Generating and implementing evidence-based policy is an important aim for many publicly funded health systems. In dentistry, this is based on the assumption that evidence-based health care increases the efficiency and effectiveness of interventions to improve oral health at a population level. This article argues that a linear logic model that links the generation of research evidence with its use is overly simplistic. It also challenges an uncritical interpretation of the evidence-based paradigm and explores approaches to the evaluation of complex interventions and how they can be embedded into policy and practice to improve oral health at a population level.
Keywords: Evidence-based dentistry; Implementation; Population health; Public health.
