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.
