Comparison of the Efficacy and Safety of Two Homologous Active Principles for Local Dental Anesthesia

The day scheduled for the surgery, vital signs (pulse, blood pressure and oxygen saturation) will be recorded prior the administration of the anesthesia. A volume of 1.8 ml of 4% articaine and epinephrine 1: 100000 solution of either the test product or the reference product will be deposited slowly to proceed to the inferior alveolar nerve block (IANB), according to the table of allocation of treatments in each period. The vital signs will continue to be monitored during the procedure, and once the procedure has been completed. If the volunteer needs more anesthetic, this will be recorded and will be administrated according to the maximum permitted doses (7 mg / kg (up to 500 mg) 5 mg / kg in children 7), and immediately after the administration, the vital signs will be taken again.
