1.The fracture of the tooth bearing sement of the mandible is;

A. Simple
B. Complex
C. Compound
D. Comminuted

Answer C
COMPOUND FRACTURE

• A fracture in which an external wound involving the skin, mucosa, or periodontal membrane communicates with the break in the bone.

2. The proximal segment of mandibular angle fracture is usually displaced in which direction;

A. Anterior and superior
B. Posterior and interior
C. Interior only
D. Posterior and superior

Answer A
Loss of the mandibular angle on palpation may be because of an unfavorable angle fracture in which the proximal segment rotates superiorly. The anterior face may be displaced forward, causing elongation. Lacerations, hematoma, and ecchymosis may be associated with mandibular fractures.

3. In cases of subcondylar fracture, the condyle moves in;

A. Anterior lateral direction
B. Posterior medial direction
C. Posterior lateral direction
D. Anterior medial direction

Answer A

4. A fracture of the mandible in the canine region in a 6 year old child should be managed by;

A. Cap splint fixation
B. Intermaxillary fixation
C. Risdon wiring
D. Transosseous wiring

Answer A
Minimally displaced fractures can be managed conservatively by the modified closed cap splint compared to the severely displaced fracture which may require open reduction and rigid internal fixation. In pediatric patients cap splint can be recommended in mandibular symphysis/ parasymphysis fractures.

5.  A fractured mandible should be immobilized for an average of

A. 3 weeks
B. 6 weeks
C. 9 weeks
D. 12 weeks

Answer: B
Closed reduction and OR/IF using wire osteosynthesis require an average of 6 weeks of immobilization by MMF in order to achieve satisfactory healing

6. Primary healing of a mandibulat fracture is seen following fixation with;

A. Gunning splints
B. Compression plates
C. Trans-osseous wires
D. Clampy plates

Answer B
Fixation of the fractured bone with rigid mechanical constructs, such as by compression plates or lag screw fixation supported with neutralization plates, creates this stability. These constructs of rigid internal fixation result in minimal interfragmentary strain.

7. Eburnation is seen in ;

A. Malunion
B. Non union
C. Osteomyelitis
D. Osteoradionecrosis

Answer B
Eburnation describes a degenerative process of bone commonly found in patients with osteoarthritis or non-union of fractures. Friction in the joint causes the reactive conversion of the sub-chondral bone to an ivory-like surface at the site of the cartilage erosion.

8. Lower lip parasthesia occurs in;

A. Body fracture
B. Symphysis fracture
C. Coronoid fracture
D. Condyle fracture

Answer A

9. Green stick fracture is most common with;

A.older people
B. Adult
C. Children
D. Soldiers

Answer C
GREENSTICK FRACTURE

1. 1. A fracture in which one cortex of the bone is broken, the other cortex been bent.
   2. SEEN IN CHILDREN

10. The treatment for a mandibular fracture between the incisors is;

A. Risdon wiring
B. Essig wiring
C. Cap splint with circum-mandibukar wiring
D. Transosseous wiring

Answer A
