Question

which chronic disease may be prevented by regular visits to the dentist?

a. oral cancer

b. allergies

c. emphysema

d. obesity

Explanation:

Oral cancer is a disease affecting the oral cavity, and dentists can detect early signs during regular check - ups. Allergies involve the immune system reacting to allergens, emphysema is a lung - related disease, and obesity is related to body weight and metabolism. None of these (allergies, emphysema, obesity) are directly related to dental check - ups for prevention. So the chronic disease that can be prevented by regular dentist visits is oral cancer.

Answer:

A. Oral cancer
