Nerve membrane stabilization action of local anaesthetic agents is due to
1. Increasing conductance of potassium ions
2. Creating negative after potentials
3. Preventing conductance of Na ions from the exterior of the nerve to the intrior
4. None of the above
Oral Surgery
Answer: 3
Nerve membrane stabilization action of local anaesthetic agents is due to preventing conductance of Na ions from the exterior of the nerve to the interior.

Which of the following is not an advantage of marsupialisation
1) Exposure of very little bone
2) Preservating of vital structure
3) Rapid healing
4) Conserve surgical structures
Oral Surgery
Answer: 3
Marsupialization is a surgical procedure often used for cysts or abscesses. While it does have several advantages, such as minimal exposure of bone and preservation of vital structures, it is not typically associated with rapid healing. The healing process can be prolonged compared to other surgical techniques because it involves creating a permanent opening for drainage, which may take time to close completely.
"Ash forceps" is commonly used for
1. Extraction of lower incisor
2. Extraction of upper canines
3. Holding tissues prior to biopsy
4. Holding vascular areas during surgery
Ash forceps are commonly used for extraction of lower incisor.
The blood product of choice for treatment of haemophilics is
1. Fresh blood
2. Cryoprecipitate
3. Fresh frozen plasma
4. Plasma
Oral Surgery
Answer: 2
Cryoprecipitate is the blood product of choice for treatment of haemophilics, as
it is rich in Factor VIII, which is deficient in this condition. It is used to
control bleeding during surgical procedures.
