The purpose of the present randomized clinical trial study was to compare the effectiveness of Bovine Porous Bone Mineral (BPBM) with and without Plasma Rich in Growth Factors (PRGF) in the treatment of mandibular Class II furcation defects.
In seven patients, nine pairs of symmetric buccal or lingual mandibular class II furcation defects were treated. In each patient, one defect received BPBM (control) and the other received BPBM/PRGF (test) by random assignment. Clinical measurements were made both at baseline and 6-month evaluation.
Similar improvements were observed with both treatment modalities. Significant reductions were gained in the gingival index, probing depth and relative vertical clinical attachment level. Plaque index and gingival recession changes were not significant in both groups. The mean probing depth reductions were 2.67±0.87 mm for the control group and 3.22±1.56 mm for the test group (p<0.001). The mean relative vertical clinical attachment level gains were 1.57±0.96 mm (p<0.001) and 1.65±1.24 mm (p<0.004) in the control and test groups, respectively. In the test group, the relative horizontal clinical attachment level reduced from 5.87±0.96 mm to 4.58±1.02 mm (p<0.02). No significant differences were observed in all clinical parameters 6 months postoperatively between the two groups.
The application of a combined technique using BPBM/PRGF, compared to the BPBM alone, resulted in greater healing, although not significant, in the treatment of mandibular class II furcation defects.
本随机临床试验研究的目的是比较含和不含富生长因子血浆(PRGF)的牛多孔骨矿物质(BPBM)治疗下颌Ⅱ类根分叉病变的有效性。
对7例患者的9对对称的下颌颊侧或舌侧Ⅱ类根分叉病变进行治疗。在每位患者中,一个病变随机接受BPBM(对照组),另一个接受BPBM/PRGF(试验组)。在基线和6个月评估时进行临床测量。
两种治疗方式均观察到相似的改善。牙龈指数、探诊深度和相对垂直临床附着水平均显著降低。两组的菌斑指数和牙龈退缩变化均不显著。对照组的平均探诊深度减少2.67±0.87mm,试验组为3.22±1.56mm(p<0.001)。对照组和试验组的平均相对垂直临床附着水平增加分别为1.57±0.96mm(p<0.001)和1.65±1.24mm(p<0.004)。试验组的相对水平临床附着水平从5.87±0.96mm降至4.58±1.02mm(p<0.02)。两组术后6个月所有临床参数均无显著差异。
与单独使用BPBM相比,应用BPBM/PRGF联合技术治疗下颌Ⅱ类根分叉病变,愈合效果更佳,尽管差异不显著。
