Local anaesthesia and dry socket. A clinical investigation of single extractions in male patients

1533 single intra-alveolar permanent tooth extractions in males were investigated in a study to determine if the type and technique of local anaesthesia influenced the occurrence of dry socket. The results show that the incidence of dry socket was significantly greater after the use of Xylocaine compared to Citanest and that the use of repeated injections or intraligamental techniques increased the likelihood of this painful post-extraction condition.
