Clinical images (A–E) Intraoral views of the proband. The teeth of the proband were typically amber and translucent and showed significant attrition, especially the molar teeth. (F–J) Panoramic radiographs and radiovisiography images. The pulp chambers and root canals of the affected teeth were smaller than those in normal teeth or completely obliterated. Radiographs of the bones and knees revealed no significant osteopenia, bony destruction, periosteal reactions, or evidence of any acute fractures, dislocations or injuries.
