Question: 1 / 400

What injections are necessary for the extraction of maxillary canines?

Inferior alveolar & Buccal

Infraorbital & Palatal

The extraction of maxillary canines requires two injections an infraorbital injection and a palatal injection. The first injection is necessary to numb the nerves in the upper jaw, while the palatal injection is necessary to numb the palatal tissues. Option A (Inferior alveolar & Buccal) is incorrect because the inferior alveolar injection only numbs the lower jaw and the buccal injection only numbs the cheek muscles. Option C (Inferior alveolar & Lingual) is also incorrect because the lingual injection only numbs the tongue. Option D (Supraperiosteal & Buccal) is incorrect because the supraperiosteal injection only numbs the gum tissue, which is not necessary for the extraction of maxillary canines. Therefore, option B is the correct answer.
