An evidence-based approach to clinical practice guidelines in periodontics

The use of clinical practice guidelines has received considerable attention in medicine and dentistry for improving clinical decision making and cost-effective care. Leaders in dentistry are increasingly calling for improved standardization of treatment through the development of clinical practice guidelines based on empiric clinical evidence. Guidelines have been shown to minimize treatment variability and ensure the quality and cost-effectiveness of care. Other potential applications include educating individuals or groups; development of quality indicators; improved allocation of resources such as insurance payment decisions; and reduced risk of liability for negligent care. Recently, a series of evidence-based clinical algorithms and practice guidelines were developed for regenerative periodontal treatment. Such guidelines have the potential to improve outcomes of periodontal care for providers, patients, and other interested parties. This review discusses the rationale for guideline development and the role of clinical practice guidelines in the area of periodontal decision making and provision of care.
