TheEvidence Database Topic Index in the American Dental Association's Center for Evidence-Based Dentistry provides access to a curated collection of current systematic reviews, critical summaries and practice guidelines.
The Evidence Database is updated quarterly so it is possible that you will find a more current review if you search a continuously updated database like PubMed.
You should also turn to a database like PubMed when you do not find a review on your topic in the ADA's DSR. Search first for a systematic review and then for individual research studies.
The Cochrane Collaboration is an international, non-profit, independent organization that publishes systematic assessments of evidence of the effects of healthcare interventions. Cochrane systematic review authors follow a published procedure that has become the gold standard for systematic reviews of interventions.
This worksheet is to be used to guide a searcher through: using PICO to clearly articulate a clinical question of interest; using the parts of the clinical question to create and then revise a PubMed search; selecting an article based on the evidence hierarchy; and linking to tools to use to critically appraise the selected article(s).
This worksheet demonstrates: using PICO to clearly articulate a sample clinical question; constructing and revising a PubMed search; selecting an article based on the evidence hierarchy. It links to a tool to use in critically appraising the selected article.
