, Q1. In a patient with a severely resorbed mandibular ridge, which radiographic
finding would most contraindicate the use of a conventional complete denture and
necessitate an implant-supported prosthesis?
A. Mental foramen located superiorly, near the crest of the ridge
B. Adequate attached mucosa with minimal undercuts
C. Moderate bone height with a U-shaped arch form
D. Class III ridge resorption with a flat, atrophic ridge
Correct Answer: A. Mental foramen located superiorly, near the crest of the ridge
Rationale: A superiorly positioned mental foramen near the crest places the
neurovascular bundle at high risk of compression and paresthesia under a conventional
denture base. This finding is a strong indicator for an implant-supported prosthesis to
avoid nerve impingement. The other options describe conditions that are more favorable
for conventional denture therapy.
Why Wrong:
B - Adequate attached mucosa and minimal undercuts are favorable for conventional
denture retention.
C - A U-shaped arch form with moderate bone height is generally suitable for a
conventional denture.
D - Class III resorption is challenging but does not specifically contraindicate
conventional dentures; the mental foramen position is the critical factor.

13th Ed., Ch. 5.
Q2. A denture base exhibits a 'crazed' surface after repeated disinfection with a
chemical agent. Which monomer system and disinfection protocol is most likely
responsible for this surface degradation?
A. High-impact acrylic resin with 2% glutaraldehyde immersion for 10 minutes
B. Heat-polymerized PMMA with 1% sodium hypochlorite soak for 15 minutes
C. Microwave-polymerized resin with 0.5% chlorhexidine spray
D. Light-activated urethane dimethacrylate with 70% isopropyl alcohol wipe
Correct Answer: B. Heat-polymerized PMMA with 1% sodium hypochlorite soak for
15 minutes
Rationale: Sodium hypochlorite in concentrations above 0.5% is known to cause surface
crazing and whitening of PMMA denture bases, especially with prolonged exposure.
Heat-polymerized PMMA is susceptible to oxidative degradation by hypochlorite.
Glutaraldehyde is generally safe for acrylic, chlorhexidine is mild, and isopropyl alcohol
can soften some resins but is less commonly associated with crazing in urethane
dimethacrylate.
