RESUMO

This systematic review and network meta-analysis aimed to answer the following focused research question: "Does the type of endodontic sealer affect the postoperative pain in patients who received endodontic treatment?" Different databases and grey literature were surveyed. Only one randomized controlled trial were included. The risk of bias in the studies was evaluated by using the Cochrane Collaboration's tool. A random-effects meta-analysis was conducted to compare the risk and intensity of postoperative pain. The quality of the body of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. Out of 11,601 studies, 15 remained for qualitative analyses and 12 for meta-analysis. Seven studies were classified at high risk of bias, and 8 studies raised some concerns. No significant differences between the endodontic materials were observed in the direct comparisons, both in risk and in intensity of postoperative pain (pairwise comparisons with 2 studies: I2 = 0%; p > 0.05 and 8 studies: I2 = 23%; p > 0.05, respectively). The certainty of the evidence was graded as low or moderate. There was no difference in the risk and intensity of postoperative pain after filling with different endodontic sealers. Further systematic reviews should be conducted. Trial Registration: PROSPERO Identifier: CRD42020215314.

RESUMO

OBJECTIVES: This study aims to investigate the compliance of randomized controlled trials (RCTs) in posterior restorations with the Consolidated Standards of Reporting Trials Statement (CONSORT) statement and to analyze the risk of bias (RoB) of these studies. METHODS: A systematic search was performed in PubMed, Scopus, Web of Science, LILACS/BBO, and Cochrane Library. Only RCTs published in peer-reviewed journals were included. The compliance with the CONSORT was evaluated in a 0-2 scale where 0 = no description, 1 = poor description and 2 = adequate description. Descriptive analyses of the CONSORT mean score by journal, country, and RoB were performed. The RoB in RCTs was evaluated by using the Cochrane Collaboration's tool version 1.0. RESULTS: A total of 15,476 studies were identified after duplicates removal. O only 202 meet the eligibility criteria, among which 31 were follow-up studies. Concerning the overall RoB, only 29 out of 171 were classified as low risk of bias. The overall mean CONSORT score was 19 ± 5.4 points, which means compliance of approximately 59%. Significant differences among countries, publication period, and RoB were observed (p < 0.001). The journal's impact factor was not correlated with the overall CONSORT score (p = 0.36). CONCLUSIONS: The adherence of RCTs conducted in posterior restorations to the CONSORT Statement is still low. In addition, most studies were classified as at unclear risk of bias. These results call up an urgent need for improvement. CLINICAL RELEVANCE: Most RCTs conducted in posterior teeth have poor reporting and are mainly classified as having an unclear risk of bias.

RESUMO

Introdução: o sono é essencial à sobrevivência e sua função principal é a restauração física e mental. Objetivo:avaliar a qualidade do sono em alunos de graduação matriculados em cursos de diferentes áreas daUniversidade Federal do Ceará ­ Campus Sobral. Métodos: estudo transversal que investigou a qualidade dosono em alunos de Engenharia Elétrica, Odontologia e Música, por meio da aplicação de questionários: Índicede Qualidade do Sono de Pittsburgh e Escala de Sonolência de Epworth. Os dados foram decodificadosno programa Microsoft Office Excel e expressos em frequência absoluta ou relativa no software GraphPadPrism 5. Resultados: a frequência de boa qualidade de sono foi de 32,67%; de qualidade ruim, 45,54%; e21,78% pontuaram em distúrbios do sono. A Engenharia apresentou maior qualidade de sono ruim (54,55%)e distúrbio do sono (27,27%); a Odontologia, 44,93% de qualidade de sono ruim; já no curso de Música, aboa qualidade do sono foi consideravelmente alta (53,97%) em relação aos demais. Os piores índices foramdo início e do meio da graduação, sendo elevados para sonolência diurna excessiva em todos os cursos.Conclusão: acadêmicos, principalmente de Odontologia e Engenharia Elétrica, apresentaram qualidade desono ruim, altas prevalências de distúrbios do sono e sonolência diurna excessiva.(AU)

Introduction: sleep is essential for survival and its main function is physical and mental restoration. Objective: to evaluate the quality of sleep in undergraduate students enrolled in courses in different areas at the Federal University of Ceará - Campus Sobral. Methods: cross-sectional study that investigated sleep quality in electrical engineering, dentistry and music students through the application of questionnaires: Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale. The data were decoded in the Excel Microsoft Office program and expressed in absolute or relative frequency in the GraphPad Prism 5 software. Results: the frequency of good sleep quality was 32.67%; of poor quality, 45.54% and 21.78% scored in sleep disorders. Engineering showed higher quality of bad sleep (54.55%) and sleep disturbance (27.27%); Dentistry, 44.93% of poor sleep quality; in the music course, the good quality of sleep was considerably high (53.97%) in relation to the others. The worst rates were at the beginning and middle of graduation, being elevated for excessive daytime sleepiness in all courses. Conclusion: academics, mainly in Dentistry and Electrical Engineering, had poor sleep quality, high prevalence of sleep disorders and excessive daytime sleepiness.(AU)
