Do barrier envelopes keep PSP plates safe?
The advent of digital intraoral radiography has created new infection-control challenges for dental offices that previously were not an issue with film-based imaging. Because photostimulable phosphor (PSP) and solid-state sensors cannot be autoclaved, barrier envelopes are used to prevent cross-contamination between uses. But studies have shown that, despite the use of barriers, bacterial contamination of the sensors used in digital radiography continues to occur (Journal of Dental Hygiene, Summer 2005,
