What are the two methods of nasopalatine nerve block injections?

• A. Single injection or series of three injections
• B. Two injections at different sites
• C. Three injections only
• D. Oral topical followed by injection

Answer: (A)

The nasopalatine nerve block targets the nasopalatine nerves as they exit the incisive foramen to anesthetize the anterior hard palate. There are two practical approaches to delivering this block: a single injection placed at the incisive papilla into the incisive canal, or a series of injections (typically three) around that region to ensure the anesthetic reaches the nerves in variations of palatal tissue thickness or anatomy. The single-shot method is the quicker, simpler option, while the three-injection sequence increases reliability when diffusion around the incisive foramen is incomplete. The other listed options don’t reflect how this block is typically performed: it isn’t defined by two injections at different sites, it isn’t limited to three injections only, and it isn’t initiated with oral topical before injection.
