DOH321 Research Skills Guide: Evidence-Based Practice (EBP)


When searching for information in the field of dentistry to answer clinical or research questions, you may be required to locate evidence-based practice resources. The information below and on the following page provide an introduction to the Evidence Based Practice concept.

What is Evidence-Based Practice?

Evidence Based Practice was first defined by Dr David Sackett in the 1990s, but a more recent definition has it as

“integrating the best available research evidence with clinical expertise and the patient’s unique values and circumstances” (Straus, Glasziou, Richardson, & Haynes, 2011).

And "it also requires the health professional to take into account characteristics of the practice context in which they work" (Hoffman, Bennett, & Mar, 2016, p. 4).

  • Evidence-based practice is the intersection of clinical expertise, research evidence, information from the practice context, and the patients values and circumstancesThe best research evidence is usually from relevant research that has been carried out using sound methodology.
  • Clinical expertise is a combination of the clinician’s experience, education and clinical skills.
  • The patient has his/her own personal preferences, concerns, expectations, and values.
  • The practice context includes characteristics of the situation in which the interaction between patient and health professional is taking place - for example, the resources available.



Evidence-Based Practice has been expanded from Evidence-Based Medicine to apply to other health professions including Dentistry.

The Steps in EBP

There are various ways of listing the steps in the Evidence-Based Practice process, but a common way has 5 main steps:

1 Expressing the problem as a clinical question (Ask the question)
2 Finding evidence-based resources that answer the question (Acquire the evidence)
3 Critically appraising the evidence to assess its validity (Appraise the evidence)
4 Applying the evidence (Apply the evidence)
5 Re-evaluating the evidence and its application (Re-evaluate the evidence)
