About intracanal medicaments
Among intracanal medicaments, calcium hydroxide has been the standard in endodontic retreatment for its antimicrobial properties and effect on endotoxins. Its high pH makes the canal alkaline, which disrupts bacterial cell membranes and denatures proteins, and the review calls it highly effective against a broad spectrum of microorganisms. It has limits: it does not eradicate bacteria deep in the dentinal tubules, and its low solubility limits how far it penetrates places such as lateral canals. Chlorhexidine is used with it or in its place: in gel form its viscosity helps it stay in the canal, while the calcium hydroxide keeps its role as a barrier material.
An intracanal medicament is placed in the canal to act on what is left in it; disinfection combines mechanical debridement with these medicaments. The canal preparation materials beside them are the gels and solutions used while the canal is being shaped.
During instrumentation a smear layer forms on the canal walls, which may get in the way of disinfection. EDTA removes it by chelating the calcium in the inorganic part of dentine, and is used as a final rinse together with sodium hypochlorite, which deals with the organic part.
How medicaments, chelating agents and canal prep gels differ
- Medicaments — Left in the canal between visits, rather than rinsed through it. A paste is placed with a syringe, a rotary spiral or a purpose-made carrier.
- EDTA & Chelating Agents — Works on the inorganic part of the smear layer, where hypochlorite works on the organic part.
- Canal Prep Gels & Lubricants — Thick enough to stay where it is put, rather than running through the canal. One study reported the solution forms diffusing better than the viscous gels.
- Pulp Vitality Testers — Cold sprays in a can, filed for pulp vitality testing.
What to look at when choosing a medicament or canal prep material
Placement: one study found a purpose-made paste carrier left a denser fill of calcium hydroxide than a syringe with a finger spreader or a syringe with a rotary spiral.
Getting it out again: the difficulty of removing a medicament from the canal before filling has been reported to work against the result of treatment.
Form: the same active material can come as a paste in a syringe, a powder to mix, a solution or a gel.
