Irrigation solution for RCT ,when there is infection and draining from the canal is:
a- Sodium hypochlorite
b- Iodine potassium
c- sodium hypochlorite and iodine potassium. ***
Therefore, like citric-acid rinsing, EDTA solution is recommended before the placement of calcium hydroxide. At a 15% concentration, citric acid has been shown to be very effective against anaerobic bacteria.
Solvidont, a bisdequalium acetate, exhibits good antibacterial properties, but also an unfavorable relationship between cytotoxicity and antibacterial efficiency.
Physiologic saline (Nacl) r the most tissue-friendly rinsing solution, but its antibacterial effect is quite low.
Iodine and also potassium iodine are good antiseptics with equally good tissue biocompatibility.
“Betadine” is the commercially available product.
With paraformaldehyde or phenol-containing solutions, on the other hand, the tissue toxicityis higher than the antibacterial efficacy.
