“…Dentistry also needs improved ability to accurately identify lesion depth and lesion cavitation. 34 A variety of dental imaging technologies have been recently introduced, each having developments that may increase caries detection. These new technologies include the Schick 33 (Schick 33) intraoral direct digital sensor (Sirona Dental, Salzburg, Austria), the Planmeca ProMax ® (PanBW) panoramic unit in panoramic bitewing mode (Planmeca Inc.) and the Sirona Orthophos XG3D CBCT (XG3D) in high definition (HD) mode with metal artefact reduction software (MARS) (Sirona Dental).…”

Objectives: Proximal dental caries remains a prevalent disease with only modest detection rates by current diagnostic systems. Many new systems are available without controlled validation of diagnostic efficacy. The objective of this study was to evaluate the diagnostic efficacy of three potentially promising new imaging systems. Methods: This study evaluated the caries detection efficacy of Schick 33 (Sirona Dental, Salzburg, Austria) intraoral digital detector images employing an advanced sharpening filter, Planmeca ProMax ® (Planmeca Inc., Helsinki, Finland) extraoral "panoramic bitewing" images and Sirona Orthophos XG3D (Sirona Dental) CBCT images with advanced artefact reduction. Conventional photostimulable phosphor images served as the control modality. An ex vivo study design using extracted human teeth, ten expert observers and micro-CT ground truth was employed. Results: Receiver operating characteristic analysis indicated similar diagnostic efficacy of all systems (ANOVA p . 0.05). The sensitivity of the Schick 33 images (0.48) was significantly lower than the other modalities (0.53-0.62). The specificity of the Planmeca images (0.86) was significantly lower than Schick 33 (0.96) and XG3D (0.97). The XG3D showed significantly better cavitation detection sensitivity (0.62) than the other modalities (0.48-0.57). Conclusions:The Schick 33 images demonstrated reduced caries sensitivity, whereas the Planmeca panoramic bitewing images demonstrated reduced specificity. XG3D with artefact reduction demonstrated elevated sensitivity and specificity for caries detection, improved depth accuracy and substantially improved cavitation detection. Care must be taken to recognize potential false-positive caries lesions with Planmeca panoramic bitewing images. Use of CBCT for caries detection must be carefully balanced with the presence of metal artefacts, time commitment, financial cost and radiation dose.

“…During the education process of dental students, possibilities to compare clinical and radiographic image of caries lesions could be offered by the aid of computer-aided learning (Mileman et al, 2003(Mileman et al, , 2004Wenzel, 1995). Unfortunately, other alternatives to improve skills of additional didactic instruction, based on lectures and discussion of case reports has not proven to be very effective (Wrbas et al).…”

“…These images could add difficulties to the detection of lesions, due to reported increased physical noise of the radiographic image. (Wenzel et al, 1993;Møystad et al, 1996;Hintze et al, 2002) However, Prapayasatok et al (2006) and Kimmes et al (2006) did not report differences between digitized and conventional radiographs for caries detection, and it was stated that these images could be used for diagnosis.…”

Odontostomat., 11(3):347-352, 2017. ABSTRACT:The purpose of this study was to investigate the accuracy and interobserver reliability of examiners with different levels of clinical experience, when diagnosing radiographic proximal caries lesions. Bitewing radiographs were selected from a patient attending Operative Dentistry Clinic, Universidad de Chile. Radiographic examination was performed by three different groups: A: third year dentistry students, B: fourth year dentistry students, and C: dentist recently graduated. Thirty-two proximal surfaces were scored as: 0, sound; 1: enamel caries; and 2: dentinal caries. The data were analysed and accuracy and interexaminer reliability were calculated. Accuracy values for enamel caries were: A (0.54), B (0.55) and C (0.58), and dentinal caries were: A (0.55), B (0.61) and C (0.63). Interexaminer reliability denoted marginal agreement for all groups, A (0.249), B (0.213) and C (0.282) for enamel caries and A (0.058), B (0.102), and C (0.344) for dentinal caries. The results of this study indicate that the accuracy and interexaminer reliability of bitewing radiographic examination were influenced by the clinical experience when detecting radiographic proximal caries, however low values of accuracy and interexaminer reliability were noted, reinforcing the necessity of improving education and training in radiographic caries detection.
