Epinephrine, a vasoconstrictor, is often added to local anesthetics for dental use to enhance and prolong the local anesthetic effect, prevent local anesthetic systematic toxicity, and impart a hemostatic effect. 1 Epinephrine-containing local anesthetics are commonly used for surgical procedures involving the oral cavity and facial bones, such as tooth extraction, radicular cystectomy, implant placement, and jawbone resection. 2 – 5 The vasoconstrictive effect of epinephrine in the maxilla and mandible has not been sufficiently described

In dentistry, local anesthetic is required for invasive surgeries, such as wisdom tooth removal or oral implant placement when general anesthesia is not employed. If the effect of the local anesthetic is inadequate, the patient will often complain of pain, which can be accompanied by elevated heart rate and blood pressure. 1 When surgical invasiveness to the mandible increases, both common infiltration and conduction anesthesia are commonly used concomitantly. The combined use of conduction anesthesia significantly suppresses pain compared

Mask ventilation, along with tracheal intubation, is one of the most basic skills for managing an airway during anesthesia. Facial anomalies are a common cause of difficult mask ventilation, although numerous other factors have been reported. 1 , 2 The long and narrow mandible is a commonly encountered mandibular anomaly. In patients with a long and narrow mandible, the gaps between the corners of the mouth and the lower corners of the mask are likely to prevent an adequate seal, and a gas leak may occur. When we administer general
