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.

2. At the junction of clinical and anatomical crowns
3. Near junction of apical and middle thirds of clinical crown
4. On the root surface as far apically as possible
Oral Surgery
Answer: 4
The tips of anatomic forceps should be placed on the root surface as far apically as possible.
One wants to anaesthetise the inferior alveolar nerve at the point at which it exits from the mandibular canal, so the injection site most often located in
1) Between first and second molars inferior to the root apices
2) Between first and second molar superior to root apices
3) Between first and second premolars inferior to root apices
4) Between first and second premolars superior to root apices
Oral Surgery
Answer: 3
The inferior alveolar nerve block (IANB) is a common technique used in dentistry to anesthetize the mandibular teeth, including the molars. The nerve exits the mandibular foramen and runs along the mandibular canal before it branches into the incisive and mental nerves. For effective anesthesia, the injection site is typically located between the first and second premolars, aiming towards the medial surface of the ramus of the mandible, and the needle is inserted until it is just inferior to the root apices of these teeth. This position allows the anesthetic solution to reach the nerve as it emerges from the bone and before it gives off its major branches, thus achieving profound anesthesia for the procedure.
The elevators that employ both the lever and wedge principles during extraction of root tip are
1. Pott"s elevators and apex elevators
2. Apex elevators and straight elevator
3. Straight elevators and Pott"s elevators
4. Pott"s elevators and Cryer elevators
Oral Surgery
Answer: 2
The elevators that employ both the lever and wedge principles during extraction of root tip are apex elevators and straight elevator.
In dislocation of the jaw, displacement of the articular disc beyond the articular tubercle of the temporomandibular joint results from spasm or excessive contraction of the following muscle
1. Buccinator
2. Lateral pterygoid
3. Masseter
4. Temporalis
Oral Surgery
Answer: 2
In dislocation of the jaw, displacement of the articular disc beyond the articular tubercle of the temporomandibular joint results from spasm or excessive contraction of the lateral pterygoid muscle.

1. 100 mg
2. 30 mg
3. 500 mg
4. 700 mg
Maximum recommended dosage of lignocaine with 1:1,00,000 adrenaline subcutaneously is 100 mg.

3. Figure of "eight" motion
4. None of the above
Oral Surgery
Answer: 1
To luxate a tooth with forceps, the movements should be firm and deliberate primarily to the facial surface with secondary movements to the lingual surface.
