Exodontics Flashcards
What preanesthetic blood work should be done besides the basic CBC?
Platelet count
What are the instruments needed for extractions?
Scalpel handle and 11 blade, dental/periosteal/winged elevator, burs, root tip picks, irrigation, periodontal scissors, needle holder, suture scissors
What type of suture and needle are good for extractions?
Absorbable and swaged needle
What’s the difference between a luxator and an elevator?
Luxators have thin, flat blades for cutting the periodontal ligament and expanding the alveolus (tooth socket).
What are periosteal elevators for?
Elevate gingival tissue and periosteum from the bone, not used deeply sub gingivally
What is the best approach to extractions?
Stretch and tear the periodontal ligament fibers, use a rotational motion and ease root from the socket
What are surgical flaps for?
To cover the hole left by the extraction
For multi-rooted teeth, what must be done before extracting?
Split each root. For 2 rooted teeth, use a high speed bur to cut between furcation and crown tip.
What is the purpose of periodontal surgery?
Eliminate pockets and keep them from returning
What is periodontal debridement?
Exposing the tooth and associated bone, and thoroughly clean area, may/not shape the bone, then gingiva is sutured back. Gingival height can also be changed to reduce pocket depth.
What is a gingivectomy for? Contraindications?
Gingival hyperplasia.
Don’t do it when attached gingiva is minimal or absent with horizontal bone loss
What does a gingivoplasty do?
Reduces gingival height to lessen depth of a pocket
What are indications of open flap root planing?
If conservative treatment methods fail, or if pocket is over 5 mm
What is postop care for an oronasal fistula?
Soft food, no handling the mouth for 2 weeks, ecollar and meds
How is an oronasal fistula repaired?
Using flaps
