Cross-contamination of the PSP sensor in a preclinical setting.

Purpose: This study tested an infection control protocol for photostimulable phosphor (PSP) sensors while simulating multiple uses.

Methods: Dental hygiene students (n=36) were randomly assigned to a control group (dry wipe) or test group (disinfectant wipe). A sterile, barriered sensor was placed in a peer patient's mouth to simulate an exposure.
