Primary intraosseous carcinoma of mandible

open access: yesJournal of Indian Academy of Oral Medicine and Radiology, 2009
Primary intraosseous carcinoma (PIOC) is a rare malignant neoplasm of the jaw which is locally aggressive with poor prognosis. These tumors are believed to arise from the odontogenic epithelium and hence are referred to as odontogenic carcinomas.

Recurrent convolutional neural networks for mandible segmentation from computed tomography [PDF]

open access: yesarXiv, 2020
Recently, accurate mandible segmentation in CT scans based on deep learning methods has attracted much attention. However, there still exist two major challenges, namely, metal artifacts among mandibles and large variations in shape or size among individuals.

Prediction of mandibular ORN incidence from 3D radiation dose distribution maps using deep learning [PDF]

open access: yesarXiv, 2021
Background. Absorbed radiation dose to the mandible is an important risk factor in the development of mandibular osteoradionecrosis (ORN) in head and neck cancer (HNC) patients treated with radiotherapy (RT). The prediction of mandibular ORN may not only guide the RT treatment planning optimisation process but also identify which patients would benefit

Mandible-Powered Escape Jumps in Trap-Jaw Ants Increase Survival Rates during Predator-Prey Encounters

open access: yesPLoS ONE, 2015
Animals use a variety of escape mechanisms to increase the probability of surviving predatory attacks. Antipredator defenses can be elaborate, making their evolutionary origin unclear.

From Mechanoelectric Conversion to Tissue Regeneration: Translational Progress in Piezoelectric Materials

open access: yesAdvanced Materials, EarlyView.
This review highlights recent progress in piezoelectric materials for regenerative medicine, emphasizing their ability to convert mechanical stimuli into bioelectric signals that promote tissue repair. Key discussions cover the intrinsic piezoelectric properties of biological tissues, co‐stimulation cellular mechanisms for tissue regeneration, and ...

Is cone-beam computed tomography diagnostic for anterior Stafne bone cyst: Report of a rare case

open access: yesDental Hypotheses, 2015
Introduction: The incidence of anterior Stafne bone cyst (lingual mandibular bone defect, static bone cyst, latent bone cyst, developmental submandibular gland defect of the mandible) has been estimated to between 0.009% and 0.3%.

Smooth Extrapolation of Unknown Anatomy via Statistical Shape Models [PDF]

open access: yesIn Medical Imaging 2015: Image-Guided Procedures, Robotic Interventions, and Modeling 2015 Mar 18 (Vol. 9415, p. 941524). International Society for Optics and Photonics, 2019
Several methods to perform extrapolation of unknown anatomy were evaluated. The primary application is to enhance surgical procedures that may use partial medical images or medical images of incomplete anatomy. Le Fort-based, face-jaw-teeth transplant is one such procedure. From CT data of 36 skulls and 21 mandibles separate Statistical Shape Models of
