Evaluation of Articaine 4% Versus Mepivacaine 2% for Surgery of Molars Thirds: Clinical Trial.

This study will compare the use of Articaine at 4% to that of Mepivacaine at 2% for lower third molar surgeries semi-included and / or included. I will select 16 patients who require surgical treatment for extraction of third molars, aged between 16 and 40 years at the São Paulo State University. These will participate simultaneously in the two groups: Group 1 mepivacaine (MEP) and Group 2 articaine (ART), and the division will be performed by randomization, so that each patient will have each side (right or left) allocated in different groups. The primary evaluation variable will be to compare the pain index in the immediate postoperative period, using Visual Analog Scale (VAS), and will also analyze Hemodynamic Parameters, such as Patient and Operator satisfaction. The results will be submitted to qualitative and quantitative statistical analysis. The descriptive data will be compared using the statistical analysis of variance (ANOVA) and Tukey test with a significance level of 5%.
