O Museu Chryso Fontes foi criado em 1953, na Faculdade de Odontologia da UFRJ, na Praia Vermelha, sendo um espaço importante para a História da Odontologia. Em 1981, com a transferência da faculdade para a Ilha do Fundão, o expressivo acervo, com mais de 2000 peças, foi guardado em instalações provisórias até recentemente. Nesse período, esforços foram envidados para preservar o acervo. O objetivo deste trabalho foi descrever as atividades do Projeto de Extensão “Espaço de Memória Chryso Fontes”, que conta com docentes e alunos de extensão, visando a identificação descritiva dos objetos, identificação dos seus estados de conservação, fotografia e digitalização das peças, visando criar um banco de dados, bem como a recuperação do acervo. Foram identificadas cadeiras, gravuras, pinturas a óleo, fotografias, livros, documentos, mobiliário e instrumentos odontológicos. Está sendo estimulada também a doação de novas peças para o acervo. Outra ação foi a criação do Instagram do Museu, sendo discutido em reuniões as cores, layouts, uma logo e nome para a página, assim como uma padronização das postagens, onde constam imagens e histórias das peças e particularidades sobre personalidades da história da Odontologia. Essas ações foram fundamentais para a recuperação do expressivo acervo, que contém peças a partir do século XVIII, visando colocá-lo novamente em exposição.

Chryso Fontes Memory Space from UFRJ: the Restoration and Cataloging of a Historical Dentistry Collection The Chryso Fontes Museum was created in 1953, at the School of Dentistry of UFRJ, in the Praia Vermelha campus, constituting an important space for the History of Dentistry. In 1981, with the transfer of the School to the Ilha do Fundão campus, the expressive collection, with more than 2000 pieces, was kept in temporary facilities until recently. In this period, efforts were made to preserve the collection. The objective of this article was to describe the activities of the Extension Project "Chryso Fontes Memory Space", in which teachers and extension students work towards identifying the objects, their state of conservation, photographing and digitalizing the pieces, aiming at the creation of a database, as well as recovering the collection. Chairs, engravings, oil paintings, photographs, books, documents, furniture and dental instruments were identified. The donation of new pieces to the collection is also being encouraged. Another act was the creation of the Museum's Instagram, with the choice of colors, layouts, the logo and name for the page being discussed between the team, as well as the patterning for the posts, containing images and stories of the pieces and particularities about personalities in the history of Dentistry. These actions were fundamental for the recovery of the expressive collection, which contains pieces from the eighteenth century, aiming to bring it back to display.

Objective: To evaluate the reliability and quality of YouTube™ videos about bruxism. Methods: Google Trends was used to determine the widely used search term on YouTube™. A playlist was created(N=100) and the number of views(NV), like/dislike(G/NG), presenter, treatments, interaction rate(TI) and views(VZ), the quality criteria for consumer health information(DISCERN) and the global quality scale index(GQS) were used. Spearman's correlation coefficient was calculated. Results: 88 videos with NV 30572.72 and G/NG 1153.76/18.31; 68(77.3%) presenters were dentists. The most cited treatment was muscle-relaxing plates; TI was 6.4 and VZ was 3658.5. Reliability was 2.82(±0.852); 21 (23.9%) were of good/excellent quality. A weak correlation between reliability/NV(rs=-0.254), the GQS/likes(rs=0.270) and the GQS/dislikes(rs=0.292). Conclusion: Content about bruxism on YouTube™ is diverse. Most of the content is presented by dentists. The information provided is moderately reliable.

To analyze the molecular composition of a sample of Baltic amber taken from an amber bracelet, verify the presence or absence of compounds beneficial to human health, and discuss the therapeutic potential of this fossil resin.

To identify the salivary metabolites profile of Mucopolysaccharidosis (MPS) types I, II, IV, and VI patients.

The present study aims to identify the salivary metabolic profile of healthy infants and young children, and to correlate this with age, salivary gland maturation, and dentition. Forty-eight children were selected after clinical evaluation in which all intraoral structures were examined. Total unstimulated saliva was collected, and salivary metabolites were analyzed by 1H Nuclear Magnetic Resonance (NMR) at 25 °C. Partial least squares discriminant analysis (PLS-DA), orthogonal PLS-DA (O-PLS-DA), and univariate analysis were used, adopting a 95% confidence interval. The study showed a distinct salivary metabolomic profile related to age and developmental phase. The saliva of children in the pre-eruption teeth period showed a different metabolite profile than that of children after the eruption. However, more evident changes were observed in the saliva profile of children older than 30 months. Alanine, choline, ethanol, lactate, and sugar region were found in higher levels in the saliva of patients before 30 months old. Acetate, N-acetyl sugar, butyrate, caproate, creatinine, leucine, phenylalanine, propionate, valine, succinate, and valerate were found to be more abundant in the saliva of children after 30 months old. The saliva profile is a result of changes in age and dental eruption, and these findings can be useful for monitoring the physiological changes that occur in infancy.

To analyze the relationship between malocclusion and bullying and its impact on the well-being and quality of life of students from low social development areas.

This study tested the null hypothesis that antihistamine-containing syrup does not change salivary metabolites in vitro and in vivo. For the in vitro experiments, saliva from 10 volunteers was mixed with a syrup or pill suspension of loratadine (1 mg/ml Claritin®, Schering-Plough, Rio de Janeiro, Brazil). For the in vivo experiment, 10 volunteers performed a mouth rinse with 10 mL of antihistamine syrup (Claritin®; Schering-Plough, Rio de Janeiro, Brazil) for 20 seconds and then discarded the rinse water. After 20 seconds, 5 mL of unstimulated whole saliva was spit into a plastic tube kept on ice. The protein profile of in vitro and in vivo experiments was analyzed using 12% sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The samples were also analyzed by nuclear magnetic resonance (NMR) spectroscopy, followed by Principal Component Analysis and Wilcoxon test (p < 0.05). There were differences in salivary metabolites after syrup interaction. The salivary concentrations of acetate, n-caproate, arginine, glutamate, and lysine among other metabolites were reduced with the syrup in both in vivo and in vitro experiments (p < 0.05), but no differences were observed when the pill suspension was used (p > 0.05). Similar changes in metabolite profiles were observed in both in vitro and in vivo experiments. Electrophoresis revealed no difference in the salivary protein pattern. The null hypothesis was rejected because the intake of syrup medicine changes the salivary composition and influences oral homeostasis and susceptibility to oral diseases.
