J Periodontol:比较埃及蜂胶与纳米羟基磷灰石移植治疗犬Ⅱ类根分叉性缺损的效果

2018-11-15 MedSci MedSci原创

在临床实践中,补充和替代医学方法正在取得进展。蜂胶是一种蜂产品,有人认为它具有骨再生作用。本研究旨在比较埃及蜂胶与纳米羟基磷灰石移植物对杂种狗根分叉骨缺损再生的有效性。

临床实践中,补充和替代医学方法正在取得进展。蜂胶是一种蜂产品,有人认为它具有骨再生作用。本研究旨在比较埃及蜂胶与纳米羟基磷灰石移植物对杂种狗根分叉骨缺损再生的有效性。

方法:在六只临床健康的杂种狗中使用了分口对照设计。在下颌第三和第四前磨牙处通过手术创建了24个II级根分叉缺损。右侧缺损用纳米羟基磷灰石填充物填充,用胶原膜覆盖,左侧缺损用蜂胶填充,也用胶原膜覆盖。术后 1个月和3个月后处死狗。获取缺损区段用于组织学评估。

结果:一个月后的组织学评估显示两个治疗组中新形成的骨。然而,3个月后,骨小梁在胶原/纳米羟基磷灰石组中比在胶原/蜂胶组中显得更薄。与胶原/纳米羟基磷灰石组相比,组织形态学评估显示胶原/蜂胶组的骨高度和骨表面积显着增加。

埃及蜂胶和纳米羟基磷灰石材料均表现出良好的牙周再生效果。蜂胶组细胞增殖能力增强,有利于减少牙周治疗后所需的愈合时间。
