Abstract: PURPOSE: To investigate the effect of collagen sponge in the extraction of impacted teeth and the risk of complications. METHODS: A total of 160 patients with impacted teeth extraction were selected from June 2021 to December 2021 in Shanghai Jing'an Dental Clinic. The patients were randomly divided into experimental group and control group, 80 cases in each group. Both groups underwent conventional extraction of impacted teeth, and the control group was rinsed with 20 mL sodium chloride solution after extraction. In the experimental group, on the basis of the control group, columnar collagen sponge was inserted into the extraction wound. Bleeding, postoperative pain score, postoperative swelling degree 7 days after surgery, levels of inflammatory factors[prostaglandin E2(PGE2), myeloperoxidase(MPO), calcitonin gene-related peptide(CGRP)] in gingival crevicular fluid before and after treatment and postoperative complications (restricted opening, inflammatory induration or bruising of maxillofacial region, infection, dry socket) were compared between the two groups. SPSS 22.0 software package was used for data analysis. RESULTS: The postoperative bleeding time of the experimental group was significantly lower than that of the control group(P<0.05). The VAS scores of spontaneous pain and dysphagia in the experimental group were significantly lower than those of the control group(P<0.05). The swelling degree of experimental group was significantly lower than that of control group 7 days after tooth extraction(P<0.05). There was no difference in PGE2, MPO and CGRP between the two groups before treatment(P>0.05). After treatment, PGE2, MPO and CGRP in the two groups were significantly increased(P<0.05), PGE2, MPO and CGRP of the experimental group after treatment were significantly lower than those of the control group after treatment(P<0.05). The incidence of postoperative complications in the experimental group was significantly lower than that in the control group (P<0.05). CONCLUSIONS: Columnar collagen sponge has a good effect in extraction of impacted teeth, and can effectively avoid postoperative complications, and has little influence on inflammatory factors in gingival crevicular fluid, which is worthy of wide application.
