All the questions have been directly picked from Carranza 11th edition
1. The first incision in a periodontal flap surgery is
a.
Interdental incision
b.
Crevicular incision
c.
Reverse bevel incision
d.
Releasing incision
Hint✅🔑
Ans: C
·
Internal bevel incision has also been termed the
first incision because it is the initial incision in the reflection of a
periodontal flap after crevicular (second) and interdental (third) incisions,
·
Internal bevel incision has also been termed as
reverse bevel incision because its bevel is in the reverse direction from that
of the gingivectomy incision.
·
The first three are also called a horizontal
incisions.
2.
Not an objective of The internal bevel
incision
a.
It
removes the pocket lining
b.
It
conserves the relatively uninvolved outer surface of the gingiva, which,
if apically positioned, becomes attached gingiva
c.
It produces a sharp, thin flap margin for
adaptation to the bone-tooth junction.
d.
It preserves papilla for esthetic purposes.
Hint✅🔑
Ans: D
·
The internal bevel incision starts from a
designated area on the gingiva and is directed to an area at or near the crest
of the bone
3.
An interdental incision is given with
a.
Kirkland knife
b.
#15 BP blade
c.
Orbans knife
d.
Periosteal elevator
Hint✅🔑
Ans: C
·
Kirkland knife is used to give incision on the
facial and lingual aspects of the teeth as well as the distal portion of the distal-most
tooth.
·
Orbans knife is used for the interdental
incision
·
The periosteal elevator is used for blunt
dissection i.e. reflection of the full thickness mucoperiosteal flap.
4.
In case of an envelope flap
a.
An interdental incision is not made
b.
A crevicular incision is not given
c.
The interdental incision is given with orbans
knife.
d.
Vertical releasing incisions are given.
Hint✅🔑
Ans: C
If vertical incisions are not made, the flap is called an
envelope flap.
5.
Not true about Vertical releasing
incision
a.
Blood supply is compromised
b.
Should not extend beyond the mucogingival line
c.
If a single releasing incision is given, the
flap is called a triangular flap and if two releasing incisions are given, the
flap is called a rectangular flap.
d.
Vertical incisions in the lingual and palatal
areas are avoided.
Hint✅🔑
Ans: B
Vertical incisions must extend beyond the mucogingival line,
reaching the alveolar mucosa, to allow for the release of the flap to be
displaced.
6.
3 mm of alveolar bone is to be
recontoured where the alveolar crest is located 3 mm below the crest of the
gingiva. Which type of flap is recommended?
a.
Partial thickness flap
b.
Full thickness flap
c.
Combination of both
d.
Gingivectomy
Hint✅🔑
Ans: C
A combination of full-thickness and partial-thickness flaps
may be indicated to obtain the advantages of both. The flap is started as a
full-thickness procedure, then a partial-thickness flap is made at the apical
portion. In this way, the coronal portion of the bone, which may be subject to
osseous remodeling, is exposed while the remaining bone is protected by the
periosteum.
7.
Which of the following clinical findings has
the greatest effect on the type of incision to be given in periodontal flap
surgery?
a.
Frenal attachment
b.
Depth of the vestibule
c.
Amount of attached gingiva
d.
Probing depth
Hint✅🔑
Ans: C

Correct answer: a . Papilla Preservation
flap
10. The workhorse
of periodontal therapy is
a. Double papilla flap
b. Apically repositioned flap
c. Coronally
displaced flap
d. Laterally

Hint✅🔑
Ans: b Apically repositioned flap
An apically displaced flap has a high

therapy.
11. Apically positioned
flap is placed
a. 1mm coronal to crest of alveolar bone
b. 2mm apical to the crest of alveolar bone
c. At crest of alveolar bone
d. 5mm coronal to the crest of alveolar

frequently performed type of periodontal surgery is
a. Modified Widman Flap
b. undisplaced flap
c. Apically displaced flap
d. papilla Preservation flap
Hint✅🔑

13. Periodontal
flap surgery is most difficult in
a. Incisors (Facially)
b. Incisors(Lingually)
c. Second molars (Facially)
d. Second molars (distally)
Hint✅🔑
Ans: d. Second molars
(distally)
14. Flap
surgeries are mainly done to
a. Correct mucogingival inadequacies
b. Remove diseased granulation tissue
c. Provide access to instrumentation
d. Add bone support where it has been lost
Hint✅🔑
Ans: C. Provide access to instrumentation
·
Flap technique provides adequate visibility and accessibility to root
deposits.
15. Which
incision is not followed in flap surgeries?
a. Crevicular
b. Interdental
c. Internal bevel
d. External bevel
Hint✅🔑
Ans: d External bevel
·
External bevel is given during gingivectomy.

surgery can be best performed
a. One month after completion of the hygienic
phase
b. 4weeks after completion of occlusal
adjustments
c. 8 weeks after completion of the restorative
phase
d. Immediately after completion of the hygienic
phase
Hint✅🔑
Ans: a. One month after completion of the hygienic
phase
18. Which of the
following flap does not reduce the pocket depth?
a. Modified Widman flap
b. Undisplaced flap
c. Apically displaced flap
d. Palatal flap
Hint✅🔑
Ans: A
·
The modified Widman flap facilitates instrumentation for root therapy.
·
It does not attempt to reduce the pocket depth, but it does eliminate the
pocket lining.
·
It is not intended to eliminate or reduce pocket depth, except for the
reduction that occurs in healing by tissue shrinkage.
19. Which of the
following flap increases the width of the attached gingiva?
a. Modified Widman flap
b. Undisplaced flap
c. Apically displaced flap
d. Palatal flap
Hint✅🔑
Ans: C
·
It preserves or increases the width of the attached gingiva by
transforming the previously unattached keratinized pocket wall into attached
tissue.
·
This increase in the width of the attached gingiva is based on the apical
shift of the mucogingival junction, which may include the apical displacement
of the muscle attachments.
20. Internal bevel incisions for modified Widman
flap is
a.
initiated at or near a point just coronal to
where the bottom of the pocket is projected on the outer surface of the gingiva
and directed apical to the crest of the bone.
b.
made as close to the tooth as possible, 0.5 to
1.0 mm and directed to crest of alveolar bone
c.
made 1 to 2 mm from the teeth and directed
apical from the crest of the bone
d.
made 1 to 2 mm from the teeth and directed to
the crest of the bone
Hint✅🔑
ans: D
·
option A is for undisplaced flap
·
option B is for apically displaced flap
·
option C is a distractor for option D
21. Modified
Widman flap was given by
a.
Robiscek et al
b.
Ramfjord and Nissle
c.
Newmann
d.
Widman
Hint✅🔑
Ans: B
·
1974 by Ramfjord and Nissle gave the “modified
Widman flap
22. Modified
Widman Flap differs from the original one as
a.
No vertical releasing incision is given in the
original one
b.
Osseous re-contouring is done in a modified
Widman flap
c.
Blood supply is compromised in the original flap
design
d.
Tooth Sensitivity is higher in the case of the
modified Widman flap.
Ans: C
Hint✅🔑
Difference between
Widman and modified Widman flap:
23. The
incision in the undisplaced flap
a.
Is similar to the modified Widman flap in that
the soft tissue pocket wall is not removed with the initial incision in the undisplaced
flap
b.
Is similar to the modified Widman flap in that
the soft tissue pocket wall is removed with the initial incision in the undisplaced
flap
c.
differs from the modified Widman flap in that
the soft tissue pocket wall is removed with the initial incision in the undisplaced
flap
d.
differs from the modified Widman flap in that
the soft tissue pocket wall is not removed with the initial incision in the undisplaced
flap.
Hint✅🔑
Ans: C
·
Hence may be considered an “internal bevel gingivectomy.”
·
The incision is usually carried to a point
apical to the alveolar crest, depending on the thickness of the tissue.
·
The
thicker the tissue is the more apical the ending point of the incision
24. Not
