Which type of dental radiograph is used to evaluate the relationship between the maxillary and mandibular arches in centric occlusion?

  1. Panoramic radiograph
  2. Lateral cephalometric radiograph
  3. Temporomandibular joint (TMJ) radiograph
  4. Transcranial radiograph
Show answer and explanation

Correct answer: B. Lateral cephalometric radiograph

A LATERAL CEPHALOMETRIC RADIOGRAPH (lateral ceph) is used to evaluate the skeletal and dental relationships between the maxilla and mandible, including in centric occlusion. It shows the sagittal (A-P) skeletal relationship (Class I, II, or III), dental angulation, and soft tissue profile. Panoramic shows all teeth but not inter-arch relationship in occlusion. TMJ and transcranial views are for the TMJ specifically. B is correct.
