What is the needle insertion site for the buccal nerve block?

The buccal nerve block targets the buccal nerve, which provides sensory innervation to the buccal (cheek) mucosa and the gingiva in the area of the mandibular molars. Therefore, the appropriate needle insertion site is at the buccal mucosa around the mandibular last molar. This location allows for effective deposition of the anesthetic agent to achieve anesthesia in the intended region, including the lower molars and surrounding areas.

In practice, this is crucial as it ensures that the anesthetic can adequately numb the appropriate tissues for procedures involving the mandibular molars, where patient comfort is essential. The accessibility of the site also facilitates better injection technique, which is key for a successful nerve block.
