Panoramic radiography and cone-beam computed tomography to measure distances between root apexes and anatomical structures

open access: yesJournal of Oral Research, 2022
Aim: To compare the accuracy of the panoramic radiography with cone-beam computed tomography (CBCT) scans in measuring the distances between root apexes and the adjacent anatomical structures including the maxillary sinus and the mandibular canal ...

Panoramic ghosts

open access: yesOral Surgery, Oral Medicine, Oral Pathology, 1987
The panoramic artifact of ghost images is discussed and explained. The three-dimensional area within which an object must be to produce a ghost image is depicted for three panoramic machines. The radiographic features of ghosts and the objects or anatomic structures that cause them are listed.

Rara Avis: Stafne’s Bone Cyst of Mandible—A Case Report [PDF]

open access: yesDental Journal of Advance Studies, 2023
Stafne’s bone cyst (SBC) are static lesions that are commonly located at the angle of the mandible. Males are affected more as compared with females with an incidence ranging from 0.10% to 0.48%. Stafne bone cysts are usually asymptomatic.

Deep Learning for the Radiographic Detection of periodontal Bone Loss [PDF]

open access: yes, 2019
We applied deep convolutional neural networks (CNNs) to detect periodontal bone loss (PBL) on panoramic dental radiographs. We synthesized a set of 2001 image segments from panoramic radiographs. Our reference test was the measured % of PBL.

Forensic Gender Determination by Using Mandibular Morphometric Indices an Iranian Population: A Panoramic Radiographic Cross-Sectional Study

open access: yesJournal of Imaging, 2023
Gender determination is the first step in forensic identification, followed by age and height determination, which are both affected by gender. This study assessed the accuracy of gender estimation using mandibular morphometric indices on panoramic ...

Panoramic Coronary Angiography

open access: yesJournal of the American College of Cardiology, 1998
We describe a new imaging technique for coronary angiography.The conventional approach to coronary angiography exploits static perspective imaging over multiple cardiac cycles, using a limited number of empirically selected views. This approach entails both lack and redundancy of information and may result in suboptimal visualization of the individual ...

Evaluation of panoramic digital images using Panoptiq for frozen section diagnosis

open access: yesJournal of Pathology Informatics, 2016
Introduction: Whole slide imaging (WSI) permits intraoperative consultations (frozen sections) to be performed remotely. However, WSI files are large and can be problematic if there are tissue artifacts (e.g., tissue folds) or when slides are scanned ...

Reactive direction control for a mobile robot: A locust-like control of escape direction emerges when a bilateral pair of model locust visual neurons are integrated [PDF]

open access: yes, 2010
Locusts possess a bilateral pair of uniquely identifiable visual neurons that respond vigorously to the image of an approaching object. These neurons are called the lobula giant movement detectors (LGMDs). The locust LGMDs have been extensively studied

The Relationship between Birth Weight, Birth Height, and Dental Development by Demirjian’s Method [PDF]

open access: yesJournal of Dental Materials and Techniques, 2013
Introduction: Like other measures of human development, dental development is not in complete accordance to chronological age. Investigations show that dental age can be affected by gender, race, systemic conditions, and some other factors and ...
