associated facial and
palatal periodontium and gingiva for a limited procedure, it
would be BEST to
administer which of the following local anesthetic
blocks? - ANSWER -

posterior superior alveolar block is also indicated when
instrumenting on the maxillary premolars. - ANSWER -The
statement is correct, but the reason is NOT.
