A PA infection from mandibular M2 may directly spread to which areas?

  1. Buccal space & vestibule, sublingual space, submandibular space

  2. Mandibular canal, mental foramen, buccal space

  3. Submental space, sublingual space, pterygoid space

  4. Buccal space, mandibular canal, submental space

The correct answer is: Buccal space & vestibule, sublingual space, submandibular space

A PA infection from mandibular M2 may directly spread to the buccal space and vestibule, sublingual space, and submandibular space. These areas are located closer to the mandibular M2 and are therefore more prone to direct spread of infection. B is incorrect because the mental foramen is not directly connected to the mandibular M2 and the buccal space may have less contact with the tooth area. C is incorrect because the submental space and pterygoid space are further away from the mandibular M2 and may not be directly affected by the infection. D is also incorrect because while the buccal space and mandibular canal may be affected by the infection, the submental space is further away and may not have direct spread of infection from mandibular M2.
