Final answer:
The answer is True. When using the Wand for a periodontal ligament injection, the bevel of the needle should be directed toward the bone to effectively deposit the anesthesia into the narrow periodontal ligament space.
Step-by-step explanation:
When administering a periodontal ligament injection (intraligamentary injection) using the Wand, the bevel of the needle should indeed be directed toward the bone. This method is utilized because the periodontal ligament space is very narrow, and positioning the bevel toward the bone can help ensure that the local anesthesia is deposited into the periodontal ligament space effectively.
The injection technique is aimed at numbing the specific tooth without affecting a larger area, preserving the patient's comfort and reducing unnecessary numbness. This precision in dental procedures is important because structures like the mandibular foramen and the lingula are closely involved in the innervation of the lower teeth, and careful technique is required to ensure effective anesthesia.
The answer to this question is True: the bevel of the needle should be directed toward the bone when using the Wand for a periodontal ligament injection.
