inferior alveolar nerve anesthesia

(noun)

Inferior alveolar nerve anesthesia is a technique for dental anesthesia, used to cause numbness to the areas of the face innervated by the inferior alveolar nerve; namely, the lower lip and the teeth and gingivae of the mandible. This procedure attempts to anesthetize the inferior alveolar nerve prior to it entering the mandibular foramen.

  • Dental Anesthesia

    • The most common local anesthetic technique, effective for the lower teeth and jaw, is inferior alveolar nerve anesthesia.
    • Several non-dental nerves are usually anesthetized during an inferior alveolar block.
    • When the inferior alveolar nerve is blocked, the mental nerve is blocked also, resulting in a numb lip and chin.
    • Nerves lying near the point where the inferior alveolar nerve enters the mandible often are also anesthetized during inferior alveolar anesthesia.

    • The muscular diaphragm, which facilitates breathing, is inferior to the lungs, marking the end of the thoracic cavity.
    • Bronchi are innervated by nerves of both the parasympathetic and sympathetic nervous systems that control muscle contraction or relaxation, respectively.
    • Numerous alveoli (sing. alveolus) and alveolar sacs surround the alveolar ducts .
    • The alveolar ducts are attached to the end of each bronchiole; each duct ends in approximately 100 alveolar sacs.
