The fourth international collaborative study "An international comparative study for clarifying the mechanism of the evidence-practice gap and planning improvement strategies" has been started. This study is funded by JSPS KAKENHI Grant (Principal Investigator: Naoki Kakudate, Kyushu Dental University).
  This is the first international collaborative study between Japan and Brazil. Data collection in Brazil is being conducted by Dr. Elaine Pereira da Silva Tagliaferro, Professor of Dentistry at São Paulo State University (Unesp). The questionnaires were developed by the JDPBRN in Japanese and Brazilian languages, partially referring to the Practice Impact Questionnaire developed by the National Dental PBRN in the United States.
  The ultimate goal of this study is to identify the mechanisms underlying the evidence-practice gap between the two countries and to recommend measures to improve it.

In Brazil, a new Dental PBRN has been established, named "42clinics (https://www.fop.unicamp.br/42clinics/index.php/pt/)". Dr. Valeria V. Gordan (Professor at the University of Florida College of Dentistry) of US National Dental PBRN introduced Dr. Elaine Pereira da Silva Tagliaferro (Professor at the School of Dentistry, São Paulo State University - Unesp), a steering committee member of 42clinics, to JDPBRN. We are happy to congratulate 42clinics on its establishment. From the JDPBRN Steering Committee, we sincerely wish for the future success of 42clinics.
