The statement that the average child will develop a new carious lesion between ages 6 and 10 represents which measure?

• A. Incidence
• B. Prevalence
• C. Mortality
• D. Morbidity

Answer: (A)

Incidence. This describes new cases appearing in a defined time period. Saying that the average child will develop a new carious lesion between ages 6 and 10 refers to lesions that are newly diagnosed during that age interval, not to all existing cases at a point in time. Prevalence would count all cases present at a specific moment, including longstanding ones. Mortality is about deaths, and morbidity describes disease impact or burden, not the rate of new cases.
