Q

5 categories of endodontic surgery?

A

Abscess drainage
Periapical surgery
Hemisection / root resection
Intentional plantation
Corrective surgery

23
Q

This procedure releases purulent or hemorrhaging transudates and exudates from a focus of liquefaction of necrosis. This relieves pain, increases circulation, and removes potential irritant.

A

Drainage of an abcess

24
Q

Culture and sensitivity test may be required if patient is?

A

Medically compromised or failure to respond to course of antibiotics.

Periapical surgery

41
Q

Surgeon can consider preoperative dose of Penicillin V potassium of ____ grams or Clindamycin _____ mg, 1 hour before the surgery.

A

Penicillin V potassium 1g
Clindamycin 600mg

42
Q

This type of incision is contraindicated for most endodontic surgery as it limits clinician in providing full evaluation of root surface and has greater chance of dehiscence.

A

Semi-lunar incision

43
Q

This type of incision is in the attached gingiva, used successfully in the maxillary anterior region as its major advantage is esthetics. A prerequisite of this incision is a good periodontal health and at least 4mm of attached gingiva.

A

Submarginal incision

44
Q

This type of incision is made into the gingival sulcus, extending into the gingival crest. This is preferred because it provides maximum access and visibility, lower risk of hemorrhage, and allowance for root planing and bone contouring.

A

Full mucoperiosteal incision

45
Q

This suture is used for reapproximating a gingival flap. This is helpful to prevent recession around teeth and existing crowns.

A

Sling suture
