J Periodontol:利用小鼠模型对种植体周围炎和牙周炎的早期干预

2018-03-11 MedSci MedSci原创

种植体周围炎是一种对细菌生物膜的炎症反应,导致骨质流失,最终导致植入失败。由于缺乏可预测的治疗手段,彻底了解种植体周围炎的发病机制至关重要。本研究旨在评估和比较急性诱发的种植体周围炎和刺激移除以后的反应。 在拔除左侧上颌磨牙8周后,将植体置于1月龄C57BL/6J雄性小鼠中。一旦骨整合,将结扎线放置在实验组的植体和对侧第二磨牙周围。对照组不结扎处理。一周后,去除一半结扎线,形成结扎组和去除结扎线组

种植体周围炎是一种对细菌生物膜的炎症反应,导致骨质流失,最终导致植入失败。由于缺乏可预测的治疗手段,彻底了解种植体周围炎的发病机制至关重要。本研究旨在评估和比较急性诱发的种植体周围炎和刺激移除以后的反应。

在拔除左侧上颌磨牙8周后,将植体置于1月龄C57BL/6J雄性小鼠中。一旦骨整合,将结扎线放置在实验组的植体和对侧第二磨牙周围。对照组不结扎处理。一周后,去除一半结扎线,形成结扎组和去除结扎线组。在去除结扎线的第5天和第十四天两个时间点处死小鼠。通过显微计算机断层扫描和组织学分析标本。

结果显示,去除结扎丝后5天和14天,牙周炎组骨量明显增加,而种植体周围炎组则没有。组织学上,植体组均比牙齿组显示更高水平的细胞浸润。破骨细胞数量在种植体周围炎和牙周炎结扎保留组中增加,并且随着结扎线的去除而减少。对于所有组,种植体周围炎的胶原总体上比牙周炎更混乱。种植体周围炎实验组基质金属蛋白酶-8和NF-kB的水平较牙周炎组高。

综上所述,该研究结果表明,与牙齿相比,种植体对结扎丝的反应更慢。未来的研究需要进一步探究种植体周围炎疾病的病理生理学特征。
