RESUMEN
In a random trial on 40 patients undergoing extraction of the third lower molar 0.125 mg of triazolam were administered sublingually to 20 patients and placebo (lactulose solution 66.7%) to 20 patients. The sedative and amnesic effect rapidly appeared after triazolam while the anxiolytic effect was less pronounced. The recovery of psychomotor functions measured by standard psychomotor tests occurred rapidly and all patients were discharged after about 120 min from the end of the surgery. The judgment of the surgeon was positive as far as the anxiolytic and relaxing effects of triazolam was concerned. The patients treated with triazolam moreover appreciated the sedation induced by the drug. No cardiocirculatory complication was observed and the patients showed a considerable stability from the circulatory stand point. The results show that triazolam may represent a safe alternative to the use of other anxiolytic and sedative drugs in the minor surgery of the oral cavity.
