Wanted: A Base of Evidence

  • The Editorial Board of the Journal of Endodontics
      The quest for a scientific basis upon which to make clinical decisions is prominent in our efforts to continually improve health care. Evidence-based dentistry, which relies on a comprehensive, reliable and high quality body of science, offers valuable guidance to the practice of endodontics. In evidence-based dentistry, published studies are assigned a level of evidence (LOE), a relative ranking system that is based on the potential impact of study design on resulting clinical implications. The highest level of evidence comes from analyses of prospective, double blind, randomized controlled clinical trials (RCT), the gold standard of science. The lowest level of evidence is represented by the single clinical case report. In general, “bench top” or in vitro studies are rarely considered when developing LOE.
