What Kind Of Question Are You Asking?
Background information
General questions (cause, presentation, treatment)
Foreground information
Specific questions regarding a patient (original
research, secondary sources)
Where do you find background information? Where do you find foreground information?
-
8/8/2019 Evidence Based Dentistry UAB School of Dentistry Fall 2010
11/49
Background Information = Textbooks
You have limited knowledge on the topic
Common facts or background information
Facts that remain relatively static over timesuch as:
the diagnosis of periodontal (gum) diseases
how to perform a oral exam
characteristics of TMD/TMJ (TemporomandibularDisorders)
anatomy, physiology, descriptive pathology

13/49
Foreground Info = Journal
You know a little about the topic, but need
specific information about how to manage a
patient with a disorder
Journals
Some are peer reviewed, some are not
Useful for finding new therapies, diagnoses, etc.
Requires a good PICO question!

Why Is This Needed?
Dental research is continuous
Implementation of findings is delayed
Dentists must stay current
Evidence-based practice has been shown to
keep dentists up-to-date
