Relative frequency of dentigerous cyst in Iranian population: A 20-year retrospective study
Indian Journal of Dental Research, 2019 Purpose: Dentigerous cyst (DC) is the most common type of developmental odontogenic cysts which apparently develops via accumulation of fluid between the reduced enamel epithelium and crown of the tooth.

DeepDoseNet: A Deep Learning model for 3D Dose Prediction in Radiation Therapy [PDF]
arXiv, 2021 The DeepDoseNet 3D dose prediction model based on ResNet and Dilated DenseNet is proposed. The 340 head-and-neck datasets from the 2020 AAPM OpenKBP challenge were utilized, with 200 for training, 40 for validation, and 100 for testing. Structures include 56Gy, 63Gy, 70Gy PTVs, and brainstem, spinal cord, right parotid, left parotid, larynx, esophagus,

Advanced Healthcare Materials, EarlyView.In this study, a cuff‐free, less‐invasive surgical approach for vagus nerve stimulation (VNS) by combining ultrathin Y‐shaped kirigami electrodes is developed with a chemically cross‐linked hydrogel adhesive (hydrogel‐kirigami). Unlike conventional cuff implantation, which may damage nerves and nearby critical vessels, this new technique minimizes ...

Multifocal Central Giant Cell Granuloma - A Case Report [PDF]
Iranian Journal of Pathology, 2016 Central giant cell granuloma is a benign, aggressive neoplasm composed of multinucleated giant cells that almost exclusively occurs in the jaws though extra-gnathic incidence is rare.Multifocal CGCGs of the jaws are very rare and suggestive of systemic ...

Mandibular Implants: A Metamaterial‐Based Approach to Reducing Stress Shielding
Advanced Healthcare Materials, EarlyView.Metamaterial mandibular implants offer a novel approach to reducing stress shielding and enhancing biomechanical stimulation. This study compares a gyroid‐based metamaterial plate to a solid titanium plate using photoelasticity and finite element analysis.

Robust and fully automated segmentation of mandible from CT scans [PDF]
arXiv, 2017 Mandible bone segmentation from computed tomography (CT) scans is challenging due to mandible's structural irregularities, complex shape patterns, and lack of contrast in joints. Furthermore, connections of teeth to mandible and mandible to remaining parts of the skull make it extremely difficult to identify mandible boundary automatically.

Advanced Science, EarlyView.The study highlights the potential of recombinant galaxin (a coral protein) as a novel and effective biomaterial for bone regeneration. It binds to ATP synthase subunit β (ATP5B) in mouse pre‐osteoblasts, thereby causing increased ATP production and mitochondrial activity.

Robustness study of noisy annotation in deep learning based medical image segmentation [PDF]
arXiv, 2020 Partly due to the use of exhaustive-annotated data, deep networks have achieved impressive performance on medical image segmentation. Medical imaging data paired with noisy annotation are, however, ubiquitous, but little is known about the effect of noisy annotation on deep learning-based medical image segmentation.
