Objective:
To construct an anthropomorphic phantom for periodontal radiography.
Methods:
The phantom material for the spongiosa was produced by melting polyethylene with calcium hydroxyapatite. Compact bone and teeth were simulated by mixing silicone rubber with calcium hydroxyapatite and calcium carbonate respectively.
Results:
Radiographs of the phantom show nearly all the structures relevant for periodontal radiography. Measurements of X-ray attenuation and optical density correspond to those of the human mandible. Any defect in the periodontal bone can be reproduced.
Conclusion:
The new phantom will be useful for research and education.
