The present study aims to evaluate and compare the clinical and radiographic changes obtained through Bioactive Glass (BG) with and without autologous platelet-rich fibrin (PRF) in the treatment of intrabony defects in chronic periodontitis patients.
The present study was a split-mouth randomized controlled clinical trial comprising 20 chronic periodontitis patients (mean age: 35.9 years) having at least one pair of bilateral intrabony defect. Group 1 included 20 sites treated with a combination of BG and autologous PRF whereas 20 sites in Group 2 were treated with BG alone. Probing pocket depth (PPD), clinical attachment level (CAL) and gingival recession (GR) were evaluated at 3 and 6 months and bone fill at 6 months by using cone beam computed tomography (CBCT) analysis. Primary study outcomes were changes in PPD, CAL, GR, and bone fill.
CAL gain was greater in Group 1 (5.05 ± 1.09 mm) when compared with Group 2 (4.2 ± 1.70 mm). Furthermore, a significantly greater bone fill was found in Group 1. At 6 months, statistically significant reduction in PPD in Group 1 and Group 2 was evident.
BG morsel when used in combination with PRF is found to be more effective in gain in CAL, reduction in PPD and achieving greater bone fill as compared with treatment with BG alone in periodontal intrabony defects and is indicative of enhanced periodontal regeneration.
本研究旨在评估和比较生物活性玻璃(BG)联合和不联合自体富血小板纤维蛋白(PRF)治疗慢性牙周炎患者骨内缺损的临床和影像学变化。
本研究为一项分侧随机对照临床试验,纳入 20 例慢性牙周炎患者(平均年龄:35.9 岁),至少有一对双侧骨内缺损。第 1 组 20 个部位采用 BG 联合自体 PRF 治疗,第 2 组 20 个部位采用 BG 单独治疗。采用锥形束 CT(CBCT)分析,于 3 个月和 6 个月评估探诊袋深度(PPD)、临床附着水平(CAL)和牙龈退缩(GR),于 6 个月评估骨填充。主要研究结局为 PPD、CAL、GR 和骨填充的变化。
与第 2 组(4.2±1.70mm)相比,第 1 组(5.05±1.09mm)的 CAL 获得更大。此外,第 1 组的骨填充明显更大。在 6 个月时,第 1 组和第 2 组的 PPD 均有显著减少。
与单独使用 BG 相比,BG 颗粒联合 PRF 用于牙周骨内缺损时,在 CAL 获得、PPD 减少和获得更大的骨填充方面更有效,提示牙周再生增强。
