J Dent Res:米诺环素联合手术治疗——6个月随机对照实验结果

2019-05-18 不详 网络

本研究旨在确定局部米诺环素联合手术治疗种植体周围炎的临床、微生物和影像学效果。招募了50名种植体周围炎的患者,进行了局部应用米诺环素或安慰剂软膏的手术治疗。术后1,3和6个月用龈上清创术重复应用米诺环素。在基线和1小时,3小时和6小时评估时测量斑块指数、牙龈指数(GI)、探诊深度(PPD)和探查出血/化脓。在基线和6个月之间分析用锥形束计算机断层扫描测量支持骨水平(SBL)的变化。使用实时聚合酶链

本研究旨在确定局部米诺环素联合手术治疗种植体周围炎的临床、微生物和影像学效果。

招募了50名种植体周围炎的患者,进行了局部应用米诺环素或安慰剂软膏的手术治疗。术后1,3和6个月用龈上清创术重复应用米诺环素。在基线和1小时,3小时和6小时评估时测量斑块指数、牙龈指数(GI)、探诊深度(PPD)和探查出血/化脓。在基线和6个月之间分析用锥形束计算机断层扫描测量支持骨水平(SBL)的变化。使用实时聚合酶链反应进行微生物分析。

结果显示,两组在手术治疗后均表现出临床和放射学测量的改善。试验组和对照组之间的平均PPD变化存在显著差异(分别为2.68±1.73和1.55±1.86 mm,P = 0.039)。各组间平均GI和SBL的变化差异明显(ΔGI:0.83±0.60和0.40±0.68;ΔSBL:分别为0.72±0.56和0.31±0.49 mm,P = 0.026和0.014)。在测试组和对照组中,治疗成功率(定义为PPD <5 mm,探查时没有出血/化脓,并且没有进一步的骨丧失)分别为66.7%和36.3%。直到6个月,两组的红色复合体菌数量趋于减少;然而,没有发现明显的组间差异。试验组中没有患者在6个月时携带牙龈卟啉单胞菌或福赛坦氏菌。

综上所述,该研究结果表明,米诺环素的重复局部使用结合手术治疗在临床参数和影像方面骨恢复提供明显益处,在短愈合期间具有更高的治疗成功率。
