Comparison of automatic and visual methods used for image segmentation in Endodontics: a microCT study

Journal of Applied Oral Science
To calculate root canal volume and surface area in microCT images, an image segmentation by selecting threshold values is required, which can be determined by visual or automatic methods. Visual determination is influenced by the operator's visual acuity,

Characterization of an Injectable Poly(vinyl alcohol)‐gelatin Hydrogel for Growth Factor Delivery in an Orthopedic Application

Advanced Healthcare Materials, EarlyView.
This work introduces photo‐crosslinkable tyraminated poly(vinyl alcohol)‐gelatin (PVA‐GT) hydrogels as tunable injectable platforms for tissue engineering and growth factor delivery applications. This schematic illustrates the two developed hydrogel formulations and the experimental workflow used to evaluate their physico‐chemical properties in vitro ...

On canal surfaces in E3

, 2010
In this paper we deal with the geometric properties of canal surfaces in E. Further, the first and second fundamental form of canal surfaces are presented. By the use of the second fundamental form, the Gaussian and mean curvature of canal surfaces are obtained. Finally, the visualization of canal surfaces which their spine curves are unit circle and a

Increased stiffness and flow resistance of the inner wall of Schlemm’s canal in glaucomatous human eyes

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Glaucoma is a leading cause of irreversible blindness. The elevated intraocular pressure that is characteristic of primary open-angle glaucoma is due to increased resistance to aqueous humor outflow.
