Abstract
Objective:To evaluate the effect of microscopic apical surgery on patients with chronic apical periodontitis(CAP).Method:A total of 80 patients with CAP who admitted to Guilin Stomatological Hospital from January 2021 to December 2022 were selected,they were divided into the control group(40 cases)and the observation group(40 cases)according to random number table method.The control group was given traditional apical surgery,and the observation group was given microscopic apical surgery.The surgical effect,pain condition at 7 d after surgery,periapical index(PAI)score before surgery and 3 months and 6 months after surgery,inflammatory factors in gingival crevicular fluid before surgery and 4 weeks after surgery,complications were compared between two groups.Result:The total effective rate of the observation group(95.00%)was higher than that of the control group(77.50%),and the difference was statistically significant(P<0.05).At 7 d after surgery,the incidence of pain in the observation group(12.50%)was lower than that in the control group(40.00%),and the difference was statistically significant(P<0.05).At 3 months and 6 months after surgery,the PAI scores in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).At 4 weeks after surgery,the levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and interleukin-6(IL-6)in the observation group were lower than those in the control group,the differences were statistically significant(P<0.05).The incidence of complication of the observation group(2.50%)was lower than that of control group(15.00%),and the difference was statistically significant(P<0.05).Conclusion:Microscopic apical surgery for CAP patients can improve the therapeutic effect,reduce inflammation reaction and pain sensation,reduce postoperative complications,and improve periapical conditions.关键词
