“…Saati et al . [ 16 ] compared the diagnostic accuracy of NewTom 3G, Soredex, and Planmeca for detection of anatomical landmarks of dry human mandibles. In contrast to our results, they showed that Crane × 3D had the highest diagnostic accuracy followed by Planmeca and NewTom 3G.…”

“…Wax was used in our study to simulate peri-implant soft tissue as in some previous studies. [ 4 16 ] However, data regarding the effect of soft-tissue simulation on CBCT image quality are limited and further studies are required to better simulate the clinical setting. Also, since artificially created lesions have a distinct border, it is recommended to use acid for the creation of defects with irregular borders to better simulate the clinical setting.…”

Introduction: Cone beam computed tomography (CBCT) has been used for preoperative treatment planning for dental implants, one of the major advantages is its accurate linear measurements. But when it comes to automatic detection of voxel intensity values as in automatic nerve detection, little evidence in the literature was found. Thus; in order to examine the accuracy of this automatic process, this study was performed in vitro. Methods: A dry edentulous mandible was imaged using i-CAT next generation (Imaging sciences international, Hatfield, PA, USA) using gutta percha markers at certain areas of interest, the reconstructed panoramic image was evaluated and nerve tracing was done for both sides, then linear measurements was performed from the edge of the inferior alveolar nerve canal (IANC) to the inferior border of mandible, buccal, lingual and crest of the ridge. These measurements were compared to actual physical measurements performed by using a digital caliber after sectioning of the mandible at the gutta percha sites. Results: Intra-observer agreement was good to very good regarding all measurements for both observers, while inter observer agreement was weak to very good regarding all measurements for both observers. There was no statistically significant difference between the CBCT scans (0.2 mm, 0.3 mm, and 0.4 mm voxel size) regarding all measurements except one measurement at the 0.4 mm voxel size CBCT scan showed a statistically significant high mean error. Conclusion: The choice of FOV and voxel size should be made by clinicians based on the clinical task at hand, keeping in mind that their choices not only affect the diagnostic quality of images but also the amount of radiation exposure that their patients receive.

Objetivo: Identificar la relación entre la inclinación de la eminencia articular de pacientes clase II esquelética con signos de osteoartrosis, medidos con tomografía computarizada de haz cónico (TCHC) en pacientes del Centro de Diagnóstico por Imágenes (CDI) en Lima, Perú, entre los años 2010 y 2014. Materiales y método: El grupo de estudio retrospectivo será planificado de acuerdo con el tamano de muestra de estimación y consistirá en exploraciones con TCHC de pacientes asintomáticos; las imágenes serán obtenidas del archivo del CDI, previa solicitud al director. Las imágenes TCHC serán analizadas con el software RealScan 2.0 (Point Nix. Corea) para los defectos óseos mediante reconstrucción multiplanar en vistas axiales, coronales, sagitales, cortes transaxiales, así como la evaluación mediante reconstrucciones 3D en volumen rendering y para la inclinación de la eminencia articular, una de las vistas axiales sobre la cual se observan los procesos condilares en su más amplia extensión lateral medial y que es utilizada como vista de referencia para la reconstrucción secundaria. Resultados: El promedio de edad fue de 30 anos ± 6,13 y no hubo diferencias significativas entre sexos. El ángulo ANB en promedio la muestra fue de 7,02° ± 1,80° y no hubo diferencias significativas entre géneros. Los valores cuantitativos de la inclinación de la eminencia articular medidos a través de los ángulos EBT y ETR no tuvieron diferencias significativas entre lados. No se encontró asociación significativa entre el ángulo de la eminencia articular EBT y la presencia de cambios óseos degenerativos. En el caso de la asociación entre el grado del ángulo de la eminencia articular ETR y la presencia de cambios óseos degenerativos, el aplanamiento mostró del lado izquierdo y se encontró asociación significativa con la erosión en el lado derecho. Conclusiones: La inclinación de la eminencia articular medida en el ángulo EBT de pacientes clase II esquelética y su relación con cambios osteoatrósicos según lado no muestra asociaciones significativas. La inclinación de la eminencia articular medida en el ángulo ETR de pacientes clase II esquelética y su relación con cambios osteoartrósicos, según lado del aplanamiento, mostró una asociación significativa en lado izquierdo y una asociación significativa en la erosión del lado derecho.
