INTRODUCTION Periodontal disease is multi-factorial with
microbial dental plaque as a initiator .
However the manifestation , progression of periodontal disease and treatment outcome is influenced by wide variety of determinants.
my seminar attempts to provide an overview of different risk factors & their methods of assesment.

Risk
Its defined as probability that an event will occur in the future (or) the probability that an individual develops given disease (or)experience a change in health status during a specified interval of time .
Kleinbaum D 1982

Periodontal risk group
Its defined as subgroup (of a larger population) whose members on an average have a higher probability of developing periodontitis/and or loss of periodontal support with in a given time period then the remaining population

DISEASE A condition of the body or some part/organ of
the body in which its function are disrupted/deranged
MEASURES OF EXPRESSING HEALTH RISK Among the main measures used to express ,
health risk are absolute risk, relative risk, odds ratio , & attributable risk
![Page 7: Clinical Risk Assesment - Dr Harshavardhan Patwal](https://reader035.fdocuments.us/reader035/viewer/2022062904/587ab5981a28abc0478b4605/html5/thumbnails/7.jpg)
ABSOLUTE RISK It’s the probability that an individual will
develop the disease over a specific period of time
Relative risk It’s a comparison of the health risk between
two population. This measure is common place in prospective and cohort studies and is assessed as ratio of the disease incidence in these population .
A higher relative risk in these types of studies is often used to suggest a strong evidence for causation of the out come measure.
Can be measured only when the outcome is dichotomous.

HEXAGONAL RISK DIAGRAM Lang and Tonetti in 2003 described a functional
diagram based on six parameters for use in estimating an individual risk for progression of periodontitis
The PRA model consists of an assessment level of infection, the prevalence of residual pockets, tooth loss, an estimation of loss of periodontal support in relation to patients age, an evaluation of systemic and genetic conditions and an evaluation of the environmental/behavioural factor smoking
All parameters have their own scale for low, moderate and high risk profiles

CONTINOUS MULTILEVEL RISK ASSESSMENT
The risk assessment models uses retrospective and current data to assess the risk and is based on the simple scale of 0-5
A functional diagram was developed depending on the area of the polygon it categorizes to low, medium, high risk categoriesSandhya and Sripriya in 2011

Conclusion
“ Measurement, Assessment, Elimination or reducing as many risks as possible will improve disease prevention and treatment outcomes”
