Hematoma - A Complication of Posterior Superior Alveolar Nerve Block

Posterior Superior Alveolar Nerve Block, a Dilemma for Dental Practitioners - A Case Report

Posterior superior alveolar (PSA) injection technique delivers the local anesthetic agent on to the posterior surface of maxilla targeting posterior superior alveolar branch of maxillary nerve. This nerve block anaesthetizes maxillary molars of the respective side, bone and soft tissues covering these teeth. This technique when administered correctly will provides complete anaesthesia in the de...

A Comparison of 2% Lidocaine and Epinephrine with 3% Mepivacaine in Inferior Alveolar Nerve Block

The purpose of this study was evaluation of anesthesia success rate of 3% mepivacaine compared with 2% lidocaine 1/80000 epinephrine in inferior alveolar nerve block in thirty voluntary students. All of the subjects were healthy and had not received any medicament. They pariticipated for two appointments and each time randomly received an inferior alveolar nerve injection with one of the anesth...

anterior and middle superior alveolar nerve block for anesthesia of maxillary teeth using conventional syringe

background: dental procedures in the maxilla typically require multiple injections and may inadvertently anesthetize facial structures and affect the smile line. to minimize these inconveniences and reduce the number of total injections, a relatively new injection technique has been proposed for maxillary procedures, the anterior and middle superior alveolar (amsa) nerve block, which achieves p...

Cadaveric Study for Intraoral Needle Access to the Infratemporal Fossa: Application to Posterior Superior Alveolar Nerve Block Technique

The posterior superior alveolar (PSA) nerve block is, from an anatomical perspective, challenging because the mandibular ramus and the zygomatic process of the maxilla can interfere with the course of the needle. Dentists empirically know that shifting the patient's mandible to the ipsilateral side can improve visibility and accessibility for such blocks. This cadaveric study aimed to establish...
