目前为止,少有研究报道在牙髓感染条件下的直接盖髓。这篇研究的目的是为了评估不同盖髓材料在感染条件下直接盖髓对牙髓的体内和体外反应。

目前为止,少有研究报道在牙髓感染条件下的直接盖髓。这篇研究的目的是为了评估不同盖髓材料在感染条件下直接盖髓对牙髓的体内和体外反应。

研究对人的牙髓细胞施以脂多糖(LPS)刺激,并培养于含Dycal (Dentsply Caulk, Milford, DE), ProRoot MTA (Dentsply Maillefer, Ballaigues, Switzerland)或Endocem MTA (Maruchi, Wonju, South Korea)的培养基。通过实时聚合酶链式反应检测白细胞介素(IL)-1β, IL-6, 牙本质基质蛋白1和牙本质涎磷蛋白的表达。Sprague-Dawley大鼠的上颌磨牙牙髓暴露2天,分别使用Dycal, ProRoot MTA和Endocem MTA对暴露牙髓进行盖髓,并使用树脂改良的玻璃离子进行封闭。随后进行组织学免疫化学的分析。

结果显示,IL-1β和IL-6的表达在施加LPS刺激时上调,添加Dycal, ProRoot MTA和Endocem MTA培养时下调。牙本质基质蛋白1和牙本质涎磷蛋白水平在施以LPS刺激时下降,施加盖髓材料时上升。体内研究显示,1周时,施以Dycal后的炎症要明显高于ProRoot MTA和Endocem MTA,而到了2周时,3者间没有显著性差异。所有3种材料与1周时相比,炎症均明显下降,矿化明显增多。1周时,IL-6的免疫反应呈现强表达。Dycal比ProRoot MTA和Endocem MTA展现出更强的免疫反应。然而,各组在4周时免疫反应明显减小。

结论:成功的直接盖髓取决于更有效的盖髓材料以治疗感染牙髓。
