［ABSTRACT］ Objective: To observe the efficacy of two vital pulp conservation medications on postoperative pain in root canal treatment. Methods: Eighty outpatients with chronic pulpitis and chronic perapical periodonititis in anterior teeth were randomized into three treatment groups with different interacanal medications. Group I: calcium hydroxide paste and iodoform group with 30 patients; group II: Zinc oxide eugenol paste group with 30 patients; group III: control group with 20 patients. Pain degree was recorded before surgery; prepared the canals with step back technique and crowndown technique; recorded patients pain degree 496 hours after surgery by Visual analogue scale (VAS); and recorded pain degree when patients returned one week after surgery. Results: Average presurgery pain score was 19.007; average 4 hours postsurgery pain score was 17.861; average 24 hours postsurgery pain score was 15.858; average 48 hours postsurgery pa
