Modification designed to improve instruction in intraoral dental radiography
A modification of the Rinn Snap-A-Ray film-holding device which facilitates more accurate visual alignment of cone and film is described. A double-blind study was undertaken to evaluate the modified instrument as compared to the standard instrument. The results indicated a reduction in the number of errors of all types by the modified instrument. The greatest reduction was observed in cone-cutting errors. © 1985.
