Abstract: INTRODUCTION: The inferior alveolar nerve block has a high percentage of failure in dentistry. To improve this ratio, has been studied different alternatives, as different techniques, as well as anesthetics.OBJECTIVE:Evaluate two different techniques (conventional technique and Vazirani-Akinosi) for inferior alveolar nerve block, and compare them regarding their effectiveness and quantify the percentage of positive aspirations in both techniques.MATERIAL AND METHOD: 160 patients were evaluated for both sex, with 80 undergoing Vazirani-Akinosi technique plus buccal nerve block (G1), and 80 to conventional inferior alveolar nerve block plus buccal nerve block (G2), both groups using a combination of 4% articaine with 1:100.000 epinephrine to buccal nerve block and 2% lidocaine with 1:100.000 epinephrine to inferior alveolar nerve block. We evaluated the amount of positive aspirations, the effectiveness or not of anesthesia (pain) and when it occurred during the surgical procedure.RESULT:There were no statistically significant differences (p = 0.2453) between G1 and G2 observing the positive aspiration. It was obtained efficiency of 90% for both techniques.CONCLUSION: No significant difference between the conventional alveolar inferior nerve block technique and Vazirani-Akinosi alveolar nerve block technique considering the amount of positive aspirations and efficacy, and the use of 4% articaine with 1:100.000 epinephrine in buccal nerve block possibly increased the anesthetic efficacy of both techniques.
O bloqueio do nervo alveolar inferior (BNAI) apresenta alta porcentagem de falha na Odontologia. A fim de melhorar esse índice, vêm-se estudando diferentes alternativas, como diferentes técnicas e soluções anestésicas. Avaliar duas diferentes técnicas - técnica convencional e de Vazirani-Akinosi - para o bloqueio do nervo alveolar inferior, bem como compará-las quanto à sua efetividade e quantificar o percentual de aspirações positivas nas duas diferentes técnicas. Foram avaliados 160 pacientes de ambos os sexos, sendo 80 submetidos ao bloqueio do nervo alveolar inferior de Vazirani-Akinosi e bloqueio do nervo bucal (G1), e 80 submetidos ao bloqueio do nervo alveolar inferior convencional e ao bloqueio do nervo bucal (G2). Em ambos os grupos, utilizou-se a combinação de articaína 4% com epinefrina 1:100.000 para bloqueio do nervo bucal, e lidocaína 2% com epinefrina 1:100.000 para bloqueio do nervo alveolar inferior. Foram avaliados: a quantidade de aspirações positivas, a eficácia da anestesia e o momento em que ocorreu a falha anestésica durante o procedimento cirúrgico. Não houve diferenças estatisticamente significantes (p = 0,2453) entre os grupos G1 e G2 observando-se a eficácia e o índice de aspirações positivas, e o momento em que ocorreu a falha anestésica, observando-se uma maior eficácia de ambas as técnicas, quando comparadas com a literatura (90%). Não houve diferença significativa entre o BNAI pela técnica convencional e o BNAI pela técnica de Vazirani-Akinosi quanto a quantidade de aspirações positivas e eficácia, sendo que o uso da articaína 4% com epinefrina 1:100.000 no bloqueio do nervo bucal possivelmente aumentou a eficácia anestésica de ambas as técnicas
