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.
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
A dermatome is used
1. To remove scar tissue
2. To harvest skin grafts
3. To abrade skin which is pigmented
4. For pairing of lacerated soft tissue
Oral Surgery
Answer: 2
A dermatome is used to harvest skin grafts.
The following is least toxic of all local anaesthetics
1. Tetracaine
2. Mepivacaine
3. Prilocaine
4. 2-Chloroprocaine
Oral Surgery
Answer: 4
The following is least toxic of all local anaesthetics: 2-Chloroprocaine.
Which of the following is preferred local anaesthetic technique for haemophilics
1. Nerve block
2. Supraperiosteal
3. Intraligamentary
4. Field block
Oral Surgery
Answer: 3
Intraligamentary anaesthesia is the preferred local anaesthetic technique for haemophilics.
After the surgical removal of chronically infected teeth in a controlled diabetic patient, which of the following is of utmost importance
1) Postoperative check of patient for bleeding
2) Revaluation of insulin dosage being taken by the patient
3) Both the above
4) None of the above
Oral Surgery
Answer: 2
Diabetes affects wound healing and immune response. After surgery, stress and altered eating patterns can impact blood glucose levels. Monitoring and adjusting the insulin dosage as necessary is critical to prevent complications such as infection or delayed healing. Postoperative bleeding is important but secondary to glycemic control in diabetics.
Of the following which tooth is most difficult to anaesthetize by infiltration technique alone
1. Maxillary canine
2. Macillary central incisors
3. Maxillary first molar
4. Maxillary first premolar
Oral Surgery
Answer: 3
Of the following, the maxillary first molar is the most difficult to anaesthetize by infiltration technique alone.
Open reduction and internal fixation of fracture fragments in the older patients is risky because
1) Of their old age, they less likely tolerate the major procedure under general anaesthesia
2) Fixation is difficult because bone will become more dense as age advances
3) Both of the above are correct
4) None of the above are correct
Oral Surgery
Answer: 4
The risk associated with open reduction and internal fixation (ORIF) in older patients is not solely due to their age or increased bone density. It's important to consider their overall health, including potential comorbidities and reduced healing capacity. The risks might be higher due to factors like poor bone quality, increased surgical time, and the potential for complications such as infection and nonunion.
