In the dental field, as compared with hypodermic needle injection which ensures analgesic effect, there is a tendency to take less notice of the anesthesia by surface application. However, the administration of drugs for local anesthesia by injection is accompanied by pain and often makes the patients anxious and dreaded. In this study, we evaluated the analgesic effect of Hurricaine Liquid and Gel (Beutlich Inc., USA) on pains caused by local infiltration anesthesia, scaling of the subgingival culculus, displacement of gum, and stomatitis. Hurricaine Liquid and Gel are widely used as surface analgesic which is aminobenzoic acid type preperation.
This study included 257 cases treated at our dental office in the health center of Kyosan Factory in the period of July 9 to November 15, 1981. 130 of 257 cases were anesthetized with Hurricaine Liquid. In this group, the age of the patients ranged from 20 to 58. 127 of 257 cases were treated with Hurricaine Gel and the age range of this group was from 19 to 62.
This study confirmed that both types Hurricaine were valid in onset and duration of analgesic effects, and the efficacy rates were more than 97% without any side effect. Judging from the result achiebed in this study, Hurricaine seems to be of wide application in cooperation with its fragrance.
