牙周炎的治疗旨在阻止进行性骨质和附着丧失,并促使牙周组织再生。发表于J Periodontol的一项多中心研究评估了使用釉质基质衍生物(EMD)作为非手术牙周治疗的辅助手段(测试)与单纯非手术治疗(对照)的效果。

该项前瞻性、分口、多中心研究纳入51名在同一牙弓内每个对侧象限至少有2个中度至重度牙周炎(PPD=5-8mm)位点的患者,评估使用和不使用EMD的洁治和根面平整术(SRP)。主要结果变量是12个月后临床附着水平(CAL)的变化。次要变量包括探诊深度(PPD)、探诊出血(BoP)、龈缘水平、牙本质过敏,以及转变为不再需要手术治疗的牙周袋的百分比。

 

结果显示,两种治疗方式的CAL从基线到12个月都有明显变化(P<0.001)(测试组=-2.2±1.5mm,对照组=-2.1±1.3mm),PPD也是如此;组间差异不大。健康位点的PPD(牙周袋<5mm)和转换后的牙周袋(不再需要手术治疗的部位)的百分比方面,观察到明显的差异:测试组79.8% VS. 对照组65.9%。测试部位的牙周病变明显减少(P < 0.05)(测试部位的牙周病为17.8%,对照部位为23.1%)。

综上,该研究结果表明,测试组和对照组治疗都使CAL和PPD得到了明显的改善。EMD和SRP的辅助使用使整个牙周健康得到了明显的改善,减少了BoP的频率,健康PPD的数量增加。
