Abstract:
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 attach-ment loss and CBCT measurements between the two groups(P＞0.05).At 1 year postoperatively,sig-nificant 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 in-trabony 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 radio-logical effects of CPC on the treatment of periodontal intrabony defects.
