6 In the second study conducted by Kalathingal et al in 2010, Mitis-Salivarius agar was used to confirm oral streptococci as a source of contamination.

6, 7 In the first study conducted by Kalathingal et al in 2009, approximately 57.8% of the PSP plates demonstrated bacterial growth and a microscopic analysis indicated oral flora as the source of the Gram-positive rods sampled from the contaminated plates. Previously, two studies were conducted by the authors to determine whether, despite precautions, PSP plates can become contaminated over time. However, because of the number of personnel involved in the process and the inexperience of the operators, keeping PSP plates disinfected in this type of environment can be challenging. 3, 4, 5 For these reasons, PSP plates may be favored in a teaching environment such as dental school clinics. Additionally, PSP plates have been shown to exhibit a wider range of exposures, less patient discomfort, and a decreased requirement for retakes. 1 In contrast to direct digital sensors, also used for intraoral imaging, the entire surface area of a PSP plate is active. 1, 2 PSP plates are similar to conventional intraoral films in the sense that they are thin and flexible and may be used with the same positioning devices for image acquisition. Digital imaging using photostimulable phosphor (PSP) plates has been available in medical radiology since 1981 and in dental radiology since 1994.
