In this study the effectiveness of the periodontal ligament injection was tested in rats. Anesthetic solutions with carbon dye were injected into the crestal periodontal ligament space under back-pressure. Vital microscopic observations showed that the solution spreads via an intraosseous path into the vessels of the pulp. These results support the contention that the periodontal ligament injection is intravascular in nature. Therefore, possible cardiovascular responses to periodontal ligament injections containing catecholamines must be considered.
在本研究中，对大鼠进行了牙周韧带注射有效性的测试。将含有碳染料的麻醉溶液在背压下注入牙槽嵴顶牙周韧带间隙。活体显微镜观察表明，溶液通过骨内途径扩散到牙髓血管中。这些结果支持了牙周韧带注射本质上是血管内注射的观点。因此，必须考虑对含儿茶酚胺的牙周韧带注射可能产生的心血管反应。
