General Principles of Periodontal Surgery

 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.       acquaint the patient with the office and the operator and assistants, thereby reducing the patient's apprehension and fear.

d.      All of the above


  Hintโœ…๐Ÿ”‘ 

Ans: D

 




2.      Prophylactic use of antibiotics in patients who are otherwise healthy

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.



  Hintโœ…๐Ÿ”‘ 

Ans: C

ยท         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



  Hintโœ…๐Ÿ”‘ 

Ans: B

ยท         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



  Hintโœ…๐Ÿ”‘ 

Ans: A

ยท         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.



  Hintโœ…๐Ÿ”‘ 

Ans: B

ยท         Swelling is not unusual, particularly in areas that required extensive surgical procedures.

ยท         The swelling generally begins 1 to 2 days after the operation and subsides gradually in 3 or 4 days.

ยท         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



  Hintโœ…๐Ÿ”‘ 

Ans: B

ยท         Sensitivity to percussion may also be caused by the excess pack, which interferes with the occlusion.

ยท         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



  Hintโœ…๐Ÿ”‘ 

Ans: C

 

8)     Anesthesia of choice in hospital periodontal surgery is

a.       General Anesthesia

b.      Local Anesthesia

c.       Conscious sedation

d.      Opioids



  Hintโœ…๐Ÿ”‘ 

Ans: B

 

9)      Interdental incision is given with

a.       Scalpel

b.      Kirkland knife

c.       BP blade

d.      Merrifield knife



  Hintโœ…๐Ÿ”‘ 

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



  Hintโœ…๐Ÿ”‘ 

Ans: D

 

11)      Loop electrodes in periodontal electrosurgery are used for

a.       Incising

b.      Excising

c.       Planing tissue

d.      Coagulation procedures



  Hintโœ…๐Ÿ”‘ 

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.



  Hintโœ…๐Ÿ”‘ 

Ans: C
