Clinical observation of iRoot SP single tip method for sinus periapical periodontitis

Objective To evaluate the clinical efficacy of iRoot SP single-tip filling and iRoot SP warm vertical technique in patients with chronic apical periodontitis with sinus in posterior teeth. Methods A total of 100 posterior teeth diagnosed as chronic apical periodontitis with sinus were selected as research object from March 2018 to February 2019. According to the random number table, each group has 50 cases. The control group were treated with iRoot SP warm vertical technique and the study group were with iRoot SP single-tip filling. Pain rate 1 week after operation, sinus status 2 weeks after operation, apical shadow 3, 6 months after operation and 6 months follow-up of clinical effect were compared. Results Compared with the pain score at 1 week after operation, the response rates of the study group and the control group were 24.0% and 20.0%, respectively, with no significant difference(χ²=0.233, P=0.629);the sinus healing rates at 2 weeks after operation were 96.0% and 94.0%, respectively, with no significant difference(χ²=0.001, P>0.999);the effective rates of the study group and the control group at 3 months after operation were 100.0% and 76.0%, respectively, the difference was statistically significant(χ²=13.636, P=0.001). Six months after operation, the effective rates of the study group and the control group were 100.0% and 96.0%, respectively, with no statistically significant difference(χ²=0.501, P=0.475). Six months after operation, the comprehensive efficacy evaluation showed that the effective rates of the study group and the control group were 98.0% and 96.0%, respectively, with no statistically significant difference(χ²<0.001, P>0.999). Conclusion iRoot SP single-tip method for chronic apical periodontitis patients is with high filling efficiency, ease of clinical operation, low incidence of postoperative pain and high treatment success rate, it is worthy of clinical promotion.
