This document contains a quiz on dental extraction techniques and procedures. It covers topics like the proper use of dental elevators, criteria for surgical extractions, preoperative radiographs, application of correct force magnitude and direction to avoid complications, advantages of different elevator types, debridement after extraction, when to use straight elevators for luxating lower third molars based on root curvature and neighboring tooth positions, and advantages of suturing wounds after extraction like decreasing infection, pain and promoting rapid healing.

1. 5th
year exam
1-The correct use of dental elevators needs
a- Correct grip
b- Point of application
c- Proper fulcrum
d- Force magnitude& DIRECTION
e- All of the above
2-Surgical extraction needs
a-A mucoperiosteal flap
b-decrease resistance of bone &tooth or both
c-Correct application of force magnitude &direction
d-All of the above
3- A correct mucoperiosteal flap must include these criteria except
a-broad base
b-proper extension
c-includes both mucosa &periostium
d-short extension
4-Preoperative radiographs are essential before surgical extraction for the following except
a-relation to vital structures
b-number of roots
c-curvature of roots
d-presence of pathological lesions
e-any systemic disease of the patient

2. 5-Applicaton of force of unknown magnitude and direction can lead to:
a-fracture of the tooth
b-fracture of the jaw
c-breakage of the elevator
d-All of the above
6- Cryer elevator is preferred than cross bar elevator because of:
a-less force magnitude
b-less fracture of the jaw
c-more controlled force
7- Debridement of the wound includes
a-removal of tooth debris
b-removal of any parts of fillings
c-removal of detached bone fragments
d-All of the above
8-The straight elevator is used to primarily luxate the lower third molar if:
a-the roots are distally curved
b-the second molar is present-
c-the first molar is missing &the second molar is to be extracted
d-All of the above
9-The straight elevator is not used to luxate the lower third molar if:
a-the roots are mesially curved
b-the roots are straight&long
c-the first molar is missing

3. d-Allof the above
10- Abnormal excessive an lead to:
a- Fracture of the tooth
b-fracture of the jaw
c-breakage of the elevator
d-All of the above
11-Suturing of the wound has the following advantages:
a-decrease wound infection
b-decrease pain
c-Rapid healing
d-All of the above
