Effect of Robusta Coffee Bean Extract as Immunoregulator on Dental Pulp Mesenchymal Stem Cells via Paracrine Pathway
Get PDFObjective: To analyze the effect of Robusta Coffee Bean Extract (RCBE) on Dental Pulp Mesenchymal Stem Cells (DPSCs) culture in secreting cytokines, growth factors, and cell differentiation. Material and Methods: DPSCs culture from premolar human teeth only and DPSCs culture from premolar human teeth given RCBE with concentrations of 0.0625%, 0.125%, 0.25%, and 0.5% for 24 hours, 48 hours, and 72 hours. The secretome of the DPSCs culture was examined for TNF-α, IFN-g, IGF, and VEGF, examination of SOX2 and Oct4, and Wnt differentiation markers by ELISA. Statistical analysis used ANOVA and continued with LSD. Results: There was a significant reduction in the levels of TNF-α and IFN-g at 0.25% RCBE concentration at 72 hours of immersion (p<0.05). Growth factor levels of IGF and VEGF increased when given 0.25% RCBE compared to the other groups, and the differentiation markers SOX2 and Oct4 and Wnt also increased at a concentration of 0.25% at 72 hours of immersion (p<0.05). Conclusion: Giving RCBE with a concentration of 0.25% can reduce inflammatory cytokines and increase growth factors and differentiation markers in DPSCs cultures
Prevalence of Craniofacial Anomalies - 14 Years of Experience in a Brazilian Referral Service
Get PDFObjective: To delineate the frequency of congenital craniofacial anomalies (CCAs) in a Brazilian reference center. Material and Methods: A cross-sectional, retrospective epidemiological study was conducted, updating information from the reference center. Data were extracted from the medical records of patients assisted between January 2009 and December 2022 at the Craniofacial Anomalies Rehabilitation Center (Centro Pró-Sorriso) in Alfenas, Brazil. Previous studies were used as a reference for the classification of CCAs. Data were analyzed using statistical software for absolute and relative frequency descriptive analysis. A 95% confidence interval was adopted. Study approved by ethics and research committee. Results: 817 records were analyzed, comprising 53.5% males and 46.5% females. Identified 954 congenital anomalies (CAs); of these, 86.9% of cleft lip and/or palate (CL/P), 16.0% of CAs without CL/P, and 2.8% of syndromes or sequences recognized in the absence of CL/P. The CAS most commonly associated with any CL/P were cardiovascular system anomalies (23%), and the most common CL/P was cleft palate (48.7%). Conclusion: Among the CAs, CL/P was the most prevalent, exhibiting a higher ratio in males. Following CL/P, ear anomalies were the most commonly observed; however, when associated with the presence of any CL/P, cardiovascular system anomalies were more numerous. Regarding the presence of syndromes and/or sequences, Goldenhar Syndrome was more prevalent in cases without an association with clefts
A Comprehensive Survey of Natural Smile Perception
Get PDFObjective: To comprehensively analyze smile perception by examining various smile parameters and identifying potential group differences. Material and Methods: A cross-sectional study was conducted utilizing a photographic-based electronic survey. Participants\u27 demographic data were collected, and their perception of smile photos, altered across 12 parameters, was assessed using a Likert scale. The study included laypersons, dental students at different academic levels, and dental professionals. Statistical analyses were performed to analyze ratings and determine group differences. The significance level was set at 0.05. Results: A total of 435 participants completed the survey. Neither ordinal regression nor linear regression yielded any significant associations between individual photos and perception across groups (p>0.05). However, chi-square analysis revealed six events with statistically significant differences among groups, with laypersons exhibiting significant differences in four of them (p=0.009, p=0.012, and p=0.017). Conclusion: The limited statistically significant differences in perception between the study groups could be a consequence of the naturally-looking photo edits that may have posed challenges in recognizing subtle alterations and eye fatigue from viewing numerous duplicate photos. Future research should address such limitations to enhance our understanding of smile perception across diverse groups

In Vitro Analysis of the Accuracy of Intraoral Scanning in Children
Get PDFObjective: To evaluate the accuracy of intraoral scanning in maxillary dental arches of children. Material and Methods: Twenty-five edentulous dental models (Group 1) and 25 dental models with complete deciduous dentition (Group 2) comprised the sample sets. An intraoral scanner was used to scan plaster models and thus obtain virtual models. Intercanine and intertuberosity distances, as well as anterior and posterior lengths (right and left), were evaluated using a digital caliper and software. Maximum, Minimum, Mean, and Root Mean Square (RMS) were the quantitative parameters evaluated of the superimposition between repeated scans. Paired t-test, independent t-test, intraclass correlation coefficient (r), Mean Absolute Difference (MAD), Technical Error of Measurement (TEM), and Relative Percentage Error (RPE) were used. Results: Methodological reliability showed no statistically significant difference (p>0.05). In both groups, there was no statistically significant difference between the compared methodologies (p>0.06), and it also showed r = 0.970 to 0.996. The MADs were equal to or less than 0.08 in both groups. The TEM ranged from 0.147 to 0.199 in Group 1 and 0.119 to 0.224 in Group 2. The RPE in the samples evaluated was excellent (RPE < 1%). The RMS of the superimposition between the scanned surfaces showed excellent values inferior to 0.10 mm. Conclusion: The use of intraoral scanner equipment is essential for professionals who provide pediatric dental care to know the accuracy of an impression method that makes the child\u27s clinical procedure safer, more precise, faster, comfortable, and playful
Contextual Analysis of Hiring Dentists in Dental Specialty Centers in Brazil
Get PDFObjective: To analyze the contextual characteristics of labor contracts of dentists in Dental Specialties Centers (CEOs). Material and Methods: Data from the PMAQ-CEO in its 2nd cycle were explored and all 1,097 CEOs in Brazil were evaluated on-site in 2018. The data were analyzed through descriptive statistics, bivariate analysis by Pearson\u27s chi-square test, binary logistic regression, and adjusted through the Wald stepwise backward procedure. Results: The adjusted model of the binary logistic regression showed that Type I (OR=2.253) and Type II (OR=2.558) CEOs have more than double the odds of having all dental surgeons with statutory employment. CEOs located in municipalities with high Human Development Index (>0.699) and large population size (More than 100,000 inhabitants) exhibit 4.2 times and 2.3 times higher odds of having all dental surgeons with statutory employment (OR=4.208 and OR=2.332). When analyzing the types of contracting agents that are not direct administration: according to the population size, it was observed that the intermunicipal consortium of public/private law is proportionally more present in municipalities with 50 to 100 thousand inhabitants. Conclusion: Although the states in the Northeast region of Brazil have presented the highest rates of implanted CEOs, these are the locations with lower HDI and are the most exposed to non-statutory links

RELATO DE SUCESSO: ESTRATÉGIAS PEDAGÓGICAS PENSADAS PARA UMA ESTUDANTE COM TEA NO PRIMEIRO SEGMENTO DO ENSINO FUNDAMENTAL
Get PDFEste artigo tem como objetivo apresentar o trabalho de alfabetização realizado com uma estudante dentro do transtorno do espectro autista (TEA) nível de suporte I. Ressaltamos os avanços e possibilidades em relação a construção de sua leitura e da escrita por meio de adequações e possibilidades pedagógicas pertinentes aos conhecimentos do 3º ano de escolaridade do ensino fundamental I embasado na tecnologia assistiva Desenho Universal de Aprendizagem (DUA). Pontuamos que as atividades foram desenvolvidas por Projetos interdisciplinares, priorizando a maior quantidade de atividades em comum com a turma. Assim, compreendemos que as atividades pedagógicas podem proporcionar a compreensão e serem praticadas por todos os estudantes da turma, independentemente de suas capacidades cognitivas ou linguísticas. O resultado da experiência citada foi a conquista da construção da leitura e da escrita da estudante em questão, bem como do desenvolvimento de seu raciocínio lógico, e sua autonomia para ler as produções propostas para o 3º ano, com adequação da maioria dos textos de acordo com a proposta do DUA. Destaca-se a conquista leitora da estudante sobre os diferentes tipos de fontes de letras, bem como a autonomia para realização de suas produções textuais. Dessa forma, concluímos sobre a importância de respeitar às diferenças, ouvir os estudantes e entendê-los como produtores de currículo, refletindo sobre possíveis estratégias para seu desenvolvimento, tais como o DUA; as adequações curriculares; a mudança da perspectiva da questão do erro como potente para a aprendizagem e a atenta observação dos discursos dos estudantes. 
LESMA: UM ESPAÇO PEDAGÓGICO POSSÍVEL NA EDUCAÇÃO MATEMÁTICA CRÍTICA DE PESSOAS PLURIVERSAS SURDAS
Get PDFEste artigo tem como finalidade esboçar a minha trajetória como professor pesquisador na Educação de Surdos para o desenvolvimento de estudos e de práticas pedagógicas elaboradas para os anos finais do Ensino Fundamental exercidas durante o período de instauração do projeto do Laboratório de Estudos Surdos em Matemática – Lesma, na Escola Bilíngue Prof. Alfredo Dub, na cidade de Pelotas/RS. De maneira concisa, procuro descrever as experiências de trabalho realizadas no decorrer deste projeto e busco refletir e compartilhar algumas intervenções teóricas e práticas com o propósito de contribuir para a Educação de Surdos e para a Educação Matemática por um viés crítico e democrático nos espaços da Educação Inclusiva. O projeto viabilizou não somente a produção do conhecimento compartilhado nos estudos na área das exatas no contexto do Ensino Fundamental, como contribuiu para emergir discussões sobre temáticas que, muitas vezes, situam-se à margem de questões curriculares que circundam, predominantemente, por debates culturais, identitários e linguísticos na Educação de Surdos. O Lesma, efetivamente, preponderou por um currículo e um planejamento com ações pluriversas reconhecendo as interseccionalidades que atravessam também a Comunidade Surda e, consequentemente, promover a Educação Matemática Bilíngue Crítica
