Oral Surgery · single question

An infection that perforates the bone into the vestibular/oral soft tissue (general scenario, location not further specified) most commonly tracks into which fascial space?

  1. Submandibular space
  2. Sublingual space
  3. Buccal space
Show answer and explanation

Correct answer: C. Buccal space

For most maxillary teeth and many mandibular premolar/molar infections that perforate the buccal cortical plate above (maxilla) or below (mandible, depending on the apex's relationship to muscle attachments) the relevant muscle attachments, the buccal space is the most commonly involved fascial space for a simple vestibular/cheek-area swelling, as opposed to the sublingual or submandibular spaces, which require a more specific apex-to-mylohyoid-muscle relationship (mandibular posterior teeth).
