What is your treatment protocol for a patient presenting with a periapical abscess and mild swelling? What sequence and intracanal irrigants should we use?

After chemomechanical disinfection, drainage through the canal if possible, irrigation with saline early in the procedure and effective drainage with micro suction are very important. Toward the end, irrigate with sodium hypochlorite and, if the canals are becoming dry, carefully apply CaOH2 without extrusion. If drainage continues and the paper point is still very wet, the canals can be left empty, a temporary filling placed and a dressing appointment arranged within two days. If swelling is severe during this period, antibiotics may be added.
