Abstract
The purpose of this article was to highlight the recent call for an evidence-based approach to public policy decision making with respect to funding dental services and the need this creates for enhanced clinical research activities. Systematic reviews on topics of importance to oral health care practitioners are being conducted and published by various national and international groups. Recent activities to assess evidence to support medically necessary dental services were reviewed. An Institute of Medicine Committee on Medicare Coverage Extensions found little published scientific evidence that directly assessed the effectiveness of dental services in preventing or managing systemic health outcomes for patients with head and neck cancer, lymphoma, leukemia, organ transplantation, and heart valve repair or replacement. The scientific community must strive to meet the challenge of conducting well-designed randomized, controlled trials that test the impact of dental treatment interventions on systemic health to meet the growing need for evidence to support or refute widely accepted dental treatment protocols for medically complex patients.
