MDS PREP
A surgical procedure required bilateral block. A bilateral inferior alveolar nerve block is�
�1. Not contraindicated
�2. Should rarely be preformed
�3. May cause space infection
�4. None of the above
Oral Surgery
Answer: 1
A bilateral inferior alveolar nerve block is not inherently contraindicated. It
is commonly performed in cases requiring surgery on both sides of the mandible.
However, it should be done with caution in patients with certain medical
conditions or anatomical variations that could increase the risk of
complications. It is important to assess each patient individually before
administering the block.
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.
Frequently which of the following constitutes is amide type local anaesthesia causes allergic reaction
1. Lignocaine hydrochloride
2. Methyl paraben
3. Adrenaline
4. Contaminants in the solution
Oral Surgery
Answer: 2
Methyl paraben frequently causes allergic reactions in amide type local anaesthesia.
Patients with end-stage renal disease are of increased risk when undergoing extraction of teeth because they�
�1. Have an increased tendency to bleed
�2. Are susceptible to infections
�3. Are often on steroid therapy
�4. All of the above
Oral Surgery
Answer: 4
Patients with end-stage renal disease are at increased risk during tooth
extraction due to several factors. They often have an increased tendency to
bleed due to platelet dysfunction and are susceptible to infections due to
compromised immunity. Additionally, they are often on steroid therapy, which can
affect wound healing and increase the risk of infection.
Gillies approach for reduction of zygomatic fractures is done through�
�1. Temporal fossa
�2. Infra temporal fossa
�3. Infra orbital fossa
�4. All of the above
Oral Surgery
Answer: 1
The temporal fossa is located on the side of the skull, above the zygomatic arch and lateral to the orbit. The Gillies approach involves an incision in the temporal region to access the zygomatic bone, which is then manipulated to reduce the fracture and restore its normal anatomical position. This approach is commonly used in oral and maxillofacial surgery for the management of complex zygomatic fractures.
Rongeur is commonly used to
1. Cut the bone
2. Extract third molars
3. Place the sutures in the areas where access is limited
4. None of the above
Oral Surgery
Answer: 1
Rongeur is commonly used to cut the bone.
For extraction of mandibular molar, anaesthesia is given to act on
1. Inferior alveolar nerve
2. Buccal nerve
3. Lingual nerve
4. Masseteric nerve
Oral Surgery
Answer: 1
For extraction of mandibular molar, anaesthesia is given to act on the inferior alveolar nerve.
In a 19-years-old patient with a swelling over the left angle of the mandible, temperature of 38 degree celcius and negative history of trauma, one should suspect
1) Spontaneous fracture of the mandible
2) Pericoronal infection
3) Mumps
4) Sjorgen"s syndrome
Oral Surgery
Answer: 2
Explanation:In this scenario, the presence of swelling and fever in a young adult, particularly in the area of the mandible, suggests a pericoronal infection, which is often associated with the eruption of third molars (wisdom teeth). The lack of trauma further supports this diagnosis, as pericoronal infections are common in the absence of direct injury.
