OBJECTIVE: To clarify the role of concentrated growth factors (CGF) in the treatment of periodontal cement defects using calcium phosphate cement (CPC) with self-curing properties.
METHODS: Thirty-six intrabony defects were randomly divided into two groups. The experimental group received CGF+CPC treatment (n=18), while the control group received CPC treatment alone (n=18). The probing depth, clinical attachment loss, and hard tissue filling as measured by cone beam CT (CBCT) were evaluated at baseline and 1 year postoperatively in both groups, and the levels of major growth factors in CGF and serum were compared [platelet-derived growth factor-BB (PDGF-BB), transforming growth factor-β1 (TGF-β1), insulin-like growth factor-1 (IGF-1), and vascular endothelial growth factor (VEGF)].
RESULTS: At baseline, there were no statistically significant differences in probing depth, clinical attachment loss and CBCT measurements between the two groups (P>0.05). At 1 year postoperatively, significant improvements were observed in parameters mentioned above in both groups (P < 0.05). The CGF+CPC group seemed more effective compared with the CPC group in reduction of probing depth [(4.5±1.3) mm vs. (3.2±1.1) mm] and clinical attachment gain [(3.8±0.9) mm vs. (2.0±0.5) mm, P < 0.05]. Compared with the group treated with CPC alone, the hard tissue filling degree shown by CBCT in the CGF+CPC group was significantly increased [the reduction of the depth of the intrabony defects was (3.9±1.2) mm vs. (2.1±0.7) mm, respectively, P < 0.01]. At 1 year post-operatively, the volume of the intrabony defects shown by CBCT in the CGF+CPC group was reduced by (0.031 8±0.004 1) mL, which was significantly more than that in the CPC group [(0.019 7±0.001 2) mL, P < 0.05]. In addition, the concentration of the main growth factors (PDGF-BB, TGF-β1, IGF-1, and VEGF) in CGF were higher than those in serum (P < 0.001).
CONCLUSION: After 1 year of follow-up, the results of the present study indicated that CGF could significantly improve the clinical and radiological effects of CPC on the treatment of periodontal intrabony defects.
