The relation between parameter curves and lines of curvature on canal surfaces [PDF]

open access: yesarXiv, 2012
A canal surface is the envelope of a moving sphere with varying radius, defined by the trajectory C(t) (spine curve) of its center and a radius function r(t). In this paper, we investigate when parameter curves of the canal surface are also lines of curvature. Last of all, for special spine curves we obtain the radius function of canal surfaces.

Assessment of Root Canal Filling Capacity and Quality of the Root Canal Pastes

open access: yesActa Stomatologica Croatica
Background: The complex anatomy of root canals in primary teeth makes root canal treatment and canal filling difficult. Root canal filling materials should meet the basic requirements for hermetic filling in terms of their physicochemical properties ...

Cross-Frequency Collaborative Training Network and Dataset for Semi-supervised First Molar Root Canal Segmentation [PDF]

open access: yesarXiv
Root canal (RC) treatment is a highly delicate and technically complex procedure in clinical practice, heavily influenced by the clinicians' experience and subjective judgment. Deep learning has made significant advancements in the field of computer-aided diagnosis (CAD) because it can provide more objective and accurate diagnostic results.

Stratification and enumeration of Boolean functions by canalizing depth [PDF]

open access: yesarXiv, 2015
Boolean network models have gained popularity in computational systems biology over the last dozen years. Many of these networks use canalizing Boolean functions, which has led to increased interest in the study of these functions. The canalizing depth of a function describes how many canalizing variables can be recursively picked off, until a non ...

Impact of Delayed Completion of Previously Initiated Therapy and Provider Type on Outcomes of Root Canal Treatment [PDF]

open access: yes, 2020
Objective:if the provider type influences long-term outcomes in instances where NSRCT has been previously initiated. The primary purpose of this study was to determine if the period of time between previously initiated therapy and the completion of non ...

Two Rooted Mandibular First Molar with Three Distal Canals - A Case Report

open access: yesAdvances in Human Biology, 2014
Background: The Mandibular first molar is the tooth that requires root canal treatment most often. It usually has two roots with two canals mesially and one or two canals distally.
