The Effect of Canal Contamination with Saliva on Apical Sealing

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2014
Introduction: Root canal obturation aims at sealing the root canal system to prevent re-contamination of canal and periapical space. Presence of moisture in canal before obturation may posit a negative effect on the quality of canal sealing.

Geometric Characterizations of Canal Hypersurfaces in Euclidean Spaces [PDF]

arXiv, 2021
In the present paper, firstly we obtain the general expression of canal hypersurfaces in Euclidean n-space and deal with canal hypersurfaces in Euclidean 4-space E4. We compute Gauss map, Gaussian curvature and mean curvature of canal hypersurfaces in E4 and obtain an important relation between the mean and Gaussian curvatures as 3Hrho = Krho^3-2.

Canals in Milky Way radio polarization maps [PDF]

Mon.Not.Roy.Astron.Soc.Lett. 371 (2006) L21-L25, 2006
Narrow depolarized canals are common in maps of the polarized synchrotron emission of the Milky Way. Two physical effects that can produce these canals have been identified: the presence of Faraday rotation measure ($\RM$) gradients in a foreground screen and the cumulative cancellation of polarization known as differential Faraday rotation.

Management of Six Root Canals in Mandibular First Molar

Case Reports in Medicine, 2015
Success in root canal treatment is achieved after thorough cleaning, shaping, and obturation of the root canal system. This clinical case describes conventional root canal treatment of an unusual mandibular first molar with six root canals. The prognosis

How does gender influence student learning, stress and career choice in endodontics?

International Endodontic Journal, EarlyView.
Abstract The influence of gender is underexplored in endodontic educational research. This review examines the effect of gender on learning within the domains of skill acquisition, performance and difficulties encountered. It also analyses the stress and confidence experienced by male and female students during clinical endodontics, as well as their ...

Therapeutic Irrigant Procedures for Treating Apical Periodontitis (TIPTAP): A triple‐blinded parallel‐group randomized controlled phase I/II trial

International Endodontic Journal, EarlyView.
Abstract Background Solubilized endogenous dentine extracellular matrix components (dECMs) are potent mediators in pulp regeneration and could potentially promote similar healing effects in diseased periradicular tissues by upregulating local mesenchymal stem cell‐derived regenerative events.

Comparative Analysis of Root Canal Filling Debris and Smear Layer Removal Efficacy Using Various Root Canal Activation Systems during Endodontic Retreatment

Medicina, 2020
Background and objectives: The complete removal of obturation material can be a challenge in nonsurgical root canal retreatment. The insufficient removal of obturation material is a reason for root canal retreatment failure.

A re‐usable 3D‐printed training model for the endodontic management of dental trauma in immature teeth

International Endodontic Journal, EarlyView.
Abstract Aim To develop a 3D‐printed model enabling treatment simulation of trauma‐related endodontic and restorative procedures like revitalization or placement of an apical plug on teeth with incomplete root formation. Methodology To generate a realistic training model suitable for trauma‐related simulations, CT‐Data sets were segmented, combined ...
