ABSTRACT
OBJECTIVES: Endodontic treatment is one of the most fearful procedures among dentistry, and the use of music during the procedure has been evaluated to control patients' anxiety. This systematic review has been conducted to provide a synthesis of the state of knowledge in this field and aimed to answer the following question: "Can music therapy reduce patient's state anxiety during endodontic treatment?". METHODS: A search was performed in six electronic databases (PubMed, Cochrane Library, Scopus, Web of Science, EMBASE, and Open Gray) for articles published until April 2022. The eligibility criteria, based on the PICOS strategy, were as follows: (P) patients undergoing endodontic treatment; (I) exposure to music; (C) no music; (O) patients' anxiety; (S) only randomized clinical trials. The risk of bias was analyzed according to the Cochrane Risk of Bias tool for randomized controlled trials (RoB 2). The strength of evidence from the included studies was assessed using the Grading of Assessment, Development, and Assessment Recommendations (GRADE) tool. RESULTS: Five eligible studies were retrieved. A low to high risk of bias was verified. Descriptive analysis showed an effect in favor of music intervention, with differences among state anxiety, heart rate and blood pressure. CONCLUSIONS: With a very low quality of evidence, dental care professionals may consider playing background music during endodontic treatment since it is a cost-effective and easy alternative to trying to reduce dental anxiety. CLINICAL RELEVANCE: Five studies were included in this systematic review and showed, with a very low quality of evidence, that music may reduce state anxiety levels on patients during root canal treatment.

INTRODUCTION: Usually, orthodontic movements encompass children and young adult patients, which are more susceptible to the occurrence of traumatic dental injuries. It is necessary to understand whether the effects of orthodontic movements on traumatized teeth could induce pulp necrosis. The aim of this study was to answer the following question: "Do orthodontic movements of traumatized teeth induce dental pulp necrosis?". MATERIAL AND METHODS: Searches were performed for studies published up to May 11, 2023, in the MEDLINE/PubMed, Cochrane Library, Scopus, SciELO Citation Index, Web of Science, EMBASE, and Grey Literature Report databases, without restriction for language or year of publication. The revised Cochrane risk of bias tools for nonrandomized interventions (ROBINS-I) was used to assess the quality of the included studies. The overall quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. RESULTS: Of 2671 potentially relevant studies, five were included. Four were classified as having a moderate risk of bias and one as a serious risk of bias. It was reported a higher susceptibility to pulp necrosis in teeth subjected to orthodontic movements with history of trauma involving periodontal tissues. Additionally, orthodontic movements of traumatized teeth with total pulp obliteration had an increased risk of pulp necrosis. GRADE analysis presented a moderate certainty of evidence. CONCLUSIONS: An increased risk for pulp necrosis when traumatized teeth are subjected to orthodontic movements was verified. However, this is based on evaluations performed with subjective tests. Further well-designed studies are necessary to confirm this trend. CLINICAL RELEVANCE: Clinicians must be aware of the possibility of pulp necrosis. However, endodontic treatment is recommended when verified signs and symptoms of pulp necrosis.

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).

Objetivos: Avaliar três protocolos de irrigação final para remoção de detritos e material obturador de istmos simulados. Métodos: Setenta e oito pré-molares foram preparados com o sistema WaveOne Gold 45.05. Os dentes foram seccionados longitudinalmente e um istmo padronizado foi confeccionado no terço apical. Seis raízes foram utilizadas como controle negativo. Os espécimes foram randomizados em dois grupos principais (n=36). Trinta e seis raízes tiveram o istmo preenchido com detritos e as outras trinta e seis raízes foram obturadas com guta-percha e cimento endodôntico, por meio da técnica híbrida de Tagger. Cada grupo foi dividido em três subgrupos (n=12), de acordo com o protocolo de irrigação final: Easy Clean; irrigação ultrassônica passiva (PUI); e XP Clean. A ativação do NaOCl 2,5% pelo Easy Clean foi realizada em três ciclos de vinte segundos; e pelo XP Clean, por um minuto em movimento reciprocante e contínuo, respectivamente. No grupo PUI, o irrigante foi ativado em três períodos de vinte segundos. Resultados: Não foi encontrada associação entre os escores de remoção de detritos e os protocolos de irrigação (p=0,165). Foi observada associação entre os escores de remoção do material obturador e os protocolos de irrigação final (p<0,05). Conclusões: Os protocolos de irrigação final foram efetivos para a remoção de detritos, mas não para remoção de material obturador de istmos no terço apical (AU).
This study aimed to assess three final irrigation protocols on debris and filling removal from simulated irregularities. Methods: Seventy-eight mandibular premolars were prepared with WaveOne Gold system 45.05, splitted longitudinally, and a standardized groove was performed in the apical portion of the canals. Six roots served as negative control. The roots were randomly divided into two main groups (n = 36). The grooves were filled with dentin debris in thirty six roots. The others thirty-six were filled with gutta-percha and endodontic sealer using Tagger hybrid technique. Each main group was then divided into three groups (n = 12) according to the final irrigation protocol: Easy Clean, passive ultrasonic irrigation (PUI), and XP Clean. In Easy Clean 2.5% NaOCl activation was performed for 3 cycles of 20 seconds and XP Clean for one minute under reciprocating and continuous rotary motion and continuous rotary motion, respectively. In the PUI group, the irrigant was activated in three periods of 20 seconds. Results: No association was found among the scores of debris removal and the irrigation protocols (p = .165). An association was observed among the filling material removal scores and irrigation protocols (p< .05). Conclusion: Easy Clean, PUI and XP Clean were effective for dentin debris removal, but did not for filling material from artificial grooves in the apical third (AU).

The aims of this study were to evaluate the physical and chemical properties, cytotoxicity and dentinal tubule penetration of a new calcium silicate-based root canal dressing. For pH and calcium ion release evaluation (1, 24, 72 and 168 h) were used a pH meter and colorimetric spectrophotometer, respectively. Radiopacity evaluation followed the ISO 6876:2012. Cytotoxicity was evaluated by the percentage of cell viability using MTT assay. Illustrative images of dentinal tubule penetration were obtained using confocal laser scanning microscopy (CLSM). Data from pH and calcium ion release were statistically analyzed by two-way analysis of variance and Tukey test. Radiopacity was analyzed using the Student t-test. The statistical tests for cytotoxicity results were the one-way analysis of variance and Tukey test. Both materials showed alkaline pH in all experimental times. The pH values for calcium hydroxide paste were higher than bioceramic paste at 1, 24, and 72 h (p<0.05). The calcium ion release of bioceramic was lower than the calcium hydroxide paste only at 24 h (p<0.05). The bioceramic was more radiopaque than the calcium hydroxide paste (p<0.05). Bioceramic paste presented a dose and time-dependent cytotoxic effect after MTT assay. CLSM images showed absence of tubule penetration for both pastes. The new calcium silicate-based canal dressing presented alkaline pH, high calcium release, and acceptable radiopacity. Bio C Temp showed a dose and time-dependent cytotoxic and absence of dentinal tubule penetration.

This study aimed to evaluate penetrability on dentinal tubule of a new bioceramic sealer through confocal laser scanning microscopy (CLSM). A specific fluorophore (Fluo-3) was mixed with the sealer. Forty distobuccal roots from maxillary molars were selected, and root canal preparation was carried out with Wave One Gold # 35.06 instruments. Roots were randomly assigned to 4 groups according to the filling procedures: Bioceramic/Lentulo (Sealer Plus BC); Bioceramic/EasyClean group, three activation of the sealer (3x20 s) with Easy Clean instrument; Bioceramic/Irrisonic: ultrasonic activation for 30 s; and AHplus/Lentulo: epoxy resin based sealer (AH Plus) was utilized with the same protocol as the BC/LE group. After 72 h, specimens were transversally sectioned at 2 and 7 mm from root apex and then analyzed through CLSM. Sealer penetration area on dentinal tubule was measured by Adobe Photoshop CC2018. Kruskal Wallis and Wilcoxon T tests were carried out. Penetrability results were similar for both sealers regardless of which technique was performed to activate them inside the root canal (p>0.05). It is reasonable to conclude that penetration of bioceramic and epoxy resin based sealers occurred unimpressively. The type of instrument used to activate bioceramic sealer did not affect penetrability. Fluo 3 should be recommended as the fluorophore to evaluate dentinal tubule penetration of bioceramic sealers.

The aim of this study was to evaluate the effect of 95% ethanol irrigation, with 5 or 10 min of action, on the antibacterial properties of 2% chlorhexidine (CHX), on oral biofilm, evaluated with confocal laser scanning microscopy (CLSM). Oral biofilm development was induced in 80 sterilized bovine dentin blocks, distributed in two groups (5 or 10 min) and 4 subgroups, according to time and the solution used: Saline (SALINE5, SALINE10); Saline followed by CHX (SALINE/CHX5, SALINE/CHX10); Ethanol (ETHANOL5, ETHANOL10), Ethanol followed by CHX (ETHANOL/CHX5, ETHANOL/CHX10). The surface of the block was dyed with Live/Dead® BacLight. Images from different areas were analyzed by BioImage L program. The total biovolum (µm³), biovolum of live cells (green), percentage of live cells of the thickness of the biofilm visualized in CLSM and on surface biofilm were evaluated. Total biovolum and biovolum of living cells showed similar results among the different groups (p > .05). The percentage of living cells in total thickness of the biofilm also was similar among the groups (p > .05), except ETHANOL5, SALINE/CHX10, ETHANOL10, and ETHANOL/CHX10 that showed lower percentage than SALINE5 (p < .05). The ETHANOL10 and ETHANOL/CHX10 also showed lower percentage of living cells than ETHANOL/CHX5 and SALINE10 (p < .05). In relation to biofilm surface, SALINE/CHX5, SALINE/CHX10, ETHANOL5, ETHANOL10, ETHANOL/CHX5, and ETHANOL/CHX10 showed a lower percentage of living cells percentage than SALINE5 and SALINE10 groups (p < .05). Therefore, ethanol has no effect on antimicrobial properties of 2% chlorhexidine, prior when used as endodontic irrigating solution.
