Question

To accomplish complete anesthesia of the right side palate, which injections are needed?

a. GP nerve block
b. GP and NP nerve block
c. GP, NP and PSA nerve block
d. GP, NP, PSA and infiltration

Answer 1

To achieve complete anesthesia of the right side palate, the Greater Palatine (GP) and Nasopalatine (NP) nerve blocks are needed. The GP block numbs the posterior, and the NP block covers the anterior hard palate. The option (B) is correct.

Step-by-step explanation:

To accomplish complete anesthesia of the right side palate, the injections needed are the Greater Palatine (GP) and Nasopalatine (NP) nerve blocks. The GP nerve block will numb the hard palate and palatal gingiva posterior to the canines, while the NP nerve block will anesthetize the anterior portion of the hard palate, typically up to the area just behind the maxillary incisors.

An additional Posterior Superior Alveolar (PSA) nerve block would be necessary if the anesthesia needs to extend to the molar area of the palate. However, for strictly palatal anesthesia, the GP and NP nerve blocks are usually sufficient. Therefore, option (B) is correct.
