Study Notes
Endodontic Instruments and Materials
- Endodontic files and reamers are fabricated from stainless steel, nickel titanium, and alloy wire.
- Gutta percha is used to fill and seal the root canal (obturate).
- Absorbent paper points are used to dry the canal during root canal treatment.
- Irrigant is used to remove debris from the canal during treatment.
- Endodontic files are used to enlarge and smooth the canal.
- Glick is used to remove excess gutta percha and condense it into the canals.
- Endodontic explorer is a long, pointed instrument that aids in locating the canal orifices.
- Rubber stops are placed on reamers and files to mark the length of the root canal.
Anesthetic Syringe
- Aspirating syringe is used for dispensing anesthetic in dentistry.
Topical Anesthetic
- Topical anesthetic is used to desensitize the gag reflex and minimize needle stick pain.
Needle Stick Prevention
- The most common way for a needle stick to occur is when recapping a contaminated syringe.
- To prevent dilution of topical anesthetic, dry the oral mucosa with a 2x2 gauze before application.
