All the questions have been directly picked from Carranza 11th edition
1. Aim of scaling and root planing before periodontal surgery is
a.
eliminate some lesions entirely
b.
render the tissues more firm and consistent,
thus permitting a more accurate and delicate surgery
c.

All of the above
Hint✅🔑
Ans: D
2.
Prophylactic use of antibiotics in patients who

a.
Is required for subgingival scaling
b.
Is required for curettage procedures and root
planing
c.
Is required for bone grafting procedures
d.
Is not required.
Hint✅🔑
Ans: C
·
The prophylactic use of antibiotics in patients
who are otherwise healthy has been advocated for bone-grafting procedures and
purported to enhance the chances of new attachment.
3.
Periogard is
a.
Diagnostic tool to detect microorganisms
b.
chlorhexidine gluconate
c.
used to measure GCF
d.
periopack used to protect the gingiva after
surgery
Hint✅🔑
Ans: B
·
Oral rinse with 0.12% chlorhexidine gluconate is
available as Peridex or PerioGard.
4.
The simplest, least invasive method to alleviate
anxiety in the dental office is
a.
Nitrous oxide and oxygen inhalation sedation
b.
Midazolam sedation
c.
Local anesthesia
d.
Benzodiazepine
Hint✅🔑
Ans: A
·
Inhalation sedation with nitrous oxide and
oxygen is a safe, effective, and reliable means of reducing mild anxiety.
5.
Swelling after surgical procedures
a.
The swelling generally begins 1 to 2 hours after
the operation and subsides gradually in 3 or 4 days.
b.
The swelling generally begins 1 to 2 days after
the operation and subsides gradually in 3 or 4 days.
c.
If occurs, never apply moist heat over the
operated area.
d.
Is a warning sign of surgical failure.
Hint✅🔑
Ans: B
·
Swelling is not unusual, particularly in areas
that required extensive surgical procedures.
·
The swelling generally begins 1 to 2 days after
the operation and subsides gradually in 3 or 4 days.
·
If this occurs, apply moist heat over the
operated area.
6)
Post surgical sensitivity to percussion is
caused by
a.
Deficient pack
b.
Extension of inflammation into the periodontal
ligament
c.
Trauma to the periodontal ligament
d.
All of the above
Hint✅🔑
Ans: B
·
Sensitivity to percussion may also be caused by the excess pack, which interferes with the occlusion.
·
Removal of the excess usually corrects the
condition.
7)
True about Root hypersensitivity is
a.
hypersensitivity may increase the level of
plaque
b.
plaque accumulation increases hypersensitivity
c.
both are true
d.
none
Hint✅🔑
Ans: C
8) Anesthesia of choice in hospital periodontal
surgery is
a.
General Anesthesia
b.
Local Anesthesia
c.
Conscious sedation
d.
Opioids
Hint✅🔑
Ans: B
9)
Interdental incision is given with
a.
Scalpel
b.
Kirkland knife
c.
BP blade
d.
Merrifield knife
Hint✅🔑
Ans: D
The Orban knife #1-2 and the Merrifield knife #1, 2, 3, and
4 are used for interdental areas. These spear-shaped
knives.
10) electrosurgery or radiosurgery uses electrical
(radio) currents in the range of
a.
1.0-1.5 million cycles per second, or megahertz
b.
10.5-17.5 million cycles per second, or
megahertz
c.
8.5-9.5 million cycles per second, or megahertz
d.
1.5 to 7.5 million cycles per second, or
megahertz
Hint✅🔑
Ans: D
11)
Loop electrodes in periodontal electrosurgery are
used for
a.
Incising
b.
Excising
c.
Planing tissue
d.
Coagulation procedures
Hint✅🔑
Ans: C
There are three classes of active electrodes: single-wire
electrodes for incising or excising; loop electrodes for planing tissue; and
heavy, bulkier electrodes for coagulation procedures.
12)
Curettes used in surgery have
a.
Narrower blades than those used for conventional
scaling and root planing.
b.
Less surface area than those used for
conventional scaling and root planing
c.
Wider blades than those used for conventional
scaling and root planing
d.
No blades.
Hint✅🔑
Ans: C
