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.
The following anatomical landmarks are useful in the closed mouth approach of mandubular nerve block except
1. Occlusal plane of occluding teeth
2. Anterior border of ramus
3. Mucogingival junction of the mandibular teeth
4. A & B
Oral Surgery
Answer: 3
The closed mouth approach of mandibular nerve block relies on the anatomical
landmarks of the occlusal plane of occluding teeth and the anterior border of
the ramus. The mucogingival junction is not a relevant landmark for this
technique.
The addition of hyaluronidase to a local anaesthetic solution might
1. Increase the duration of anaesthesia
2. Limit the area of anaesthesia
3. Reduce bleeding
4. Enhance diffusion of local anaesthetic
Oral Surgery
Answer: 4
The addition of hyaluronidase to a local anaesthetic solution might enhance diffusion of local anaesthetic.

1. Nerve block
2. Supraperiosteal
3. Intraligamentary
4. Field block
Oral Surgery
Answer: 3
Intraligamentary anaesthesia is the preferred local anaesthetic technique for haemophilics.
Compbell line is seen in
1) Transpharyngeal view
2) Transorbital view
3) Occipitomental view
4) Towne view
Oral Surgery
Answer: 3
The Campbell line is an important anatomical reference line
used in radiology, particularly in the context of the occipitomental
view (also known as the Water's view). This line is drawn from the
outer canthus of the eye to the midpoint of the maxillary sinus and is used to
assess the position of the maxillary sinuses and other related structures in the
skull.
Occipitomental view: This view is commonly used in
maxillofacial imaging to visualize the maxillary sinuses, orbits, and nasal
cavity. The Campbell line helps in evaluating the relationship of these
structures.
Transpharyngeal view: This view is used to visualize the
pharynx
Transorbital view: This view focuses on the orbits and
surrounding structures
Towne view: This view is used to visualize the occipital
bone and the base of the skull
The scalpel blade most commonly used for oral surfical procedures is
1. No. 22
2. No. 12
3. No. 11
4. No. 15
Oral Surgery
Answer: 4
The scalpel blade most commonly used for oral surgical procedures is No. 15.
Hypoglycaemia may occur in a patient taking insulin and undergoing extraction when
1. Extraction is done on empty stomach
2. Patient had an infection
3. Patient had no exercise in the morning
4. None of the above
Oral Surgery
Answer: 1
Hypoglycaemia may occur in a patient taking insulin and undergoing extraction
when the procedure is done on an empty stomach. This is because insulin lowers
blood sugar levels, and without food to balance the insulin's effect, the
patient could experience a dangerous drop in blood glucose. It is important to
ensure that the patient eats before the surgery and that glucose levels are
monitored.
