“…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. Previously, two studies were conducted by the authors to determine whether, despite precautions, PSP plates can become contaminated over time 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 6.…”

PurposeThis study assessed the effectiveness of three antimicrobial mouthrinses in reducing microbial growth on photostimulable phosphor (PSP) plates.Materials and MethodsPrior to performing a full-mouth radiographic survey (FMX), subjects were asked to rinse with one of the three test rinses (Listerine®, Decapinol®, or chlorhexidine oral rinse 0.12%) or to refrain from rinsing. Four PSP plates were sampled from each FMX through collection into sterile containers upon exiting the scanner. Flame-sterilized forceps were used to transfer the PSP plates onto blood agar plates (5% sheep blood agar). The blood agar plates were incubated at 37℃ for up to 72 h. An environmental control blood agar plate was incubated with each batch. Additionally, for control, 25 gas-sterilized PSP plates were plated onto blood agar and analyzed.ResultsThe mean number of bacterial colonies per plate was the lowest in the chlorhexidine group, followed by the Decapinol, Listerine, and the no rinse negative control groups. Only the chlorhexidine and Listerine groups were significantly different (p=0.005). No growth was observed for the 25 gas-sterilized control plates or the environmental control blood agar plates.ConclusionThe mean number of bacterial colonies was the lowest in the chlorhexidine group, followed by the Decapinol, Listerine, and the no rinse groups. Nonetheless, a statistically significant difference was found only in the case of Listerine. Additional research is needed to test whether a higher concentration (0.2%) or longer exposure period (two consecutive 30 s rinse periods) would be helpful in reducing PSP plate contamination further with chlorhexidine.

“…This study along with other previous studies, [1][2][3][5][6][7] however, shows that the contamination of imaging plates during intraoral digital radiography still occurs frequently and is also a difficult issue to solve. Therefore, strictly following infection control guidelines during intraoral digital radiography is highly recommended.…”

“…However, infection control in intraoral digital radiography using both Charge-Coupled Device/Complementary Metal Oxide Semiconductor sensors and imaging plates (or phosphor plates) is still difficult and remains a problem because these two systems must be reused with each new patient but cannot be heat-sterilized. [1][2][3][4] As a result, cross-contamination can occur. Digital intraoral receptors must be covered with protective barriers to prevent contamination.…”

“…[1][2][3]5,6 Methods to prevent cross-contamination include the use of protective barriers accompanied with antiseptic wiping before removing the plate from the protective barrier, 1,3,[7][8][9] or sterilizing the plate using ethylene oxide gas. 6 The feeling of discomfort from using a protective barrier is another issue that should be considered in clinical application and only one study on this issue, by Wenzel et al, 3 has been reported.…”

Objectives: (1) To compare the efficacy of a commercially available hygienic sheath and an alternative plastic bag in preventing contamination of the imaging plate during intraoral radiography and (2) to compare patient discomfort when using the hygienic sheath and the plastic bag. Methods: 60 sterilized Size 2 imaging plates covered with either the hygienic sheath (n 5 30) or the plastic bag (n 5 30) were used to simulate digital periapical radiographic examination in 30 volunteer patients. After disinfection, each plate was swabbed. The swabbed medium was then plated on trypticase soy agar and incubated. Bacterial colonies were counted. Patient discomfort was assessed using a visual analogue scale (VAS) score. The comparison of the number of bacterial colonies and VAS scores between the two groups was tested by paired t-test at p , 0.05. Results: There was no significant difference in the number of bacterial colonies between the two groups (p 5 0.745). Of all the plates, 10% plates yielded bacterial colonies. The mean count of bacterial colonies for both groups was 10-20 CFU ml 21 . However, there was a significant difference between VAS scores for the two systems (p 5 0.000). The mean VAS scores (range 0-10) for patient discomfort for the hygienic sheath group and the plastic bag group were 3.03 and 5.33, respectively. Conclusions: Based on the design of this study, the alternative barrier provided similar results to those commercially available. Regarding the type of barrier envelope, the hygienic sheath induced less discomfort than the plastic bag.
