牙周炎是一种常见的口腔炎症性疾病,可导致牙槽骨丢失,并可能对全身健康产生不利影响。实验动物模型是研究牙周病发病机制和测试新的治疗方法的重要工具。结扎诱导的牙周炎模型经常用于相对较大的动物,包括非人灵长类动物,以评估宿主反应及其在良好控制条件下对牙齿支持组织(牙龈和骨)的影响。尽管小鼠构成了用于机械免疫学研究的最方便和通用的模型(过多的基因工程菌株和免疫试剂),但小鼠口腔的微小尺寸对结扎放置提出了技术挑战。在这份报告中,我们提出了一个简单的方法结扎第二上颌磨牙,而且,确定了最合适的网站,以有效和可重复的方式评估炎性骨丢失。这些优化有望促进小鼠结扎诱导的牙周炎模型的使用,从而有助于更好地了解牙周炎的免疫病理机制。
Periodontitis is a prevalent oral inflammatory disease that leads to alveolar bone loss and may exert an adverse impact on systemic health. Experimental animal models are critical tools to investigate mechanisms of periodontal pathogenesis and test new therapeutic approaches. The ligature-induced periodontitis model has been used frequently in relatively large animals, including non-human primates, to assess the host response and its effects on the tooth-supporting tissues (gingiva and bone) under well-controlled conditions. Although mice constitute the most convenient and versatile model for mechanistic immunological research (plethora of genetically engineered strains and immunological reagents), the tiny size of the murine oral cavity has presented technical challenges for ligature placement. In this report, we present a straightforward method for ligating the second maxillary molar tooth, and, moreover, identified the most appropriate sites for evaluating inflammatory bone loss in a valid and reproducible manner. These optimizations are expected to facilitate the use of the mouse ligature-induced periodontitis model and consequently contribute to better understanding of the immunopathological mechanisms of periodontitis.
