Finding good information resources can be frustrating!
Make it a more satisfying experience by using these strategies:
Use specific search terms - A search for global warming will get thousands of results, but global warming and agricultural impact will result in fewer and more relevant results.
Try using the "Advanced Search" screen - You'll find it easier to add more terms to your search and specify where they should appear - for example, in an article title or subject heading.
Try an exact phrase - Searching for stem cell research will retrieve results with these three words, but to ensure that they appear as a phrase (together and in the same order), try putting them in quotation marks: "stem cell research".
Use "search options" or "limits" - limit your search to full text articles, academic/scholarly articles (what's this?) or to a specific date range. Limit features can often be found in a side menu or on the database's Advanced Search screen.
If you get stuck, contact your campus librarian!
Using the PICO method can help you form research questions more efficiently. PICO stands for:
P - Patient, Population, or Problem
I - Intervention
C - Comparison
O - Outcome
A sample question would be, in adults with periodontitis (P) what is the effect of manually flossing (I) compared to using interdental aids (C) on gingivitis scores (O)?
Your instructor may require articles from scholarly journals (also called academic or peer-reviewed journals) instead of popular magazines.
There's also something called a trade journal.
What's the difference? Here's a quick overview courtesy of Ithaca College Library.
When researching Dental Hygiene topics, try some of the following databases for the most valuable information.
According to the American Dental Association, evidence based practice is “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.”
There are four steps in applying evidence-based research:
1. Ask a clinical question in a PICO format (see sidebar for PICO definition).
2. Aquire the evidence.
3. Appraise the evidence (the evidence based pyramid above can help).
4. Apply the evidence to clinical practice.
