超声骨刀微创拔牙法在下颌水平阻生智齿拔除治疗中的应用分析OA

Objective To explore the application of ultrasonic bone knife minimally invasive tooth extraction method in the treatment of mandibular level impacted wisdom tooth extraction and its impact on patient stress response and aesthetic satisfaction.Methods The research subjects were selected from 108 patients with mandibular horizontal obstructed wisdom teeth who received treatment at Huainan Chaoyang Hospital from April 2019 to July 2023.They were divided into the group A and the group B,with 54 cases in each group.The grouping method used was a random number table method.Traditional tooth extraction method was used to treat patients in the group A,while minimally invasive tooth extraction method using ultrasonic osteotome was used to treat patients in the group B.The follow-up time for both groups after surgery was 6 months.The surgical related indicators,including inflammatory mediators and stress mediators before and 3 d after surgery,quality of life before and at 3 and 6 months after surgery,incidence of intraoperative psychological fear,and complications during follow-up,as well as immediate postoperative aesthetic satisfaction of two groups were compared.Results Compared with the group A,the time surgical of the group B was shorter,intraoperative bleeding,limited mouth opening,and facial swelling were lower(P＜0.05).Compared with before surgery,at 3 d after surgery,the levels of inflammatory mediators in the gingival crevicular fluid of both groups increased,but compared with the group A,the group B were lower(P＜0.05).Compared with before surgery,at 3 d after surgery,the levels of peroxisome proliferator activated receptor(PPARr),reactive oxygen species(ROS),substance P(SP),and serotonin(5-HT)in the gingival crevicular fluid of both groups increased,but the group B were lower than the group A;The levels of glutathione peroxidase(GPx)in gingival crevicular fluid in both groups decreased,but compared with the group A,the group B was higher(P＜0.05).The scores of Short Form of Quality of Life Assessment(SF-36)of the two groups gradually increased over time,and at 3 and 6 months after surgery,compared with the group A,the group B were higher(P＜0.05).The incidence of postoperative fear and the incidence of complications during follow-up in the group B were 16.67％and 5.56％,respectively,lower than 66.67％and 35.19％of the group A(P＜0.05).Immediately after surgery,the aesthetic satisfaction rate of the group B was 96.30％,which was higher than the 83.33％of the group A(P＜0.05).Conclusion Minimally invasive extraction of mandibular impacted wisdom teeth using ultrasonic osteotome could reduce intraoperative bleeding,shorten surgical time,and reduce the occurrence of psychological fear during surgery.It could effectively reduce inflammation and stress reactions in patients,improve their limited mouth opening and facial swelling,and thus improve their quality of life and aesthetic satisfaction,with high safety.
