Taxa de publicação de resumos da área de Endodontia apresentados na Sociedade Brasileira de Pesquisa Odontológica entre 2013 e 2016 / Full-length publication rates of endodontic abstracts presented at the Brazilian Society of Oral Research meetings between 2013 and 2016

O conceito de Odontologia baseada em evidências requer a produção e publicação de pesquisas de alta qualidade em periódicos internacionais criteriosos. Objetivo: O presente estudo teve como objetivo avaliar as taxas de publicação de resumos endodônticos apresentados na reunião da SBPqO nos anos de 2013, 2014, 2015 e 2016. Material e Métodos: O fator de impacto e a classificação Qualis dos periódicos, e o tempo decorrido entre o congresso e a publicação completa também foram avaliados. Em seguida, foram classificados em seis categorias: pesquisa básica endodôntica, revisão de temas endodônticos, estudos clínicos, ensaios clínicos randomizados, pesquisa básica tecnológica ou relatos de caso. Uma pesquisa em bancos de dados eletrônicos usando o mecanismo Medline (PubMed) foi realizada de janeiro de 2018 a julho de 2018, para identificar publicações escritas em inglês com texto completo dos resumos endodônticos previamente selecionados. A identificação da publicação em texto completo dos resumos foi inicialmente realizada utilizando o sobre- nome do primeiro autor e as principais palavras-chave do título do resumo. Após a verificação do artigo em texto completo, informações adicionais foram registradas, tais como: tempo decorrido até a publicação; nome, fator de impacto e classificação Qualis da revista; e o tipo de estudo. Resultados: Após a leitura do conteúdo da reunião, 1.238 resumos (10,2%) foram considerados de interesse endodôntico e, em seguida, foi realizada uma busca eletrônica no banco de dados. Conclusão: Um grande número de resumos endodônticos não foi publicado como um manuscrito completo. Estudos clínicos e ensaios clínicos randomizados representaram uma pequena parte das publicações (AU).

Evidence-based dentistry consists in the clinical application of concepts based on researches pub- lished as scientific papers in indexed periodicals. Objective: This study aimed to evaluate the publication rates of endodontic abstracts presented in the meeting of SBPqO in the years of 2013, 2014, 2015 and 2016. Materials and Methods: Endodontic abstracts presented between 2013 and 2016 were included. Then, they were classified into six categories: endodontic basic research, review endodontic topics, clinical studies, randomized clinical trials, technological basic research or case reports. An electronic database search using the Medline (PubMed) engine was performed from January 2018 to July 2018 to identify full-text English-written publications of the endodontic abstracts previously selected. The identification of full-text publication of the abstracts was initially performed using the first authors last name and the main keywords from the title of the abstract. Following full-text article verification, additional information was recorded such as: elapsed time until publication; name, impact factor and Qualis classification of the journal; and type of study. Results: After reading the content of the meeting, 1,238 abstracts (10.2%) were considered to be of endodontic interest, and then an electronic database search was performed. Conclusion: A large number of endodontic abstracts were not published as a full-length manuscript. Clinical studies and randomized clinical trials represented the small part of the publications (AU).

Intratubular penetration of endodontic sealers depends on the fluorophore used for CLSM assessment.

Root canal filling aims at eliminating empty spaces into the root canal system using biologically compatible materials. Three-dimensional root canal obturation must prevent or minimize the reinfection caused by microorganisms' leakage. This study aimed at evaluating whether fluorophore (Rhodamine or Fluo-3) influences the CLSM images of intratubular penetration of four endodontic sealers. Eighty bovine teeth were prepared using K files up to a size #70 and irrigated with 2.5% sodium hypochlorite. All roots were divided into eight groups (n = 10) according to the sealer and fluorophore used: AH Plus/Rhodamine, AH Plus/Fluo-3, Sealer Plus/Rhodamine, Sealer Plus/Fluo-3, Sealer Plus BC/Rhodamine, Sealer Plus BC/Fluo-3, Endosequence/Rhodamine, and Endosequence/Fluo-3. All roots were filled using cold lateral compaction technique. After 7 days, the roots were transversely sectioned, and three slices, one of each canal third, were obtained. Intratubular penetration was evaluated using CLSM. Sealer Plus BC/Rhodamine and Endosequence BC/Rhodamine presented higher intratubular penetration than AH Plus/Fluo-3 and Sealer Plus/Fluo-3 (p ˂ .05). The intragroup analysis showed similar intratubular penetration, regardless of the root third, except for the apical third in AH Plus/Fluo-3 and Sealer Plus BC/Fluo-3 groups. The type of fluorophore influences the calcium silicate sealers' tubular penetration but not of epoxy resin-based ones using CLSM. Bioceramic sealers should not be used associated with Rhodamine for CLSM evaluation. RESEARCH HIGHLIGHTS: The type of fluorophore influences the calcium silicate sealers' tubular penetration but not of epoxy resin-based ones when CLSM is used for assessment. Bioceramic sealers should not be used associated with Rhodamine.
