Assessment of Perception of Pain with E-Speed Film, CCD Sensor and Photostimulable Phosphor Plates for Intraoral Radiographs in Children using Three Pain Rating Scales

AbstractBackground:Dental radiography is an integral part of intraoral evaluation. Children are often uncomfortable during the placement of film or sensor due to the impingement of the soft tissues. Thus, the perception of pain with three intraoral radiographic methods in children was evaluated using three subjective pain rating scales.Aim:To evaluate the discomfort with three different techniques, that is, intraoral periapical (IOPA) radiograph, charge-coupled device (CCD), and photostimulable phosphor (PSP) luminescence (PSPL), using the Wong–Baker Faces Pain Rating Scale (WBFPRS), numerical rating scale, and visual analog scale (VAS).Materials and Methods:A sample of 35 children aged 6–12 years were divided into two groups: group 1 (6–8 years) and group 2 (9–12 years). For each child, simulations of the three radiological methods (IOPA, CCD, and PSPL) were performed. The meaning of each facial expression on the WBFPRS, VAS, and the numbers on the numerical rating scale was explained to each child before the procedure.Statistical Analysis Used:A one-way analysis of variance (ANOVA) test and paired-samples t-test are used.Results:The results revealed that the CCD sensors elicited higher pain scores than those obtained with IOPA and PSPL, whereas the IOPA film showed the least pain score. Higher score values were obtained in group 1 than in group 2, indicating that children aged 6–8 years felt higher discomfort than the 9- to 12-year age group for the same procedure. This difference was statistically significant (P < 0.001).Conclusion:It was concluded that conventional IOPA films were tolerated better by children when compared to PSP plates and CCD sensors.
