Value of Oral Repair Membrane and Autologous Concentration of Growth Factor After Curettage of Odontogenic Jaw Cyst
Objective To analyze the value of oral repair membrane and autologous concentration of growth factor after curettage of odontogenic jaw cyst.Methods From January 2017 to December 2021,108 patients with odontogenic jaw cyst underwent curettage in Stomatology Department of Zhengzhou Yihe Hospital and were randomly divided into 3 groups with 36 cases each.Group A was treated without any treatment after surgery,group B was treated with autologous concentrated growth factor+bone meal to fill the surface of the bone defect area,group C was treated with autologous concentrated growth factor+bone meal to fill the surface of the bone defect area with oral repair membrane to cover the wound area.The conical beam computerized tomography was performed at 3,6 and 12 months after surgery to measure the HU values in the bone defect area,as well as the coronal,sagittal and cross-sectional HU values of the curved body slice and CBCT,and the number of teeth that lost function and recovered after surgery to evaluate the effect of bone recovery.Results At 6 months after operation,the HU values of curved body slice,coronal plane,sagittal plane and cross section in 3 groups were higher than those at 3 months after operation(P＜0.05).At 12 months after surgery,HU values of curved body slice,coronal plane,sagittal plane and cross section in 3 groups were higher than those at 6 months after surgery(P＜0.05).At 3,6 and 12 months after operation,the HU values of surface body slice,coronal plane,sagittal plane and cross section in group C were higher than those in group B and group A,and pairwise comparison between groups showed statistically significant differences(P＜0.05).Before surgery,there was no significant difference in CT value of bone defect area and array of teeth with loss of function among 3 groups(P＞0.05).At 6 months after surgery,the CT value of bone defect area and the number of teeth restored to normal in 3 groups were higher than that at 3 months after surgery(P＜0.05).At 12 months after surgery,the CT value of bone defect area and the number of teeth restored to normal in 3 groups were higher than that at 6 months after surgery(P＜0.05).At 3,6 and 12 months after surgery,CT value of bone defect area and number of restored normal teeth in group C were higher than those in group B and group A,and the difference was statistically significant(P＜0.05).Conclusion After curettage of odontogenic jaw cyst,the use of autologous concentrated growth factor+bone powder filling can improve the effect of bone recovery,promote tooth recovery,and provide guidance for clinical jaw defect repair.
