According to the principle of randomized group,the control group were treated with AH-Plus warm vertical technique and the study group were with i Root SP single-tip filling. The root canal filling time,postoperative pain rate,and six months follow-up of clinical effect were compared. Results:The time of filling the root canal in the control group was( 119. 00 ± 19. 377) s,and in the study group was( 100. 67 ± 12. 65)s. There was statistically significant difference( P 0. 05). Comparing postoperative pain scores at 24 h,48 h,and 72 h after operation,study group was less painful( P 0. 05).
