Which nerve block is commonly associated with a long-needle technique and targets the mandibular nerve region?

• A. Inferior Alveolar Nerve Block
• B. Inferior Alveolar Part
• C. Infraorbital Block
• D. Mental Nerve Block

Answer: (A)

The essential idea is that to block the mandibular nerve effectively, you need to reach the deep location where the inferior alveolar nerve enters the mandibular canal. That’s achieved with a long-needle technique in the inferior alveolar nerve block. The needle is inserted deep into the pterygomandibular space, near the mandibular foramen, so the anesthetic surrounds the nerve before it branches. This provides numbness to the lower teeth on that side and, via the mental nerve branches, to the lower lip and chin. Other blocks target different regions and don’t require reaching the deep mandibular canal. An infraorbital block anesthetizes the maxillary area through the infraorbital foramen, not the mandibular nerve. A mental nerve block covers only the terminal branch to the chin and lower lip and is more limited. The term described as an “inferior alveolar part” isn’t a standard technique for reaching the mandibular nerve region.
