Currently, there is no gold-standard regenerative material for the treatment of furcation defects. The use of bone grafts in combination with guided tissue regeneration membrane is a predictable treatment option but is expensive. Platelet concentrates are increasingly being used owing to their ease of use and cost-effectiveness.
The aim of this study is to evaluate the ability of platelet-rich fibrin (PRF) to augment the regenerative effects exerted by demineralized freeze-dried bone allograft (DFDBA) in the treatment of mandibular degree II furcation defects.
Twenty-eight defects in 14 patients with bilateral Degree II mandibular furcation defects were included in the study. The test group was treated with a combination of DFDBA and PRF, while in the control group DFDBA was used alone. Clinical parameters such as probing depth, relative vertical clinical attachment level, relative horizontal clinical attachment level (RHCAL), gingival margin level (GML), plaque index, and sulcus bleeding index were measured at baseline and 6 months. Radiographic parameters, such as vertical defect depth, horizontal defect depth and defect fill, were measured using cone beam computed tomography, taken at baseline and 6 months.
The intragroup and intergroup comparisons were done using the paired -test.
The intergroup comparison of mean change in the parameters showed, statistically significant difference in RHCAL (<0.001) and GML (0.014), and no significant difference in other parameters.
Within the limitations of the present study, PRF seems to favor soft-tissue healing but has no additional benefit in bone regeneration when used in combination with DFDBA.
目前,治疗根分叉病变尚无金标准的再生材料。骨移植联合引导组织再生膜是一种可预测的治疗选择,但费用昂贵。由于使用方便且具有成本效益,血小板浓缩物的应用越来越广泛。
本研究旨在评估富血小板纤维蛋白(PRF)增强脱矿冻干骨同种异体移植物(DFDBA)治疗下颌Ⅱ度根分叉病变再生效果的能力。
本研究纳入14例双侧下颌Ⅱ度根分叉病变患者的28处病变。试验组采用DFDBA联合PRF治疗,而对照组仅使用DFDBA。在基线和6个月时测量临床参数,如探诊深度、相对垂直临床附着水平、相对水平临床附着水平(RHCAL)、牙龈边缘水平(GML)、菌斑指数和龈沟出血指数。使用锥形束计算机断层扫描测量基线和6个月时的影像学参数,如垂直缺损深度、水平缺损深度和缺损填充情况。
采用配对t检验进行组内和组间比较。
参数平均变化的组间比较显示,RHCAL(<0.001)和GML(0.014)有统计学显著差异,其他参数无显著差异。
在本研究的局限性范围内,PRF似乎有利于软组织愈合,但与DFDBA联合使用时在骨再生方面无额外益处。
