INFORMATION RESOURCE

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?


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


12/49

WHERE DO I FIND THEM?

Where to find online textbooks:

Library Catalog

http://catalog.lhl.uab.edu

Basic Medical Book Collections online:

Access Medicine

MD Consult http://www.uab.edu/lister/databases


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!

What is a systematic review?

treatment for a specific disease or other problem in

health care

Identifies and includes all up-to-date and relevantstudies and trials

Determines whether or not the intervention or

treatment works

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
