A map of Brazilian dental research in the last decade

Abstract

The aim of the present study was to analyze dental research trends in Brazil over the past nine years. All abstracts presented at the 26th Annual Meeting of the Brazilian Society for Dental Research in 2009 (n = 2648) were classified based on field of knowledge, home institution and geographic region. Data were compared with those previously published based on abstracts presented at various meetings. Between 2001 and 2006, five fields of knowledge had a greater than 10% representation among the total number of studies. These fields included restorative dentistry/dental materials (RD/DM), periodontics, endodontics, pediatric dentistry and population-based oral health. In 2009, only RD/DM maintained a greater than 10% proportion of meeting abstracts, and basic fields comprised the second position among those fields with greater representation (9.8%). The majority of research studies were performed at public institutions, and the number of abstracts per state increased significantly in 2009 (Wilcoxon test, p < 0.001). The southeastern region of Brazil submitted the greatest number of abstracts; however, other regions also demonstrated increased participation in research (11%). The percentage distribution of abstracts between states remained constant (Wilcoxon test, p = 0.255; r s = 0.873). The results of the present study suggest a slight shift in the scientific research profile in Brazilian dentistry: fields related to professional disciplines have declined in relative research participation, while increasing interest has been observed in basic fields and new specialties.
