Resumen

El objetivo de este estudio fue evaluar la eficacia anestésica de la articaína al 4% por la técnica de infiltración vestibular (IV) tras el bloqueo del nervio alveolar inferior (BNAI) con mepivacaína al 2%, ambas con epinefrina 1: 100.000, en el tratamiento de urgencia de molares mandibulares con pulpitis irreversible sintomática (PIS). Se trata de un estudio prospectivo, con un diseño experimental del tipo de ensayo clínico randomizado paralelo controlado y ciego. Treinta pacientes diagnosticados con PIS fueron asignados aleatoriamente, con el grupo control (G1) recibiendo el BNAI con 1.8 mL de mepivacaína, mientras que el grupo experimental (G2) también recibió la IV con 1.8 mL de articaína. Para evaluar la eficacia anestésica, se utilizó el análisis labial y la prueba de sensibilidad eléctrica (PSE). Además, una escala visual analógica verificó la presencia de dolor. Se aplicaron ANOVA de dos vías y la prueba de chi-cuadrado a un nivel de significancia del 5%. Hubo una reducción en la percepción del dolor después de ambas técnicas (p <0,001), sin diferencias entre los grupos (p = 0,479). Las tasas de éxito anestésico fueron 26,6% para BNAI (G1) y 40% para BNAI + IV (G2), sin diferencias significativas entre los dos tratamientos (p = 0,699). La IV con articaína al 4% después de BNAI con mepivacaína al 2%, ambos con epinefrina 1: 100.000, no aumentó significativamente el éxito anestésico en pacientes con PIS.
