An estimation of somatic hazards to the United States population from dental radiography.

Recently, data have become available pertaining both to the estimated somatic hazard from exposure of populations to low doses of ionizing radiation and to the extent of exposure resulting from dental radiography. This has made possible an estimation of the somatic hazard to the United States population from dental radiography. It is concluded that the greatest risk of lethality would result from induction of leukemia, but that the actual hazard is probably quite low. It is advised that all procedures which will reduce the radiation exposure to the patient consistent with diagnostic requirements should be employed in order to minimize the potential risk.

Oral radiographic changes in patients with progressive systemic sclerosis (scleroderma).

Intraoral and panoramic radiographs were made of 35 patients with progressive systemic sclerosis. Of those patients, 13 (37%) were found to have abnormally thickened periodontal ligament spaces. Six of the 35 demonstrated mild to significant resorption of the posterior mandibular angle. Three patients, including two showing angle resorption also had some degree of coronoid process destruction. All patients with this disease should receive initial and follow-up panoramic radiographic examinations to determine any osseous changes.
