About

AMSA nerve block injection is targeted anterior superior alveolar nerve and middle superior alveolar nerve branches of infraorbital nerve through nutrient canals. Therefore, central to second premolar teeth of one quadrant can be anesthetized. The aim of the present study was to evaluate the efficacy of AMSA nerve block injection at an anterior and a posterior positions compared to commonly administrated site.
