Effects of glove powder on radiographic quality.
The use of powered rubber gloves in the provision of dental care has produced a new variable in radiographic quality assurance procedures. Wearing powder-coated gloves while processing X-ray films can reduce the quality of the images obtained on processed radiographic film. To ensure that the optimum quality of processed film images is achieved, the operator must be careful to prevent the contamination of the film and processing solutions with powder.
Determining the radiation exposure from visual display terminals used in dentistry.
Computers are rapidly becoming incorporated into all aspects of dentistry, including administrative, didactic and research functions. Of particular concern for dentists are women of childbearing age who are regularly employed as receptionists and secretaries in private dental practices and teaching institutions. Thermoluminescent dosimeter pellets of lithium fluoride were attached directly to the surface of 10 VDT's of varying age and from different manufacturers. The purpose was to compare the amounts of radiation emitted from personal computers that are commonly used in dental practices and teaching institutions. All of the machines tested met USNRC regulations for safety by emitting only negligible amounts of radiation.

Reevaluation of the Fexitron 845.
The concept of flash radiography resulted in the development of the Fexitron 845 in the 1960s. Limitations in the technology of screen films (calcium tungstate) at that time displaced the Fexitron as a useful adjunct for clinical dentistry. The recent introduction of the more efficient rare-earth screens requires a reevaluation of the Fexitron 845. This study retests the efficacy of the Fexitron 845 for clinical diagnosis.
