“…Dental radiology is a field that could also benefit from prototyping, given the need for phantoms to learn radiographic techniques, avoiding unjustified X‐ray exposure and recurrent examinations 4 . Moreover, the scientific evidence shows that there still is a need for improvement in the training methodologies of intraoral radiographs, considering the high rate of reported errors 5–13 . In this context, this paper presents the use of low‐cost 3D printing as a practical method for training intraoral radiographic techniques.…”

Introduction: 3D printing is experiencing significant growth in the teaching and learning process. This study aims to present a 3D printed skull model for preclinical intraoral radiographic practice.Materials and Methods: Two 3D printed mannequins were created. One mannequin used an STL file of a skull that was edited using two 3D modelling software (Meshmixer and Netfabb). The second mannequin was designed directly from a patient's segmented CBCT data and then converted into an STL file. Both mannequins were printed using fused deposition modelling (FDM) technology and polylactic acid (PLA) filament; teeth for the second mannequin were also printed using digital light processing (DLP). The printed skull bones were attached, the mandible was articulated to the articular fossa of the temporal bone, and the teeth were inserted into the alveoli. Intraoral radiographs of both mannequins were taken using a digital sensor (RVG 5100, Carestream).Results: Both 3D printed mannequins showed satisfactory radiographic appearance, allowing geometric representation of each intraoral radiographic projection, regardless of STL file origin. Anatomical structures, such as the periodontal ligament space, zygomatic process of the maxilla and intermaxillary suture, were represented. The

“…Resultados similares se han reportado, Dos Anjos et al, (12) muestran que las fallas más frecuentes en las técnicas radiográficas ejecutadas por estudiantes de pregrado, se encuentran en la inadecuada angulación vertical con un total de 79 radiografías, representando el 35.44% de la muestra. Por otra parte, Elangovan et al, (5) reportan que los errores más comunes encontrados en su estudio fueron corte de cono 903 (25.5%), angulación vertical 842 (23.8%), posición de la película 817 (23.1%) y angulación horizontal 486 (13.7%). Batool et al, (13) describen como principales errores el corte de cono 234 (64.81%), elongación 27 (7.47%), y superposición de estructuras 16 (4.43%).…”

año. Material y Método: Estudio observacional descriptivo. Se evaluaron 220 radiografías ejecutadas por 55 estudiantes de Odontología de tercer año. La calidad radiográfica fue evaluada por dos investigadores, mediante una pauta creada con cuatro parámetros: posición de la película, angulación horizontal, angulación vertical y rayos X centrado. Fue comparada la calidad según sector radiográfico, anterior y posterior. Se realizó estadística descriptiva y prueba de chi-2 para establecer diferencias entre calidad y sector radiográfico, con un valor de significancia estadística de p<0.05. Resultados: De 220 radiografías, 88 (40%) obtuvieron calidad aceptable y 132 (60%) calidad inaceptable. Los errores corresponden a defectos en la angulación vertical 95 (43.18%), angulación horizontal 76 (34.55%), posición de la película 52 (23.64%) y rayos X centrado 11 (5.00%). Según sector radiográfico, 50 (22.73%) radiografías en anterior y 38 (17.27%) en posterior obtuvieron calidad aceptable, sin diferencias estadísticas según sector radiográfico p>0.05. Conclusión: Las radiografías periapicales tomadas mediante técnica de la bisectriz por estudiantes de Odontología de tercer año, son mayoritariamente de calidad inaceptable, sin diferencias significativas entre sectores.

Objectives This study aimed to evaluate the impact of 3D-printed mannequins on the training of predoctoral students. Methods Two 3D-printed training models were developed: a traditional model that simulates a sound adult patient and a customized model with pathological and physiological changes (impacted third molar and edentulous region). Students accomplished their pre-clinical training divided into a control group (CG, n = 23), which had access to the traditional model, and a test group (TG, n = 20), which had access to both models. Afterward, they performed a full mouth series on patients and filled out a perception questionnaire. Radiographs were evaluated for technical parameters. Descriptive statistics and the Mann-Whitney test were used to compare the groups. Results Students provided positive feedback regarding the use of 3D printing. The TG reported a more realistic training experience than the CG (p = 0.037). Both groups demonstrated good clinical performance (CG = 7.41; TG = 7.52), and no significant differences were observed between them. Conclusions 3D printing is an option for producing simulators for pre-clinical training in Oral Radiology, reducing student stress and increasing confidence during clinical care.
