Study Notes
- Root canal treatment requires mechanical instrumentation and irrigation to remove infected tissues and bacteria from the intricately shaped root canal system.
- Use of irrigant solutions during mechanical instrumentation (chemomechanical preparation) aims to reduce microorganisms, dissolve pulp tissue, lubricate, facilitate removal of debris, and open dentinal tubules.
- Ideal root canal irrigants should have a broad antimicrobial spectrum, dissolve tissue, penetrate inaccessible areas, have low surface tension, be stable, relatively cheap, effective germicides and fungicides, non-irritating to periapical tissues, and not negatively impact tooth structure or root canal obturation materials.
- Saline is often preferred due to its mechanical properties and biocompatibility but has limited antimicrobial effect.
- Sodium Hypochloride (NaOCl) is the most commonly used root canal irrigant, effectively dissolving vital and necrotic pulp tissue, and displaying a strong antimicrobial activity. However, it has a low ability to remove the smear layer and should be used carefully to avoid damaging periradicular tissues.
- Chlorhexidine (CHX) is a wide-spectrum antimicrobial agent but has limited tissue dissolving ability and is less effective against gram-negative bacteria, which are predominant in primary endodontic infections.
- Chelation agents, such as EDTA, citric acid, and HEDP, can effectively remove the smear layer but should be used with caution as they may damage dentin if left in the canal for too long or in combination with other irrigants.
Rules to Considered During Irrigation:
- Examine the tooth radiologically and clinically before treatment.
- Understand the anatomy of the region to be treated.
- Use rubber-dam during irrigation.
- Avoid excessive pressure and avoid squeezing the syringe tip into the canal.
- The injector needle should move easily in the canal.
- Introduce irrigation solution slowly into the canal.
- Use special syringe tips for irrigation and distinguish them from anesthesia syringes.
- Implement the necessary treatment plan without panicking during complications.
