[Gow-Gates block for beginners].

The study was carried out with two groups of 49 patients to evaluate the incidence of failures and re-injections when the blockade of the mandibular nerve was carried out according to Gow-Gates by untrained young dentists. Such an incidence was compared to that of the blockade of the inferior alveolar nerve by the same dentists trained for this specific task. Both the observed failures and re-injections in the Gow-Gates blockade progressively decrease and disappear, theoretically, after 50 blockades, while they remain almost constant in the inferior alveolar nerve blockade. The induction of the blockade was more prolonged after the Gow-Gates blockade (9 minutes) compared to the inferior alveolar nerve blockade (7 minutes). The pain induced by the injection, that due to the anesthetic and that experienced during the subsequent surgery were lower after the Gow-Gates blockade.
