RESUMO

The aim of this study was to evaluate the efficiency of some anesthetic techniques comparatively, used isolated and associated, in the obtaining of the anesthesia of first mandibular molar with irreversible pulpitis. Sixty patients distributed in six groups (n=10) were anesthetized with articaine with 1:100.000 epinephrine as it proceeds: conventional inferior alveolar nerve block (IANB) (GI, 1,8 mL and GII, 3,6 mL); the Ca-Zoe injection associated to IANB (GIII) and isolated (GV) and the intraosseous injection with the X-Tip System associated to IANB (GIV) and isolated (GVI). For evaluation of the efficiency a visual analogic scale numbered from 0 to 10, corresponding of growing form, was used to the patients symptomatology during the endodontic therapeutics. The level of significance was set at 5%. The Kruskal-Wallis test showed there not to be differences statistically significant among the techniques (p=0,4221) as for the classification of the pain. In relation to the efficiency of the techniques, the qui-square test presented significant differences in the isolated and associated situations (GIII and GIV - p=0,0015; GV and GVI - p <0,0001; GI and GV - p=0,0032, GI and GVI - p <0,0001; GII and GVI - p <0,0001); and no significant in the isolated situations (GI and GII, p=0,1821; GII and GV - p=0,1412). The association of the conventional block with an intraosseous injection was the best option for the anesthesia of the mandibular molar with irreversible pulpitis.
