Abstract The objective of this study was to evaluate Brazilian dental researchers’ perceptions of research integrity and open science practices, as well as their perceptions of the way researchers are evaluated for promotion, hiring, and receiving grants. In a self-administered online survey, the respondents were presented with 3 questions on researcher evaluation in Brazil. Additionally, for 25 academic activities or characteristics, researchers rated their perceived importance for a) career advancement, b) science advancement, c) personal satisfaction, and d) social impact. The questionnaire was sent to a total of 2,179 dental researchers working in graduate programs in dentistry in Brazil. Multilevel regressions were performed to statistically confirm the differences between the predefined subgroups. Three hundred and fifty-five (16%) researchers completed the survey. Most respondents (96.1%) considered the current evaluation system to be flawed and indicated the need for improvement. Non-traditional activities were considered more important than traditional ones for science advancement (p < 0.01), and social impact (p < 0.01), whereas traditional activities were perceived to be more important only for career advancement (p < 0.01). Although Brazilian dental researchers recognize the value of open science and research integrity practices for science advancement and impact on society, they perceive that the current evaluation system emphasizes traditional activities, such as publishing many papers in well-recognized journals as criteria for advancing their careers. promotion hiring grants selfadministered self administered survey Brazil Additionally 2 characteristics b c satisfaction d 2179 179 2,17 subgroups fiftyfive fifty five 16% 16 (16% 96.1% 961 96 1 (96.1% improvement Nontraditional Non p 0.01, 001 0.01 , 0 01 0.01) 0.01. . society wellrecognized recognized careers 217 17 2,1 (16 96.1 9 (96.1 00 0.0 21 2, (1 96.

Resumo O objetivo do presente estudo foi investigar a taxa de sucesso e de sobrevivência de dentes restaurados e tratados endodonticamente (DTE) em uma clínica privada e relacionar com índices periodontais. Dados de 360 restaurações realizadas em DTE realizadas entre 2000 e 2011 foram coletados. As datas das intervenções, como restaurações, reparos, substituições e extrações foram registradas. Ainda, informações gerais relacionadas aos pacientes, aos dentes envolvidos e ao estado periodontal foram também coletadas. A taxa de sucesso foi analisada utilizando o método estatístico Kaplan-Meier e uma análise multivariada do tipo regressão de Cox foi realizada para avaliar variáveis que influenciaram na taxa de sucesso e de sobrevivência. Depois de um período de observação médio de 4,34 anos (0,6-11,6 anos), 19 dentes foram extraídos e 27 restaurações precisaram de reparo ou substituição. De acordo com a regressão de Cox, o aumento na profundidade de bolsa periodontal do dente resulta em um maior risco de falha (p=0,012). Em conclusão, a profundidade de bolsa periodontal foi considerada como um fator significativo na sobrevivência de dentes restaurados e tratados endodonticamente.

Abstract The aim of the present study was to investigate the success and survival of restored endodontically treated teeth (ETT) in a general practice environment related to periodontal parameters. Data from 360 restored ETT treated between 2000 and 2011 were collected. Dates of interventions like restorations, repairs, replacements and extractions were recorded. Additionally, general information about patients and dentitions as well as periodontal status was recorded. Success was analyzed using Kaplan-Meier statistics and a multivariate Cox regression analysis was performed to assess variables influencing success and survival. After a mean observation time of 4.34 years (range 0.6 - 11.6 years), 19 teeth were extracted and 27 restorations needed repair or replacement. According to the Cox regression, increasing maximum pocket depth of the tooth resulted in a higher risk for failure (p=0.012). In conclusion, periodontal pocket depth was found to be a significant factor in the survival of restored ETT.
