Alternate irrigation with 1 mL antibiotic-containing solution followed by 4 mL 2.5% sodium hypochlorite solution between each size instrument and the consequent one. The antibiotic-containing solution will be prepared by mixing equal quantities of 1.2 gm Co-amoxiclav solution and 600 mg Clindamycin solution at a ratio of 1:1 by volume.

Irrigation with 5 mL MTAD irrigating solution for 5 minutes between each size instrument and the consequent one.
