Q1: All of the following statements concerning an autogenous free gingival graft are true EXCEPT one.
Which one is the EXCEPTION?
A. it can be placed to prevent further recession
B. it can be used to effectively widen the attached gingiva
C. it retains its own blood supply and is not dependent on the bed of recipient blood vessels
D. the greatest amount of shrinkage occurs within the first 6 weeks
E. it is also useful for covering nonpathologic dehiscences and fenestrations
Answer: it retains its own blood supply and is not dependent on the bed of recipient blood vessels
Q2: Most root amputations involve the:
A. mandibular first and second premolars
O
B. maxillary first and second molars
C. maxillary canines
D. mandibular molars with buccal and lingual class II or III furcation involvements
Answer: maxillary first and second molars
mm
Q3: The main goal of osseous recontouring (surgery) is:
A. to cure periodontal disease
B. to eliminate the existing microflora
O
C. to eliminate periodontal pockets
D. to change the existing microflora
Answer: eliminate periodontal pockets – to reshape the marginal bone to resemble that of the
alveolar process undamaged by periodontal disease

,Q4: All of the following statements regarding periodontal flaps are true EXCEPT one. Which one is the
EXCEPTION?
A. full-thickness periodontal flaps involve reflecting all of the soft tissue, including the periosteum, to
expose the underlying bone
B. the partial-thickness periodontal flap includes only the epithelium and a layer of the underlying
connective tissue
C. both full-thickness and partial-thickness periodontal flaps can be displaced
D. flaps from the palate are considered easier to be displaced than those from any other region
E. flaps should be uniformly thin and pliable
Answer: flaps from the palate are considered easier to be displaced than those from any other
region
Q5: There are various distal flap approaches used for retromolar reduction. The simplest is the:
A. gingivectomy
mug
distalwedge
B. apically positioned flap
distal wedge
C. distal wedge
D. laterally positioned flap
Answer: distal wedge
Lillmlwetse
Q6: Contraindications to gingivectomy include all of the following EXCEPT one. Which one is the
EXCEPTION?
A. the need for bone surgery or examination of the bone shape and morphology
B. situations in which the bottom of the pocket is apical to the mucogingival junction
C. esthetic considerations, particularly in the anterior maxilla
D. elimination of gingival enlargements
Answer: elimination of gingival enlargements

Q7: The primary objective and advantage of surgical flap procedures in the treatment of periodontal
disease is:
A. reduce or eliminate periodontal pockets
B. to provide access to root surfaces for debridement
C. regrowth of alveolar bone
D. maintenance of biological width
E. establishment of adequate soft tissue contours
Answer: to provide access to root surfaces for debridement – all the other choices are goals but
not a primary objective
Q8: The modified Widman flap (MWF) facilitates instrumentation and attempts to reduce pocket depth.
The apically displaced flap improves accessibility and eliminates the pocket, but it does the latter by
apically positioning the soft tissue wall of the pocket.
A. both statements are true
B. both statements are false
C. the first statement is true, the second is false
D. the first statement is false, the second is true
Answer: the first statement is false, the second is true
Q9: A soft tissue graft that is rotated or otherwise repositioned to correct an adjacent defect is called a:
m
A. free gingival graft
oB. pedicle graft
C. connective tissue graft
D. frenectomy
O
Answer: pedicle graft
Q10: What is guided tissue regeneration?
A. a soft tissue graft used to correct mucogingival junction involvement
B. placement of nonresorbable barriers or resorbable membranes and barriers over a bony defect
C. a free gingival graft used to increase the amount of attached gingiva
D. placement of an autograft to treat a bony defect
Dr. Omar Mokhtar
Answer: placement of nonresorbable barriers or resorbable membranes and barriers over a bony
, defect
Q11: The primary reason for the failure of a free gingival autograft is:
A. infection
B. edema
C. disruption of the vascular supply before engraftment
D. the formation of scar tissue
Answer: disruption of the vascular supply before engraftment
Q12: A variation of the laterally positioned flap is called:
A. a coronally positioned flap
mm
B. a modified Widman flap
0
C. a double papilla flap
D. a free gingival flap
Answer: a double papilla flap
double papilla flap
Q13: Which of the following statements is NOT true regarding the conventional flap design?
A. the entire papilla is incorporated in one of the flaps
B. used in cases where the flap needs to be displaced
C. used in instances of too narrow interdental spaces
D. none of the above
Answer: the entire papilla is incorporated in one of the flaps
Q14: Which of the following has a relatively high degree of predictability and is a "workhorse" of
periodontal therapy?
A. coronally displaced (positioned) flap
B. laterally displaced (positioned) flap
C. double papilla flap
D. apically displaced (positioned) flap
Answer: apically displaced (positioned) flap
