foi quantitativa, por meio da aplicação de questionário online, por meio de instrumento com critérios validados. A amostra de professores e estudantes do curso foi censitária. A Integração ensino-serviço obteve o melhor desempenho relativo entre as dimensões avaliadas tanto por estudantes quanto por professores. A maior parte dos estudantes considerou o curso adequado às DCN (50,2%), enquanto a maioria dos professores o consideraram parcialmente adequado (56,36%). Os estudantes mostraram-se mais satisfeitos com a formação ofertada no curso atribuindo maiores valores de média para todas as dimensões e subdimensões. Referente ao perfil do egresso, professores e estudantes atribuíram o pior desempenho à subdimensão "Autônomo", o melhor desempenho foi atribuído às subdimensões "Generalista" e "Capaz de compreender a realidade social". Na dimensão Orientação do cuidado em saúde professores e estudantes atribuíram melhor desempenho àsubdimensão "Tratamento odontológico", enquanto o pior desempenho foi atribuído à "Multiprofissionalidade" e "Enfoque epidemiológico". Na dimensão Abordagem pedagógica, o melhor desempenho foi atribuído às subdimensões "Papel do professor" e "Articulação ensino-pesquisa-extensão", o pior desempenho foi atribuído por professores e estudantes àsubdimensão "Flexibilização curricular". A dimensão Integração ensino-serviço e subdimensões relacionadas foram bem avaliadastanto por professores quanto por estudantes. As principais fragilidades encontradas estão relacionadas com dimensões que abordam as relações profissional/paciente e a as relações entre o cirurgião-dentista e a equipe de saúde durante a formação profissional. Faz-se necessária a criação de estratégias de reorientação da formação direcionadas a novos conceitos metodológicos de ensino e aprendizagem para a efetivação das DCN no curso de Odontologia avaliado (AU).

The study had the purpose of evaluating, from thepoint of view of teachers and students, an undergraduate course in Dentistry, based on the National Curriculum Guidelines (NCG). This is an observational and cross-sectional study, with exploratory, descriptive and evaluative methodology. The approach used was quantitative, through the application of an online survey, by means of an instrument with validated criteria. The sample of teachers and students was a census. The "Teaching-service Integration" dimension obtained the best relative performance amongthose evaluated by both students and professors. Most students considered the course adequate to the NCG (50.2%), while most professors considered it partially adequate (56.36%). Students showed themselves to be more satisfied with the training offered inthe course, assigning higher average ratings for all dimensions and subdimensions. Regarding the "Graduate Profile", professors and students gave the worst performance to the subdimension "Autonomous"; the best performance was attributed to the subdimensions "Generalist" and "Able to Understand the Social Reality". In the dimension "Healthcare Orientation", both teachers and students evaluated the best results in the subdimension "Dental Treatment", while the worst results were attributed to the subdimensions "Multiprofessionalism" and "Epidemiological Approach". In the "Pedagogical Approach" dimension, the best performance was attributed to thesubdimensions "Professor's Role" and "Teaching-research-extension Articulation", and the worst performance was attributed by professors and students to the subdimension "Curricular Flexibility". The "Teaching-service Integration" dimension and related subdimensions were well assessed by both professors and students.The main weaknesses found are related to dimensionsthat address the professional/patient relationships and the relationships between the dental surgeon and the healthcare team during professional qualification. It is necessary to develop strategies for the reorientation of training focused on new methodological concepts of teaching and learning for the implementation of the NCG in the evaluated Dentistry course (AU).

Prevalence of mandibular asymmetry in different skeletal sagittal patterns.

OBJECTIVES: To analyze the prevalence of mandibular asymmetry in skeletal sagittal malocclusions. MATERIALS AND METHODS: PubMed/MEDLINE, EMBASE, LILACS, Web of Science, Scopus, LIVIVO and gray literature (OpenGrey, ProQuest, and Google Scholar) were electronically searched. Two independent investigators selected the eligible studies, and assessed risk of bias and certainty of evidence (GRADE). One reviewer independently extracted the data and the second reviewer checked this information. Any disagreement between the reviewers in each phase was resolved by discussion between them and/or involved a third reviewer for final decision. RESULTS: Electronic search identified 5,132 studies, and 5 observational studies were included. Risk of bias was low in two studies, moderate in one, and high in two. The studies showed high heterogeneity. Mandibular asymmetry ranged from 17.43% to 72.95% in overall samples. Horizontal chin deviation showed a prevalence of 17.66% to 55.6% asymmetry in Class I malocclusions, and 68.98% in vertical asymmetry index. In Class II patients, prevalence of mandibular asymmetry varied from 10% to 25.5% in horizontal chin deviation, and 71.7% in vertical asymmetry index. The Class III sample showed a prevalence of mandibular asymmetry ranging from 22.93% to 78% in horizontal chin deviation and 80.4% in vertical asymmetry index. Patients seeking orthodontic or orthognathic surgery treatment showed greater prevalence of mandibular asymmetry. CONCLUSIONS: Skeletal Class III malocclusion showed the greatest prevalence of mandibular asymmetry. Mandibular vertical asymmetry showed a marked prevalence in all malocclusions. However, conclusions should be interpreted with caution due to use of convenience samples and low-quality study outcomes.
