“…All the patients with the suspect of soft tissue calcification detected in the present sample were referred to specialized physicians to evaluate the need of request ultrasonography, magnetic resonance, or computed tomography that allows a correct diagnosis of the soft tissue calcifications. The suspicion of soft tissue calcification in the original or enhanced images may lead to false‐positive or false‐negative diagnoses (Schroder et al, ). The authors reaffirm the need for these specific examinations cited above to better evaluate and confirm the diagnostic hypothesis, which should not be done using panoramic radiography alone.…”

Objective To assess the influence of subjective enhancement of brightness and contrast of digital panoramic radiographs on the detection of soft tissue calcifications. Materials and Methods In this observational study, 500 digital panoramic radiographs were evaluated by two examiners in consensus, who scored the images for the presence of calcifications for each right and left side of the image. After 30 days, all images were revaluated under subjective manipulation of digital brightness and contrast. Calcifications were classified based on the diagnostic hypothesis: sialolith, tonsillolith, calcified atheroma, phlebolith, rhinolith, maxillary sinus antrolith, synovial chondromatosis, lymph node calcification, stylohyoid ligament, triticeous cartilage, or/and upper horn of thyroid cartilage calcification. For intra‐examiner agreement, 20% of the sample was reevaluated. The Kappa test and McNemar test were used (α = 0.05). Results In original images, calcifications were observed in 44.2% of the patients, and in enhanced images, this number was 70.8%. Many calcifications were detected only in enhanced images, mainly in the diagnostic hypotheses of calcified atheroma and stylohyoid ligament. Intra‐examiner agreement was excellent for the detection of soft tissue calcifications (0.82) and for the classification (0.81). Conclusion Subjective enhancement of brightness and contrast alters the detection of soft tissue calcifications in digital panoramic radiograph.

“…A high interindividual variability of the visual appearance of both normal and abnormal anatomy as well as the phenomena caused by artifacts and superimpositions makes it difficult to detect anomalies [28][29][30][31]. In addition, even panoramic radiographs of apparently "dentally healthy patients" can often show one or more dental or non-dental anomalies [32][33][34][35][36]. Therefore, diagnosing OPTs relies on hybrid search for multiple different targets requiring observers to know all characteristics of potential targets, and match those to actual visual characteristics of radiographs [37].…”

How massed practice improves visual expertise in reading panoramic radiographs in dental students: An eye tracking study

et al. 2020

The interpretation of medical images is an error-prone process that may yield severe consequences for patients. In dental medicine panoramic radiography (OPT) is a frequently used diagnostic procedure. OPTs typically contain multiple, diverse anomalies within one image making the diagnostic process very demanding, rendering students’ development of visual expertise a complex task. Radiograph interpretation is typically taught through massed practice; however, it is not known how effective this approach is nor how it changes students’ visual inspection of radiographs. Therefore, this study investigated how massed practice–an instructional method that entails massed learning of one type of material–affects processing of OPTs and the development of diagnostic performance. From 2017 to 2018, 47 dental students in their first clinical semester diagnosed 10 OPTs before and after their regular massed practice training, which is embedded in their curriculum. The OPTs contained between 3 to 26 to-be-identified anomalies. During massed practice they diagnosed 100 dental radiographs without receiving corrective feedback. The authors recorded students’ eye movements and assessed the number of correctly identified and falsely marked low- and high prevalence anomalies before and after massed practice. Massed practice had a positive effect on detecting anomalies especially with low prevalence (p < .001). After massed practice students covered a larger proportion of the OPTs (p < .001), which was positively related to the detection of low-prevalence anomalies (p = .04). Students also focused longer, more frequently, and earlier on low-prevalence anomalies after massed practice (ps < .001). While massed practice improved visual expertise in dental students with limited prior knowledge, there is still substantial room for improvement. The results suggest integrating massed practice with more deliberate practice, where, for example, corrective feedback is provided, and support is adapted to students’ needs.

“…La relevancia en la identificación de estos hallazgos en la arteria carótida radica en que podría tratarse de placas de ateroma calcificadas las cuales pueden ser un factor predictivo para el desarrollo de accidentes cerebrovasculares (Mupparapu & Kim, 2007). En un meta-análisis reciente, se concluyó que la radiografía panorámica posee una excelente sensibilidad y una buena especificidad con una precisión diagnóstica que fue buena o excelente en el 50 % de los casos (Schroder et al, 2019). Con este estudio es posible también concluir que la radiografía panorámica podría utilizarse como una herramienta de cribaje secundaria para este tipo de pacientes permitiendo realizar actividades de prevención en la población.…”

Radiografía Panorámica: Una Herramienta Invaluable para el Estudio del Componente Óseo y Dental del Territorio Maxilofacial

2021

RESUMEN: La radiografía panorámica es probablemente el examen de rutina más solicitado por los dentistas en el mundo. Entre sus ventajas están su bajo costo, rapidez y mayor seguridad debido a que los formatos digitales han permitido disminuir las dosis y tiempos de exposición a la radiación. Su potencial como herramienta diagnóstica radica en la posibilidad que tiene el clínico de observar el territorio maxilofacial casi en su totalidad, pudiendo realizar un estudio anatómico y morfológico acabado de diferentes regiones. En esta revisión se quiere ofrecer una mirada general de la amplia gama de usos que se le pueden dar a la radiografía panorámica, tanto en la clínica como en el ámbito de la investigación, destacando su potencial como herramienta de diagnóstico y su importancia para algunas áreas de especialidad en odontología.
