The aim of this study was to locate the IOF in relation to the infraorbital margin (IOM) and the alveolar bone process of the maxilla at the second premolar for proper injections of local anesthetics, as well as to determine the depth of needle penetration into the pterygopalatine fossa through GPC to avoid serious complications following nerve block anesthesia.

Digital paquimeter was used and had been carried through two bilateral measures: a)sagittal measure; from infraorbital margin until the superior margin of the IOF; b) transversal measure, of the lateral margin of piriformis opening until the medial margin of the IOE using the transversal plan.
