Abstract
Deflection of conventional and newly introduced nondeflecting dental local anesthetic needles were compared in vitro by radiographic examination of the course of the needles in a hydrocolloid impression material. Results indicated significantly less deflection of the new needles when compared to a variety of conventional needles. Controlled clinical trials will be required to test the significance of this finding.
摘要
通过在水胶体印模材料中对牙科局部麻醉针的走行进行X线检查，在体外比较了传统牙科局部麻醉针和新推出的无偏斜牙科局部麻醉针的偏斜情况。结果表明，与多种传统针相比，新针的偏斜明显更小。需要进行对照临床试验来检验这一发现的意义。
