Resumo

O objetivo deste estudo foi avaliar a eficácia anestésica da articaína 4% pela técnica infiltrativa vestibular (IV) após bloqueio do nervo alveolar inferior (BNAI) com mepivacaína 2%, ambos com epinefrina 1:100.000, no tratamento de urgência de molares inferiores com pulpite irreversível sintomática (PIS). Trata-se de um estudo prospectivo, com delineamento experimental do tipo ensaio clínico randomizado paralelo controlado cego. Trinta pacientes com diagnóstico de PIS foram alocados aleatoriamente, sendo que o grupo controle (G1) recebeu o BNAI com 1,8 mL de mepivacaína, enquanto o grupo experimental (G2) recebeu também uma IV suplementar com 1,8 mL de articaína. Para avaliar a eficácia anestésica, além da análise da dormência labial, utilizou-se o teste de sensibilidade elétrico (TSE). Além disso, uma escala analógica visual verificou a presença de dor. Os testes ANOVA de dois fatores e Qui-quadrado foram aplicados a um nível de significância igual a 5%. Houve redução da percepção da dor após as duas técnicas (p <0,001), sem diferença entre os grupos (p = 0,479). A eficácia anestésica foi de 26,6% para o BNAI (G1) e 40% para o BNAI + IV (G2), sem diferença significativa entre os dois tratamentos (p = 0,699). A IV com articaína 4% após o BNAI com mepivacaína 2%, ambos com epinefrina 1:100.000, não aumentou significativamente o sucesso anestésico em pacientes com PIS.
