Correct answer: B — It anaesthetises the buccal mucosa and gingiva of the mandibular molars by injecting distal and buccal to the most posterior molar
The long buccal nerve (buccal nerve) block anaesthetises the buccal mucosa, gingiva, and periosteum overlying the mandibular molars. The injection is placed distal and buccal to the most posterior molar in the mandible, depositing solution in the buccal vestibule. It is a supplementary block to the IAN block, which does not anaesthetise the buccal soft tissues of the molars. The buccal nerve is a branch of the anterior division of V3. It is one of the simplest and most reliable dental nerve blocks.
