Study Notes
Dental Nerve Block Techniques and Complications
- Techniques for dental nerve blocks include IAN with Long Buccal, Gow-Gates, Vazirani-Akinosi, and Inferior Alveolar Nerve Block.
- Nerves anesthetized include the inferior alveolar, incisive, mental, and lingual nerves, affecting specific areas of the mandible and oral cavity.
- Indications for these techniques include procedures on multiple mandibular teeth, buccal and lingual soft tissue anesthesia, with contraindications including infection and limitations in mouth opening.
- Landmarks and positioning are crucial for successful Inferior Alveolar Nerve Blocks, with potential complications such as transient facial paralysis and the need for proper bone contact.
- Inadequate anesthesia with the IAN Block can result from low or anterior injection, as well as accessory innervation, with corrective actions detailed for each scenario.
- Disadvantages of the IAN Block include a wide area of anesthesia, high rate of inadequate anesthesia, and discomforting lingual and lower lip anesthesia.
- The Incisive Nerve Block, a terminal branch of the IAN, provides pulpal anesthesia without lingual anesthesia and is indicated for multiple anterior teeth treatments.
- The Buccal Nerve Block, indicated for buccal soft tissue anesthesia in the molar region, has a high success rate but a potential for pain if the needle contacts the periosteum.
- Positive aspiration rates vary for different techniques, with the Buccal Nerve Block having a 0% rate, and the Incisive Nerve Block having a 5.7% rate.
- Complications such as pain during soft tissue incision after a successful IAN block or transient facial paralysis due to parotid gland proximity are important considerations for dental practitioners.
- Overall, the text emphasizes the importance of precise technique, understanding potential complications, and selecting the most appropriate nerve block for specific dental procedures.
