title: Pain sensation related to local anesthesia injected at varying temperatures.
abstract: The purpose of the study was to determine whether local anesthetic solution warmed to body temperature (37° C) produced less pain on injection than an anesthetic solution injected at room temperature (21° C) and to determine which solution resulted in quicker anesthetic onset. It was found that the subjects experienced no difference in pain during injection of warm and cold anesthetic solution given respectively in the maxillary buccal sulcus area. The time of anesthetic onset was also not influenced by solution temperature.
