Abstract：Objective To explore the curative effect of one-time root canal filling on chronic pulpitis and periapical periodonti-tis. Methods The clinical data of 89 cases with chronic pulpitis and periapical periodontitis were retrospectively analyzed. These ca-ses were divided into two groups according to different ways of treatment (56 cases in observation group and 33 cases in control group). Patients in observation group were treated by one-time root canal filling;patients in control group were treated by the traditional method of root canal filling for many times. Such index as curative effect, the time when the pain disappeared, time for treatment, medication time after treatment and visiting times were compared. Results The total effective rate in observation group was 92. 86%, and the to-tal effective rate in control group was 93. 94%, with no statistically significant difference ( P>0. 05 ) . There was no statistical differ-ence in time when pain disappeared and treatment duration between the two groups (P>0. 05). However, the visiting time in observa-tion group was significantly less than that of the control group, and the cure time was significantly shorter than the control group, with no statistical significant difference (P<0. 05). Conclusion There was no obvious difference in the curative effect between one-time root canal filling and the traditional method of multiple-time root canal filling for chronic pulpitis and periapical periodontitis; both methods can obviously alleviate the patients' pain. However, the method of one-time root canal filling has short course of treatment, which is therefore worthy to be popularized.
