Correct Answer: A, B
2. Which factors influence the stability of a complete denture?
A. Ridge morphology
B. Saliva quantity and quality
C. Patient age
D. Denture base adaptation
,Rationale: Stability depends on anatomical features (ridge
shape), saliva, and how well the denture base fits. Age alone
does not directly affect stability.
Correct Answer: A, B, D
3. What are common causes of denture stomatitis?
A. Poor oral hygiene
B. Ill-fitting dentures
C. Candida infection
D. Vitamin D deficiency

8. Which instruments are used to take preliminary
impressions?
A. Stock trays
B. Alginate
C. Custom trays
