The American Dental Association defines evidence based dentistry as:
"an approach to oral health care that requires the judicious integration of systematic assessments of clinically relevant scientific evidence, relating to the patient's oral and medical condition and history, with the dentist's clinical expertise and the patient's treatment needs and preferences."
This series of short commentary articles from the Journal of the American Dental Association (JADA) gives an excellent explanation of Evidence-Based Dentistry in practice as well as an overview of how to engage in it.
