The periodontal ligament (PDL) injection for mandibular anesthesia in isolated regions was evaluated, using both a conventional syringe and two devices designed for this procedure. A high success rate was achieved, with a low incidence of adverse reaction and highly favorable comment from both patients and administrators. Duration of pulpal anesthesia following the technique described proved adequate for most dental procedures. The newer devices appear to have some advantage over the conventional syringe technique. However, the PDL injection technique can readily be used with any conventional syringe. Further study is recommended to determine the response of periodontal and pulpal tissues.
对用于下颌局部区域麻醉的牙周韧带（PDL）注射进行了评估，使用了传统注射器以及为此程序设计的两种器械。成功率很高，不良反应发生率低，患者和管理人员的评价都非常好。按照所述技术进行的牙髓麻醉持续时间对大多数牙科手术来说是足够的。较新的器械似乎比传统注射器技术有一些优势。然而，PDL注射技术可以很容易地与任何传统注射器一起使用。建议进一步研究以确定牙周组织和牙髓组织的反应。
