Evidence Based Dentistry

What is Evidence Based Dentistry?

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."
