Abstract:
Objective:To investigate the efficacy of concentrated growth factor (CGF) in the reduction of pain and swelling after bone augmentation during surgery for odontogenic maxillary cyst.Methods:Sixteen patients with odontogenic maxillary cysts who underwent bone augmentation during surgery between June 2018 and December 2019 were included in this study. They were randomly divided into two groups ( n = 8/group). In the observation group, CGF and bone substitutes were mixed and covered with biofilm. In the control group, bone powder was used to fill the bone cavity, and artificial biofilm was applied. Postoperative swelling, pain, and scar hyperplasia were compared between the two groups. Pain was rated according to visual analogue score. Swelling was divided into three grades according to the level of swelling. Scar was compared according to vancouver scar scale. Statistical analysis was performed using SPSS 20.0 software. Results:The percentage of grade 1-3 swelling in the observation group were 62.5% (5/8), 37.5% (3/8) and 0.0% (0/8), respectively, and they were 50.0% (4/8), 37.5% (3/8), 12.5%(1/8), respectively ( Z = -1.71, P > 0.05). There was significant difference in the duration of swelling between observation and control groups [(3.8 ± 0.9) days vs. (5.8 ± 1.4) days, t = 6.88, P < 0.05]. At 3, 7 and 14 days after surgery, visual analogue score was (2.21 ± 0.25) points, (3.75 ± 0.22) points and (0.57 ± 0.13) points in the observation group and it was (3.76 ± 0.18) points, (2.38 ± 0.26) points, and (2.38 ± 0.26) points in the control group ( t = 14.23, t = 11.29, t = 17.61, all P < 0.001). At 1, 2 and 4 weeks after surgery, vancouver scar scale score was (4.26 ± 0.26) points, (1.22 ± 0.13) points and (2.47 ± 0.11) points in the observation group, and it was (6.35 ± 0.27) points, (4.47 ± 0.73) points and (2.77 ± 0.21) points in the control group ( t = 15.77, t = 2.67, t = 3.58, P < 0.001). Conclusion:CGF can promote postoperative bone defect repair and wound healing and reduce postoperative swelling, pain and scar.
