RESUMO

The aim of this study was to evaluate the time of onset and duration of pulp anesthetic dose of 1.8 ml of local anesthetic solutions following: 4% hydrochloride articaine associated with epinephrine 1:100.000 (ART 100) and 1:200.000 (ART 200) and 2% hydrochloride of lidocaine associated with epinephrine 1:100.000 (LIDO 100) in alveolar nerve block lower. The sample of the experiment consisted of twenty healthy patients, underwent three appointments for restorative treatment of low complexity in three subsequent lower teeth. The periods of onset and duration of local anesthetic in dental pulp were monitored with an electric stimulator pulp (Vitality Scanner®, Model 2006 - SybronEndo, CA, USA). To analyze and compare the results of onset and duration of the three pulp solutions local anesthetic was used parametric ANOVA test and the test of Bonferroni help with significance level set at 5% (p <0.05). For the period of onset there was no statistically significant difference between any of the three approaches used local anesthetic (p>0.05). Already in relation to the duration of pulp statistically significant difference between ART 100 and LIDO 100 (p = 0000) and between ART 200 and LIDO 100 (p = 0000). Therefore, the onset of the two solutions of articaine were similar to the solution of lidocaine, but both showed duration of anesthetic action superior to the solution of lidocaine.
