The Perspective Silhouette of a Canal Surface

Computer Graphics Forum, 2003
Abstract We present an efficient and robust algorithm for parameterizing the perspective silhouette of a canal surface and detecting each connected component of the silhouette. A canal surface is the envelope of a moving sphere with varying radius, defined by the trajectory C(t) of its center and a radius function

Surface Tension of Root Canal Irrigants

Journal of Endodontics, 2000
The aim of this study was to evaluate the surface tension values of established and potential endodontic irrigants to which a surface active agent had not been added. Additionally, Cetredixine, a surfactant-containing 0.2% chlorhexidine gluconate solution, was included in the measurements.

Computing the Distance between Canal Surfaces

2010
A canal surface is the envelope of a one-parameter set of moving spheres. We present an accurate and efficient method for computing the distance between two canal surfaces. First, we use a set of cone-spheres to enclose a canal surface. A cone-sphere is a surface generated by sweeping a sphere along a straight line segment with the radius of the sphere
