Evidence-Based Dentistry

The American Dental Association’s Center for Evidence-Based Dentistry defines evidence-based dentistry (EBD) as “an approach to oral healthcare 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”.

American Dental Association (ADA): Center for Evidence-Based Dentistry
The ADA Center for Evidence-Based Dentistry “facilitates access to the best available scientific information related to oral health care, and develops evidence-based resources for use in clinical practice.” Its website features more than 1,300 systematic reviews, as well as clinical recommendations, and links to organizations, journals, databases, and tutorials on evidence-based dentistry.

Evidence-Based Dentistry
Developed at the Health Sciences Library, University of North Carolina–Chapel Hill, this evidence-based dentistry site explains what evidence-based dentistry is, addressing levels of evidence, study types, and the critical appraisal process. In addition, PubMed Clinical Queries and the Cochrane Collaboration are each discussed in detail. A bibliography is provided.

Evidence-Based Dentistry Tutorial
From the Information Services Department, Library of the Health Sciences, University of Illinois–Chicago, this tutorial consists of five modules: introduction to evidence-based dentistry, structure of literature, research design, searching of the literature, and evaluation of the quality of research. The tutorial can be followed sequentially or by module of interest. Also included is a glossary of terms.

Evidence-based Endodontics Literature Database
Faculty at the School of Dentistry, University of Detroit Mercy, developed the Evidence-based Endodontics Literature Database to provide an “educational evidence tool to help justify historical and current endodontic treatment decisions.” Articles are selected from readings lists of endodontic programs in the United States, textbooks, and PubMed topical searches. Articles are categorized by subject and evidence-based ranking.

EviDents Search Engine for Evidence-based Dentistry
EviDents assists in the construction of evidence-based clinical questions in PubMed. Users can enter terms for the four PICO elements (problem, intervention, comparison, outcome), identify a specific clinical area (e.g., periodontics, orthodontics, implants, caries), and select other characteristics to apply to the results.

National Guideline Clearinghouse
The National Guideline Clearinghouse (NGC), an initiative of the Agency for Healthcare Research and Quality, US Department of Health and Human Services, is a public resource for evidence-based clinical practice guidelines. NGC contains structured abstracts and links to full text. A Guideline Comparison tool allows side-by-side comparisons. Oral health guidelines are listed under Stomatognathic Diseases in the Disease/Condition section.

National Health Service (NHS) Evidence: Oral Health
From the United Kingdom, NHS Evidence: Oral Health provides access to evidence-based reports, presentations, annual evidence updates for hot topics, and dentistry-related news items. Material is categorized by subject, with results listed under five headings: Guidance Pathways, Evidence, Reference, Education, and Patient Information.

Oral Health Group
The Cochrane Collaboration’s Oral Health Group produces reviews and protocols for the Cochrane Database of Systematic Reviews. The Links section lists evidence-based dentistry and oral health journals, databases, and dental associations.

TRIP Database
The TRIP Database is a clinical search tool designed to allow health professionals to rapidly identify the highest quality clinical evidence for clinical practice. TRIP allows simultaneous searching of multiple evidence-based resources. Registration is free and allows users to create profiles to search oral health terms or conditions automatically. Features include a PICO-style search wizard and a semantic search for related articles.
