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.
