Oral Anatomy

Tooth morphology, craniofacial anatomy, nerve pathways, muscles of mastication, and blood supply — structured for OSCE, viva, and board exams.

What examiners focus on

  • Tooth morphology — identifying features, root anatomy, and carving landmarks
  • Trigeminal nerve branches — V1, V2, V3 distribution and clinical relevance
  • Dental nerve mapping — superior alveolar, inferior alveolar, lingual, and mental nerve territories
  • Muscles of mastication — origin, insertion, action, and innervation
  • Blood supply to the face and oral cavity — maxillary artery branches
  • TMJ anatomy — disc, ligaments, movements, and dysfunction basics
  • Fascial spaces — boundaries, contents, and routes of infection spread

5 tips for oral anatomy exams

  1. Nerve questions are the most common — know V2 and V3 branches by heart with their clinical relevance to LA and surgery.
  2. Tooth morphology vivas test you on distinguishing features — practice describing what makes each tooth unique in one sentence.
  3. Muscles of mastication always come as a table question — origin, insertion, action, nerve. Have it memorized as a grid.
  4. Fascial space questions link anatomy to oral surgery — know which spaces connect and the danger of spreading to the mediastinum.
  5. TMJ anatomy gets tested alongside dysfunction — know the disc position in open vs closed mouth and what displacement means clinically.
