Aspiration using prefilled dental anesthetic cartridges.
The purpose of this study was to make clear if aspiration was possible by the non-aspirating technique using non-aspirating cartridges. Four prefilled anesthetic cartridges used in Scandinavia generally were selected for study. The pressure required for aspiration varied between 130--320 mm Hg. In the majority of cases, aspiration did not occur in the pressure of 320 mm Hg. Thus, if the patient has normal blood pressure- the aspiration occurs very seldom by using non-aspirating cartridges.
