Abstract
Objective:To evaluate the postoperation pain levels of one-visit and two-visit root canal therapy of primary teeth.Methods:88 primary teeth with chronic apical periodontitis were randomly divided into two groups(one-visit group and two-visit group).A comparison of the postoperative pain levels at 6,24,48 h and 1 week after therapy was done between the two groups.Results:There was no statistically significant difference between two groups(P0.05) and there was no statistically significant difference at 6,24 and 48 h after treatment(P0.05).There was significant difference at 6 h,24 h and 1 week(P0.05).Conclusion:One-visit root canal therapy for primary teeth has the same clinical efficacy as two-visit in regarding the postoperative pain levels.
