The American Dental Association's Center for Evidence-Based Dentistry: a critical resource for 21st century dental practice.

Through its website (http:// www.ada.org/prof/resources/ebd/index.asp), the American Dental Association's Center for Evidence-Based Dentistry offers dental health professionals access to systematic reviews of oral health-related research findings, as well as Clinical Recommendations, which summarize large bodies of scientific evidence in the form of practice recommendations, e.g., the use of professionally-applied topical fluoride and pit-and-fissure sealants. Another feature of the site of great practical importance to the practicing dentist is the Critical Summary, which is a concise review of an individual systematic review's methodology and findings, as well as the importance and context of the outcomes, and the strengths and weaknesses of the systematic review and its implications for dental practice.
