Article Abstract
Objective: The aim of this study was to evaluate the impact of a 3D-printed model with simulated oral changes on the teaching of radiographic evaluation.
Methodology: A model of an adult patient with several simulated alterations was designed, including impacted teeth, dentigerous cyst, mesiodens, coronal fractures, periodontal resorptions, periapical lesions, and exostoses. The radiographic images obtained were evaluated by postgraduate students using a questionnaire. The data obtained were analyzed with descriptive and inferential statistics.
Results: The 3D model produced satisfactory images for the simulation of the proposed alterations. The general perception of the participants was positive, but there were significant differences between master's and doctoral students regarding the clinical-radiographic relationship of the simulated changes in general (p = 0.037) and the radiographic image of impacted canine (p = 0.032).
Conclusions: The 3D model was positively evaluated in most of the simulated alterations, demonstrating its potential as a pedagogical tool. These results reinforce the feasibility of 3D printing for producing models for radiographic assessment, offering image quality and versatility for the development of complex training.
Advances In Knowledge: This is the first study to develop and evaluate a 3D-printed model with complex anatomical and pathological alterations for preclinical training in Oral and Maxillofacial Radiology.

Geometric changes in the sigmoid sinus diverticulum (SSD) can alter its hemodynamic - a primary factor contributing to pulsatile tinnitus (PT). However, not all SSD cases lead to clinical PT symptoms. This study aims to investigate the influence of the diameter of the diverticulum (EDD) on the hemodynamics of the sigmoid sinus in PT.

Introduction: The conventional pin and tension band wiring (TBW) technique remains the standard for fixation, but is frequently associated with complications such as wire breakage, loosening, and delayed healing in patellar fracture. Locking plate fixation has demonstrated superior biomechanical stability in human studies. This study aimed to compare the biomechanical performance of locking plate fixation versus TBW in canine transverse patellar fractures and to evaluate the influence of plate design on fixation strength.

Fast and early detection of low-dose chemical toxicity is a critical unmet need in toxicology and human health, as conventional 2D culture models often fail to capture subtle cellular responses induced by sub-toxic exposures. Here, we present a bioengineered three-dimensional (3D) electrospun nanofibrous scaffold composed of polycaprolactone that enhances chromatin accessibility and primes fibroblasts for improved sensitivity to low-dose chemical stimuli in a short period. The scaffold mimics the extracellular matrix, providing topographical cues that reduce cytoskeletal tension and promote nuclear deformation, thereby increasing chromatin openness.

Background: Integrated mode proton imaging is a clinically accessible method for proton radiographs (pRads), but its spatial resolution is limited by multiple Coulomb scattering (MCS). As the amplitude of MCS decreases with increasing particle charge, heavier ions such as carbon ions produce radiographs with better resolution (cRads). Improving image resolution of pRads may thus be achieved by transferring individual proton pencil beam images to the equivalent carbon ion data using a trained image translation network.

Introduction: anatomical deformities such as developmental dysplasia of the hip (DDH) and Perthes disease represent a challenge for reconstruction. The use of 3D-printed models can be helpful for assessing the deformity, bone mass, implant size, and orientation.
Objectives: to prospectively evaluate the outcomes of 3D simulation in primary total hip arthroplasty.
