Clinical trials sponsored by industry and other private organizations

Abstract The present manuscript discussed some relevant aspects related to private sponsored clinical trials in dentistry. For decades, the academy has been the major responsible for research in Brazil. Distant from the trade sector, academic research has not always provided clear benefits to society. A key aspect of making benefits clearer is the process of scientific knowledge transference to decision-makers, which is, in fact, the ground of evidence-based dentistry. Although private sponsoring of clinical research seems to be part of the research progress of the business rates, investment in Brazil is lower than those observed in other countries. It is particularly important to understand that instead of creating its own rules, dentistry imported the high-quality standards originally designed for pharmaceutical studies. Therefore, it is critical to understand the original rules and how dental items are classified by regulatory agencies. In fact, knowledge about international and local regulation is a basic assumption in industry-sponsored research. Despite globalization, the identification of industry-sponsored studies through open access databases is still very hard and time-demanding. A common concern when conducting industry-sponsored trials is study biases. Fortunately, many relevant organizations, academic and industry groups, have been working seriously against that. Finally, for less experienced researchers, many aspects related to industry-sponsored studies - such as confidentiality, authorship, budget - are deeply discussed until a final version of the trial agreement can be written and signed, protecting all sides. In short, the scenario should be improved, but it already represents a nice opportunity for dental research.

Pesquisa clínica em periodontia: princípios metodológicos e aspectos éticos / Clinical research in periodontics: methodological principles and ethical issues

O número de publicações em periodontia aumentou consideravelmente nas últimas décadas. Entretanto, uma importante proporção dos estudos clínicos recentemente publicados nacional e internacionalmente ainda apresenta erros metodológicos que afetam a sua validade. O objetivo desse artigo é apresentar princípios metodológicos que devem ser observados durante o planejamento e execução de estudos clínicos em Periodontia. Adicionalmente, aspectos éticos e de normatização serão discutidos visando garantir a integridade das evidências clínicas geradas.
