已知替鲁膦酸（TIL）具有抗吸收和抗炎特性，但其在牙周炎 - 糖尿病（DM）协会中尚未进行评估。本研究旨在研究局部施用TIL对链脲佐菌素诱导的DM大鼠实验性牙周炎（EP）的影响。

已知替鲁膦酸（TIL）具有抗吸收和抗炎特性，但其在牙周炎 - 糖尿病（DM）协会中尚未进行评估。本研究旨在研究局部施用TIL对链脲佐菌素诱导的DM大鼠实验性牙周炎（EP）的影响。

将32只动物（褐家鼠，Wistar）随机分入4组，DM / C（对照），DM / EP，DM / EP / TIL1和DM / EP / TIL3。在EP组中，结扎下颌第一磨牙。在DM / EP / TIL1组和DM / EP / TIL3组，分别将TIL溶液（分别为1mg / kg和3mg / kg）隔日注射到下颌磨牙的牙龈组织10天，直到安乐死。 使用micro-CT，组织形态计量学，免疫组化（耐酒石酸酸性磷酸酶[TRAP]，核因子-κB配体受体激活剂[RANKL]，骨保护素，切割的半胱氨酸蛋白酶3）和定量逆转录 - 聚合酶链式反应（白细胞介素[IL]-1β，血管内皮生长因子[VEGF]）进行分析。

结果发现，在micro-CT分析中，DM / EP / TIL1和DM / EP / TIL3组抑制了牙槽骨吸收（P <0.05）。DM / EP / TIL3组附着丧失减少（P <0.05）。 TIL组TRAP阳性多核细胞数量减少（P <0.05）。 DM / EP / TIL3组的RANKL免疫标记较低（P <0.05）。 TIL治疗可降低IL-1β的基因表达，DM / EP / TIL3组VEGF表达增加（P <0.05）。

结论：局部施用TIL促进了糖尿病大鼠EP对组织破坏的保护作用，并且3mg / kg TIL的剂量在其抗吸收和抗炎作用方面得到最佳结果。
