Digital Panoramic Radiography in Dental Age Estimation

Biointerface Research in Applied Chemistry, 2020
The present study aimed to assess the validity of coronal pulp/tooth area ratio (AR) and tooth/coronal index (TCI) indices in the mandibular first molar and second premolar for age estimation.110 digital panoramic radiographs of 60 male and 50 female subjects aged between 15 to 44 years were studied.

Clinical outcomes of a novel flowable calcium silicate cement in equine endodontic treatment

Equine Veterinary Journal, EarlyView.
Abstract Background Orthograde endodontic treatment of equine cheek teeth is performed infrequently with variable success rates of obturation with calcium hydroxide paste (CHP). A novel flowable calcium silicate cement (eCSC) formulated for use as an obturation material in equine teeth has demonstrated acceptable canal filling volumes and evidence of ...

Visualization of Scattered Tumor Regression Following Neoadjuvant Chemoimmunotherapy With a Novel Intraoperative PET/CT Scanner

Head &Neck, EarlyView.
ABSTRACT Background Neoadjuvant chemoimmunotherapy is being explored in locally advanced head and neck squamous cell carcinoma (HNSCC), yet the spatial patterns of pathologic response and clinical implications remain poorly characterized. Methods A 79‐year‐old female with recurrent left oral tongue SCC (PD‐L122C3 Combined Positive Score 90) who ...

Augmented Reality of Anatomical Structures of the Maxillomandibular Complex for Learning Dental Radiographic Techniques

Journal of Dental Education, EarlyView.
ABSTRACT Introduction Augmented reality (AR) enables interactive learning in real‐world environments. In dental radiography education, AR offers a promising tool to enhance students' clinical skills by allowing them to simulate and practice procedures before engaging with actual patients. Repeated practice in an AR environment can reinforce theoretical

The perceptibility curve test applied to direct digital dental radiography

Dentomaxillofacial Radiology, 1998
OBJECTIVE To compare the effect of an additional scintillator layer on the psychophysical properties of a CCD detector for digital dental radiography. METHODS Radiographs of a test object containing ten holes of increasing depth were obtained throughout the exposure range of two CCD detectors at 70 and 90 kVp.

Evaluation of Panoramic Acquisition Errors by Predoctoral Dental Students

Journal of Dental Education, EarlyView.
Abstract Objectives Panoramic radiography is commonly used in the management of dental‐alveolar pathology. Novice clinicians are prone to technical errors that diminish the diagnostic quality of radiographs. The objective of this study was to analyze technical errors made during panoramic exposures by third‐year (D3) dental students in order to enhance
