what is evidence based dentistry?
3-part harmony, all optimize treatment outcomes
what are the three parts to evidence based dentistry?
best evidence
clinical judgement
patient values
best evidence
evaluation of the best available scientific evidence
clinical judgement
recognition of your own clinical expertise
patient values
understanding patients needs and preferences
why would you not use EBD?
Not simply just reporting the findings of the study or considering just one
study. It seeks to evaluate all scientific evidence on a specific topic. This allows us to broaden our treatment options by using more current evidence.
The steps in developing an evidence based approach to practice is:
- Determining your clinical question (What do you want to know?)
the hierarchy of evidence is based on the ability to
control for bias and demonstrate cause and effect in humans
hierarchy of evidence from top to bottom (7)
meta analysis systematic review randomized controlled trial cohort studies case control studies case series/case report animal studies
types of questions patients ask (6)
prevalence etiology/risk diagnosis therapy prognosis phenomena
prevalence
what is the frequency?
etiology/risk
what causes the problem?
cohort study>case control>case series
diagnosis
does the person have it?
prospective, blind comparison to a gold standard (RCT) or cross-sectional
therapy
what is the best treatment?
randomized control study> cohort study
prognosis
who will get the problem? (group of linked individuals)
cohort study>case control>case series
phenomena
what are the concerns?

doctor uses given info to search for best evidence to answer the question, critically appraising the evidence and applying results in
clinical practice
what key words do you use when searching in pubmed?
PICO keywords
what order do you write your questions?
PICO
in patients with…will…as compared to…result in…
when searching for evidence, what order do you use?
I, C, P, O
what are common barriers to rational decision making?
