Infection control is of paramount importance after any periodontal therapy to achieve proper wound healing and regeneration of periodontal tissues. Clinicians continuously strive to provide procedures and/or materials that allow for enhanced and rapid wound healing. The regenerative potential of platelet concentrates like platelet-rich fibrin (PRF) has been explored for their anti-inflammatory action and liberation of growth factors; however, research is lacking on the antibacterial properties of platelet-rich gels. The present study was done to assess the antimicrobial activity of PRF and titanium PRF (T-PRF) alone or with antibiotics on periodontal pathogens.
Thirty-three individuals who were willing to donate blood (12 ml) were included in the study. Amoxicillin (AMOX) + metronidazole (METRO) combination or clindamycin (CLINDA) was incorporated into the blood drawn, and this blood was subjected to centrifugation so as to obtain T-PRF and PRF with antibiotics. The antibacterial activity of all the groups was tested on both bacteria that were cultured in their respective media for up to a 4-day period. The data were subjected to independent -test, Tukey test, repeated analysis of variance (ANOVA), and ANOVA.
All individual parameters were compared for antimicrobial activity on both bacteria on all 4 days. A highly statistical difference ( = 0.0001) was observed in all the groups, with the highest inhibition zone produced by PRF-CLINDA, followed by T-PRF-CLINDA. Antimicrobial activity was evident for the observed 4-day period, which declined from day 1 to day 4.
T-PRF/PRF with and without antibiotics exhibited antimicrobial activity on and over the observed 4-day period.
在任何牙周治疗后,感染控制对于实现牙周组织的正常伤口愈合和再生至关重要。临床医生不断努力提供能够促进和加速伤口愈合的程序和/或材料。富含血小板的纤维蛋白(PRF)等血小板浓缩物的再生潜力已因其抗炎作用和生长因子的释放而得到探索;然而,关于富含血小板凝胶的抗菌特性的研究却很缺乏。本研究旨在评估PRF和钛PRF(T-PRF)单独或与抗生素联合对牙周病原体的抗菌活性。
33名愿意献血(12毫升)的个体被纳入研究。将阿莫西林(AMOX)+甲硝唑(METRO)组合或克林霉素(CLINDA)加入抽取的血液中,然后对该血液进行离心,以获得含抗生素的T-PRF和PRF。所有组的抗菌活性均在各自培养基中培养长达4天的两种细菌上进行测试。数据进行独立t检验、Tukey检验、重复方差分析(ANOVA)和方差分析。
在所有4天内,对两种细菌的抗菌活性比较了所有个体参数。在所有组中均观察到高度统计学差异(P = 0.0001),PRF-CLINDA产生的抑菌圈最大,其次是T-PRF-CLINDA。在观察的4天期间,抗菌活性明显,从第1天到第4天有所下降。
含或不含抗生素的T-PRF/PRF在观察的4天期间对牙龈卟啉单胞菌和伴放线聚集杆菌均表现出抗菌活性。
