Adult Dental Skull for X-Ray CT
The Adult Dental Skull Phantom is a representational training tool for dental X-ray imaging, developed by True Phantom Solutions, in partnership with Navadha Enterprises. The phantom is suitable for a range of dental imaging exercises, including orthopantomogram (OPG) and periapical radiographic views and is supplied with a sturdy tripod stand for secure, repeatable positioning.

The phantom includes 32 sets of teeth featuring distinct enamel and dentine layers with variable radiographic opacity, and an openable jaw to facilitate intraoral and extraoral X‑ray procedures. Anatomical accuracy is enhanced by purposeful pathology: one molar exhibits a fracture, and one incisor contains a cavity, while all teeth incorporate realistic dentin structure.
