“…As demonstrated by previous studies, the radiographic detection of incipient caries lesions is challenging, which possibly explains our reduced diagnostic values. 4,10,20 ROC curve (Az values) is influenced by sensitivity and specificity values and, in the present study, was around 0.6, which is similar to the results of previous studies. 9,10 The low sensitivity and high specificity suggest that the clinicians may underestimate early proximal lesions visualizing digital bitewing radiographic images 4 irrespective of the file format.…”

“…An intraoral digital radiograph can be acquired with digital imaging receptors of different types: sensor (charge-coupled device, CCD; complementary metal-oxide semiconductors; CMOS) and phosphor storage plate (PSP). [1][2][3][4] The benefits of digital radiography over the conventional method using analogue film comprise the absence of chemical processing, reduction of the radiation dose delivered to the patient, and the possibility of post-processing image enhancement (e.g. brightness, contrast, and filters), digital storage, and online transmission.…”

A guiding principle of radiation safety is ensuring that radiation dosage is as low as possible while yielding the necessary diagnostic information. Intraoral images taken with conventional dental film have a higher re-exposure rate when taken by dental students compared to experienced staff. The aim of this study was to examine the prevalence of and reasons for re-exposure of digital intraoral images taken by third- and fourth-year dental students in a dental school clinic. At one dental school in Canada, the total number of intraoral images taken by third- and fourth-year dental students, re-exposures, and error descriptions were extracted from patient clinical records for an eight-month period (September 2015 to April 2016). The data were categorized to distinguish between digital images taken with solid-state sensors or photostimulable phosphor plates (PSP). The results showed that 9,397 intraoral images were made, and 1,064 required re-exposure. The most common error requiring re-exposure for bitewing images was an error in placement of the receptor too far mesially or distally (29% for sensors and 18% for PSP). The most common error requiring re-exposure for periapical images was inadequate capture of the periapical area (37% for sensors and 6% for PSP). A retake rate of 11% was calculated, and the common technique errors causing image deficiencies were identified. Educational intervention can now be specifically designed to reduce the retake rate and radiation dose for future patients.

Objective: To evaluate the diagnostic capability of 5th‐year students using digital imaging, conventional bitewing (BW) radiographs, and printed film on paper to detect interproximal caries lesions.Methods: A cross‐sectional study was conducted with senior dental students. Three different radiographs: digital, BW, and printed films on paper were used; thus, nine radiographs, each with a 2‐min viewing time, were considered by students along with a questionnaire. A control group of specialists from Prosthodontics and Radiology had finalized the answers prior to conducting the study. The appropriate responses were divided into five categories: R0: Intact surface, R1: Radiolucency in the outer half of enamel, R2: Radiolucency in the inner half of enamel, R3: Radiolucency in the outer half of dentin, and R4: Radiolucency in the inner half of dentin. Students’ responses were analyzed using a one‐way analysis of variance (ANOVA) test and a t‐test.Results: Ethics for the study was obtained from the institutional committee (Reg No: BM19/9/8). When compared with the control group using ANOVA testing, the results showed good detection accuracy with a success rate of ~64 accuracy. There was a significant difference in the outcomes when detecting the presence of the caries lesion between the three diagnostic techniques (p > 0.001). In detecting the size of the carious lesion, the students’ ability was recorded as poor. The highest average for detecting the presence of the carious lesion was correspondent to the printed film on paper method.Conclusions: Senior dental students have shown good accuracy in detecting the presence but not the size of interproximal caries on all radiographs viewed.Clinical Significance: Teachings and availability of diverse radiological diagnostic techniques ensured a reasonable level of understanding and use of the diagnostic caries risk assessment methodologies as required in restorative treatment planning.
