What is the effect of vitamin E deficiency on cell membranes?
1) Increased fluidity
2) Decreased fluidity
3) No change in fluidity
4) Unknown
Physiology
Answer: 2
Vitamin E is an important antioxidant that protects unsaturated fats in cell membranes from oxidation. Without vitamin E, these fats can become oxidized, leading to decreased fluidity and altered function of membranes.

Forces acting on the abutment tooth in an FPD can be effectively minimised by
1) Directing the forces perpendicular to long axis of the crown
2) Directing the forces along the long axis of the crown
3) Both of the above
4) None of the above
Prosthodontics
Answer: 2
Directing forces along the long axis of the crown is an effective way to minimize the stresses on an abutment tooth in a fixed partial denture (FPD). This allows the tooth to function more naturally and reduces the likelihood of complications such as root fracture or periodontal damage
