Epidemiology of Periodontal Disease

The lecture covers the epidemiology of periodontal disease, focusing on risk factors, prevalence, and theories of disease progression. It discusses the role of epidemiologists in identifying risk factors and how these can lead to treatment standards. The lecture also explains the prevalence of periodontal disease, the variables affecting it, and the indices used for evaluation. Various theories on disease progression are explored, highlighting the complexity of periodontal disease and its impact on adults.

What is the primary focus of epidemiology in the context of periodontal disease?

• Studying individual cases of disease

• Understanding health and disease in the total population

• Developing new dental treatments

• Analyzing the economic impact of dental care

Which of the following is NOT considered a risk factor for periodontal disease?

• Heredity

• Gender

• Socioeconomic status

• Dietary preferences

How is disease prevalence defined?

• The number of new cases in a given time period

• The total number of cases, both old and new, at a specific time

• The rate of disease spread in a population

• The number of cases that result in death

Which index is commonly used to measure periodontal disease?

• RBC

• BMI

• CPITN

• IQ

Which demographic is more likely to experience severe periodontal disease?

• Individuals with higher education

• Children under 10

• Males

• Females

What is a common barrier to accessing dental care?

• Lack of interest

• Transportation issues

• Excessive dental clinics

• Over-the-counter treatments

Why is it more challenging to evaluate periodontal disease compared to caries?

• Periodontal disease involves both hard and soft tissues

• Caries require more complex diagnostic tools

• Caries are less common

• Periodontal disease involves only the tooth structure

What is a leading cause of tooth loss in adults over 45?

• Caries

• Periodontal disease

• Oral cancer

• Tooth fractures

Which theory suggests that periodontal disease progresses at a slow and constant rate?

• Random burst theory

• Continuous Progressive theory

• Host bacterial interaction theory

• Non-specific plaque theory

What does the asynchronous multiple burst theory propose?

• Disease activity is predictable

• Multiple bursts of activity followed by remission

• Disease activity is constant

• Disease activity occurs in a single burst
