Transcript of Oral and Dental Research - Getting started

The diversity of oral and dental research and its translation into the clinical setting

Research Questions
Enamel Defects
Active or Arrested?
Restorative materials
Porcelain, composite, amalgam, gold
Success or failure
Gum disease
Calculus, gingivitis, oral health
Gingivitis progression to periodontitis
which is best?
You see a problem and have a question
You are curious and ask more questions

Why did it occur?
What caused it?
What happens if I intervene?

Where are the answers?
Caries reduction since 1998 - 54% to 31%
People with decay have 2.7 teeth affected

Crowns up from 34 to 37%

Healthy periodontal status only 17%

Negative effects on life due to poor oral health
frequently 16%
severely 17%

Significant health inequalities
Some Headlines
Oral Health
5% of Health expenditure
16% of private health care expenditure

EU spend € 79 billion likely to increase to €93 billion in 2020

Mouth most expensive part of body to treat
Will start to exceed cancer, heart disease, stroke and dementia

Strong evidence that benefits of prevention exceed costs of treatment
Why do Research?
Will vary
Personal standing/status
Contribution to knowledge

Institutional requirement
Rewards/ Salary and Job Security

Enjoy the challenge

Planning your Research
First think of a problem that needs researching
Then discuss how you would do this with your colleague
Clinical Research
Pros Laboratory
Pros Clinical
Cons Clinical
Cons Laboratory
Undertake Literature review
Your working hypothesis
Identify your research problem
Design of study
Methods you will use
Materials you will need
Analysis of data
Results obtained
Data collection
Interpreting results
Link to literature review
Write it up, publish

Tell people about it
Lets think about a research topic
Own practice environment
not audit related

Take home messages

Oral cancer is on the increase
High mortality, 5 year survival less than 50% for several sites
Dentists important in early detection of suspicious lesions
Any ideas for research
