Quality assurance dosimetry often requires the comparison of measured doses with those calculated by a treatment-planning system for phantoms of density other than 1.000 g/cm3. The presence of an artifact in the Pinnacle3 treatment-planning system can lead to systematic errors in such cases. These errors are also present, although reduced in magnitude, in heterogeneous media.

Background Orthodontic diagnostic workflows often rely on manual classification and archiving of large volumes of patient images, a process that is both time-consuming and prone to errors such as mislabeling and incomplete documentation. These challenges can compromise treatment accuracy and overall patient care. To address these issues, we propose an artificial intelligence (AI)-driven deep learning framework based on convolutional neural networks (CNNs) to automate the classification and archiving of orthodontic diagnostic images.

Purpose: This study aimed to provide quantitative information for implementing Lattice radiotherapy (LRT) using a medical linear accelerator equipped with the Millennium 120 multi-leaf collimator (MLC). The research systematically evaluated the impact of varying vertex diameters and separations on dose distribution, peak-to-valley dose ratio (PVDR), and normal tissue dose.
Methods: A cylindrical Virtual Water™ phantom was used to create LRT treatments using the Eclipse version 16.

Oral and maxillofacial diagnostic imaging is of paramount importance in dental clinical diagnosis, treatment planning, and follow-up procedures. Periapical radiographic examination and numerous panoramic systems are used in routine clinical dental practice. Cone beam CT is widely used and currently the method of choice in oral and maxillofacial implantology, endodontics, maxillofacial surgery, periodontics, degenerative temporomandibular joint disease, orthodontics, airway studies, sleep disorders, and forensic dentistry.

Objective: This case report demonstrates the orthodontic treatment to correct a severe scissor bite and occlusal disharmony in a 26-year-old female patient, including the use of temporary anchorage devices (TADs) and fixed orthodontic appliances.
Clinical Considerations: Severe scissor bite is associated with vertical problems, such as molar extrusion. For orthodontic treatment, interradicular TADs were used to intrude the extruded molars, control the inclination of molars, correct dental midline, and improve dental relationships.

Introduction And Aim: The assessment of gingival inflammation surface features mainly depends on subjective judgment and lacks quantifiable and reproducible indicators. Therefore, it is a need to acquire objective identification information for accurate monitoring and diagnosis of gingival inflammation. This study aims to develop an automated method combining intraoral scanning (IOS) and deep learning algorithms to identify the surface features of gingival inflammation and evaluate its accuracy and correlation with clinical indicators.
