In a simulation of the clinical technique, a radiopaque solution and a colloidal carbon suspension were injected into the periodontal ligament in dogs by means of a standard syringe. The colloidal carbon method was superior and demonstrated that the injected material was found in soft tissue and adjacent hard structures and in the vessels of the pulps of the immediate and adjacent teeth. The distribution of the dye did not relate to the injection volume and needle location but was consistently more widespread when injections were given under moderate to strong pressure. The technique appears to be a form of intraosseous injection.
在一项临床技术模拟实验中，通过标准注射器将不透射线溶液和胶体碳悬浮液注入犬的牙周膜。胶体碳法更具优势，结果显示注入的物质存在于软组织、相邻硬组织以及紧邻牙齿和相邻牙齿牙髓的血管中。染料的分布与注射量和针头位置无关，但在中等至强压力下注射时，其分布始终更为广泛。该技术似乎是一种骨内注射形式。
