ABSTRACT

Introduction: Mouthwashes play an important role in the dental clinic, but their role on viruses requires investigation. Objective:to review in vitro studies to identify the effect of different mouthwashes on the main viruses associated with routine dental care. Methodology:The following databases were searched in September 2023: PubMed, Embase, Scopus and Web of Science databases; the Cochrane Library and the Virtual Health Library (VHL); and grey literature. In vitro studies that used mouthwashes to reduce the viral load were selected. The PICOS strategy was considered to define eligibility criteria: the Population (viruses involved in the etiology of oral infection), the Intervention (oral antiseptics), the appropriate comparator (positive and negative controls), the Outcomes of interest (reduction of viral load) and the Study design (in vitro studies). Results:Considering the eligibility criteria, 19 articles were included in this review. The efficacy of povidone-iodine (PVP-I), chlorhexidine, Listerine®, essential oils, and cetylpyridinium chloride (CPC) rinses were investigated. PVP-I (0.23%) had its effects mainly associated with coronaviruses SARS(Severe Acute Respiratory Syndrome),demonstrating a significant reduction in viral load after 15 seconds of exposure. Chlorhexidine (0.05%; 0.1% and 0.5%) was ineffective against adenovirus, poliovirus, and rhinovirus respiratory viruses. Listerine® demonstrated superior efficacy against HSV-1 and 2 viruses and influenza A, and cetylpyridine chloride also demonstrated virucidal activity against influenza A. Conclusions:The type, concentration, and time of exposure to antiseptics varied between studies. PVP-I and chlorhexidine digluconate were the most studied substances, butin general, PVP-I was more effective in reducing viral titers, especially concerning coronaviruses. Other antiseptics such as CPC, H2O2 and Listerine® have also shown significant reduction in viral load, but this is a limited number of studies (AU).


Introdução: Os enxaguantes bucais desempenham um papel importante na clínica odontológico, porém seu papel sobre os vírus requer investigações. Objetivo: revisar estudos in vitro para identificar o efeito de diferentes colutórios sobre os principais vírus associados ao atendimento odontológico de rotina. Metodologia: As seguintes bases foram pesquisadas até setembro de 2023: PubMed, Embase, Scopus e Web of Science; a Biblioteca Cochrane e a Biblioteca Virtual em Saúde (BVS); e literatura cinzenta. Foram selecionados estudos in vitro que utilizaram bochechos com o objetivo de reduzir a carga viral. A estratégia PICOS foi considerada para a definição dos critérios de elegibilidade: População (vírus envolvidos na etiologia da infecção oral), Intervenção (antissépticos orais), Comparador (controles positivos e negativos), os Desfechos de interesse (redução da carga viral) e o desenho do estudo (estudos in vitro). Resultados: Considerando os critérios de elegibilidade, 19 artigos foram incluídos para esta revisão. A eficácia da povidona-iodo (PVP-I), clorexidina, Listerine®, óleos essenciais e lavagens com cloreto de cetilpiridínio foram investigadas. O PVP-I(0.23%)teve seus efeitos principalmente associados ao coronavírusSARS (Síndrome Respiratória Aguda Severa),demonstrando uma redução significativa da carga viral após 15 segundos de exposição. A clorexidina mostrou-se ineficaz contra vírus respiratórios de adenovírus, poliovírus e rinovírus. Listerine® demonstrou eficácia superior contra vírus HSV-1 e 2 e vírus influenza A, e cloreto de cetilpiridinio também demonstrou atividade virucida contra influenza A.Conclusões:O tipo, concentração e tempo de exposição aos antissépticos variaram entre os estudos. O PVP-I e o digluconato de clorexidina foram as substâncias mais estudadas, mas no geral, o PVP-I foi mais eficaz na redução dos títulos virais, principalmente no que diz respeito aos coronavírus. Outros antissépticos como CPC, H2O2 e Listerine® também mostraram redução significativa da carga viral, mas trata-se de um número limitado de estudos (AU).

ABSTRACT

A terapia cirúrgica tem sido apontada como a estratégia mais apropriada para o tratamento da peri-implantite. Uma dessas técnicas é a implantoplastia, cuja proposta é a modificação da superfície do implante através da remoção de roscas expostas, tornando-a menos aderente ao biofilme. O estudo objetivou avaliar o efeito da implantoplastia no tratamento da peri-implantite, através da comparação entre dois grupos de intervenção: um com e outro sem implantoplastia. Assim, trata-se de um ensaio clínico prospectivo, controlado, randomizado e cego. 13 participantes com 33 implantes foram alocados aleatoriamente em dois grupos: acesso cirúrgico + debridamento mecânico (grupo controle-I) e acesso cirúrgico + debridamento mecânico + implantoplastia (grupo teste- II). Os desfechos primários foram avaliados no baseline e aos 3 meses: Índice de Placa Visível -IPV, Índice de Sangramento Gengival -ISG, Profundidade de Sondagem -PS, Sangramento à Sondagem -SS e Faixa de Mucosa Ceratinizada -MC. Avaliou- se a qualidade de vida pelo Oral Health Impact Profile -OHIP14 e também os marcadores de estresse oxidativo pelas amostras salivares. Os resultados apontaram que 69,2% eram mulheres, com idade média de 60,6 anos. Dos 32 implantes, 16 receberam a terapia I e 16 a terapia II. De todas as reabilitações, 53,8% foram totais e 30,8% foram parciais, sendo as demais unitárias. O teste de Mann-Whitney apontou que os valores de IPV e do ISG no grupo II foram maiores do que no grupo I aos 3 meses, mas não foram significativos (p=0,193; p=0,419). O SS foi maior no grupo I (50%) do que no grupo II (41,6%) aos 3 meses, porém, sem significância (p=0,759). Aos 3 meses, todos os parâmetros - exceto SS no grupo II - diminuíram de valor, sendo significativos para o IPV no grupo I (p=0,038), ISG nos grupos I e II (p=0,011 e p=0,015) e PS no grupo II (p=0,041). O ANOVA Split-Plot não mostrou interação entre tempo e tratamento. O OHIP14 mostrou que no baseline houve predomínio da "Dor física", "Desconforto psicilógico" e "Incapacidade física", enquanto que aos 3 meses houve melhora dos itens avaliados. A análise salivar mostrou que houve uma redução dos níveis de marcadores de estresse oxidativo após o tratamento, sendo significativo para o superóxido dismutase (Z=-2,701; p=0,007). Conclusão: não há evidências suficientes de que a adição da implantoplastia melhore os parâmetros clínicos no tratamento cirúrgico da peri-implantite aos 3 meses, em relação ao debridamento mecânico realizado de forma isolada (AU).


Surgical therapy has been identified as the most appropriate strategy for the treatment of peri-implantitis. One of these techniques is implantoplasty, whose proposal is to modify the surface of the implant by removing exposed threads, making it less adherent to the biofilm. The study aimed to evaluate the effect of implantoplasty in the treatment of peri-implantitis, by comparing two intervention groups: one with and the other without implantoplasty. Thus, it is a prospective, controlled, randomized and blinded clinical trial. 13 participants with 33 implants were randomly allocated into two groups: surgical access + mechanical debridement (control-I group) and surgical access + mechanical debridement + implantoplasty (test-II group). The primary outcomes were assessed at baseline and at 3 months: Plaque Index -PI, Gingival Bleeding Index -GBI, Probing Depth -PD, Bleeding on Probing -BoP, and Keratinized Mucosal Band -MK. Quality of life was evaluated by the Oral Health Impact Profile -OHIP14 and oxidative stress markers by salivary samples. The results showed that 69.2% were women, with an average age of 60.6 years. Of the 32 implants, 16 received therapy I and 16 received therapy II. Of all rehabilitations, 53.8% were total and 30.8% were partial, with the rest being single. The Mann-Whitney test showed that the values of PI and GBI in group II were higher than in group I at 3 months, but they were not significant (p=0,193; p=0,419). The BoP was higher in I group (50%) than in II group (41.6%) at 3 months, however, without significance (p=0,759). At 3 months, all parameters - except BoP in II group - decreased in value, being significant for PI in I group (p=0,038), GBI in I and II groups (p=0,011 and p=0,015) and PD in II group (p=0,041). Split-Plot ANOVA showed no interaction between time and treatment. The OHIP14 showed that at baseline there was a predominance of "Physical pain", "Psychological discomfort" and "Physical disability", while at 3 months there was an improvement in the evaluated items. Salivary analysis showed that there was a reduction in the levels of oxidative stress markers after treatment, being significant for superoxide dismutase (Z=-2,701; p=0,007). Conclusion: there is insufficient evidence that the addition of implantoplasty improves clinical parameters in the surgical treatment of peri-implantitis at 3 months, in relation to mechanical debridement alone (AU).

ABSTRACT

The distribution of harms to health varies spatially determined by the socioeconomic conditions of the environment. This research aimed to assess the spatial distribution of dental caries in 12-year-old children and their correlation with socioeconomic indicators in Brazilian states. The sample of this ecological study comprised all the 26 Brazilian states and the Federal District. Thematic and correlation maps were constructed in order to assess the spatial dependency, as well as the correlation between dental caries and socioeconomic factors. The results showed that the states with the worst DMFT indexes were located in the north and northeast, showing spatial autocorrelation. These regions also had the worst results for the following variables: poverty, illiteracy, education, and income. The bivariate analysis showed that household income and education level had negative spatial correlation with the DMFT index, while illiteracy and poverty rates showed positive correlation. Despite advances in the decline of DMFT index in recent years, there is still an inequity in the distribution of the caries disease.

ABSTRACT

Objective: To analyze the perception of undergraduates' students in a Dentistry School about the impact of basic disciplines on their professional development, as well the integration of this knowledge with the professional sphere. Material and Methods: It is a qualitative research study carried out through focus groups comprised of dentistry students close to finishing their degree. The data were analyzed by the thematic content analysis. Results: Four categories derived from the empirical material: "Disassociation of basic disciplines within the professional cycle", "Autonomy or transference of responsibility", "Campus-DOD distancing" and "Humanization of health care from first moments". The narratives showed the difficulties faced in order to effect, indeed, integration between the basic cycle and the curricular components of the vocational cycle. It was also evident the decontextualization of the basic cycle with the perspective of approach with professional practice. In addition, student's protagonist posture and learning how to humanize health care were identified as important factors to be debated and improved in the curriculum from the beginning of the course. Conclusion: The difficulties faced in order to effect an actual integration between the basic disciplines and the professional disciplines bring undesirable consequences upon undergraduate, being fundamental that the construction of new pedagogical projects means an effective integration of the contents to the curriculum design, avoiding any fragmentation between the basic and vocational cycle.

ABSTRACT

Há um reconhecimento da necessidade de mudança na educação de profissionais de saúde frente à necessidade de formar profissionais capazes de responder às demandas sociais e com isso trazer melhor qualidade de vida à população. Para isto, é fundamental discutir como o professor se insere neste contexto uma vez que é dele a responsabilidade pela condução do processo educativo. O objetivo deste estudo foi analisar a percepção de alunos do curso de graduação em Odontologia da Universidade Federal do Rio Grande do Norte (UFRN) a respeito do papel do professor no processo ensino-aprendizagem. Trata-se de estudo de natureza qualitativa, realizada por meio da técnica de grupos focais compostos por estudantes regulares dos 2º, 3º, 4º, 8º e 9º períodos, no ano 2012. Os estudantes entrevistados enfatizaram o professor como o grande responsável pelo seu aprendizado. Da análise dos dados surgiram quatro categorias: Metodologia adotada pelo professor, Relacionamento professor/aluno como influente no processo de aprendizagem, Falta de autonomia do discente e Formação docente. O estudo revelou que o professor ainda é mantido no centro do processo de ensino em função da passividade dos discentes em não assumir seu papel de corresponsáveis por sua formação, possivelmente pela postura adotada pelo professor, centrada na técnica e com pouca base em metodologias pedagógicas ativas (AU).


There is recognition of the need for change in education of health professionals to face the need to train professionals able to respond to social demands and bring with it higher quality of life for the population. For this, it is essential to discuss how the teacher fits in this context since it is their responsibility for the conduct of the educational process. The aim of this study was to analyze the perception of undergraduate students of dentistry at the Federal University of Rio Grande do Norte (UFRN) about the role of the teacher in the teaching-learning process. This is a qualitative study, conducted by the technique of focus groups composed of regular students of 2nd, 3rd, 4th, 8th, and 9th periods/semesters, in the year 2012. Respondent students em phasized the teacher as largely responsible for their learning, in so being in the center of the teaching-learning process. In analysis of the data, four categories emerged: methodology adopted by the teacher, teacher / student relationship as influential in the learning process, lack of autonomy for the student, and teacher training. The study showed that the teacher is still kept in the center of the teaching process according to the passivity of students in not taking their role as coresponsible for their learning, possibly because of the stance taken by the teacher, focused more on technique and with little basis in active teaching methodologies. In other words, not enough hands-on learning methodologies/activities are being implemented by the teachers (AU).
