Study Notes

Dr. Alborz Endo Lecture

Steps in endodontic procedure:
- Patient assessment (PA and bwx)
- CBCT if indicated
- Rubber dam isolation
- Caries control/gingivectomy (as needed)
- Determine restorability and build-up
- Canal preparation
- Shaping, cleaning, and obturation
- Post-operative instructions (RX: 600mg ibuprofen q6h prn pain. ABX only if swollen, typically first 72 hours)

Pulpal Diagnosis

Normal pulp
Reversible pulpitis (sharp cold response resolving immediately)
Irreversible pulpitis (two types):
- Symptomatic (sharp cold response with dull/throbbing ache lingering beyond 3-5 seconds)
- Asymptomatic (normal cold response after pulpal exposure)
Necrotic pulp (no response to cold)
Previously treated pulpits (pulpotomy or pulpectomy)

Periradicular Diagnosis

Normal periradicular tissue
Symptomatic periradicular periodontitis (tenderness to percussion)
Asymptomatic periradicular periodontitis (normal to percussion)
Acute periradicular abscess (clinical swelling, with or without drainage)
Chronic periradicular abscess (clinical swelling, with or without drainage)

TTX-Resistant

Tetrodotoxin resistant Na channels (a form of Na channels resistant to local anesthetic)
Up-regulation during inflammation

Hygienic Rubber Dam

Used as a barrier during endo procedures
Latex and non-latex options available
Dental dam clamps (color-coded)
Wedjets (latex and non-latex)
Why bwx?
- Extent of caries
- Height of pulp chamber
