Due to the COVID-19 pandemic crisis, many dental schools and instructors are rethinking the way they teach and interact with students. New perspectives regarding a change in face-to-face activities, social isolation and the reformulation of clinical activities result in a transition toward e-learning and e-teaching processes. In this review, we discuss some favorable aspects and difficulties associated with virtual teaching and learning, searching for available tools and techniques as well as new perspectives.
Denture stomatitis (DS) is frequently associated with high levels of Candida in saliva and deficient denture hygiene. In order to analyse the incidence of DS and its pre-disposing factors, we evaluated 77 edentulous patients before and 6 months after the placement of new complete dentures. Denture stomatitis was observed in 50.6 and 18.2% of the patients at the first and second evaluation, respectively. Salivary flow, Candida counts in saliva and Candida species were similar in both evaluations. Denture stomatitis and Candida in saliva were more common in females. Our results showed that denture replacement and denture hygiene improvement were useful for DS resolution, particularly types I and II. However, oral and denture hygiene must be continuous, inasmuch as salivary Candida counts remained high and it is considered an important pre-disposing factor for DS.
The aim of the present study was to analyze the prevalence of nonsyndromic oral clefts in children receiving treatment at the Center for the Rehabilitation of Craniofacial Anomalies, José do Rosário Vellano University, Alfenas, MG, Brazil. All the data for the epidemiological study was retrieved from the files of 126 pediatric patients with oral clefts without any additional malformation, who came to the center for treatment between 2000 and 2005. A predominance of clefts was observed in Caucasians, and the ratio of male to female was 1.3. Males were 2.57 times more affected by cleft lip and palate (CLP) than females. CLP with a prevalence of 39.68% and isolated cleft lip (CL) with a prevalence of 38.09% were the most common anomalies, followed by isolated cleft palate (CP; 22.23%). Complete and unilateral CLP (26.19%) presented the highest prevalence, followed by incomplete and unilateral CL (23.81%). The present study presents the experience of a reference hospital in the state of Minas Gerais; however, the real prevalence of oral clefts in Brazil is still unknown. Our findings differ from those of a few previous Brazilian reports because they suggest similar prevalences of CLP and CL, and a higher prevalence of CLP in Caucasian males.
Head and neck cancer patients need to receive dental care previously to radiotherapy. Even patients who regularly visit dental offices need special attention including prophylactic and curative treatments. The purposes of this study were to evaluate the dental status of Brazilian head and neck squamous cell carcinoma patients with low socioeconomic level as well as to discuss the dental treatment performed and the oral side effects of radiotherapy. Forty patients with head and neck squamous cell carcinoma received dental care and dental extractions prior to radiotherapy and were were followed up for a mean period of 28.7 months after the cancer treatment. Before radiotherapy, 28 patients were dentulous and 12 edentulous, and all of them had poor oral health and hygiene. The most common treatment performed were dental extraction and 23 patients had 8.6 teeth extracted on average. One out of 9 (11.1%) patients developed radiation caries and 5 out of 23 cases (21.3% - Group I) developed osteoradionecrosis, being only 1 case associated with previous dental extraction. Brazilian low-socioeconomic level patients with head and neck cancer were submitted to multiple dental extractions due to poor dental conditions and inadequate oral care. The dental treatment did not prevent osteoradionecrosis, which presumably presented a multifactorial etiology in most cases.
Pesquisadores brasileiros têm demonstrado aumento na produção científica associada à publicação de trabalhos na literatura corrente. O objetivo desse estudo foi compreender o perfil de pesquisadores brasileiros voltados para a odontologia com bolsas de produtividade concedidas pelo Conselho Nacional de Pesquisa (CNPq). Para revelar o perfil, 132 Currículos Lattes de pesquisadores, durante 2003 a 2005, foram cuidadosamente analisados, e variáveis como gênero, classificação no CNPq (1A a 1D, 2), instituição de origem, tempo de doutorado, artigos publicados com o respectivo Qualis, livros e capítulos de livros, orientações de mestrado e doutorado e áreas de atuação foram catalogados. O perfil geral foi formado por homens (64,39%), classificação classe 2 (42,42%), concentrados em instituições do Estado de São Paulo (85,6%), com 10 a 15 anos de doutorado (32.57 %), publicando em periódicos Qualis A Internacional e Qualis B Nacional. A produção de livros ou capítulos de livros, orientações de mestrados ou doutorados foram heterogêneas. A visão geral revelou uma produção consistente associada a grupos de pesquisadores consolidados.
O objetivo deste estudo foi descrever o perfil epidemiológico dos acidentes ofídicos da macrorregião de saúde do Norte do Estado de Minas Gerais, Brasil. Foram analisadas informações sobre os acidentes ofídicos relativos ao período compreendido entre janeiro de 2002 a dezembro de 2006, por meio de bancos de dados. Os resultados demonstraram 10.553 casos notificados, com ênfase para a maior casuística em meses de tempo quente e chuvoso, em áreas urbanas (54,1%), faixa etária menor de 20 anos (39,7%), acometendo mais homens e estudantes (53,1% e 29,1%) respectivamente. Os membros inferiores (pé, dedo do pé, perna e coxa) foram os locais mais afetados (35,9%), as serpentes prevalentes foram do gênero Bothrops (82,9%) e a gravidade da maioria dos acidentes foi leve (66,2%). Observou-se nesse estudo um importante impacto da sazonalidade, urbanização, subnotificação das espécies envolvidas nesses acidentes e busca rápida pelo pronto atendimento. Espera-se que os dados inéditos da casuística obtida possam servir de substrato para o planejamento e execução de medidas voltadas para vigilância em saúde e atendimento.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
