Evaluation of three obturation techniques in the apical third of mandibular first molar mesial root canals using micro-computed tomography

Journal of Dental Sciences, 2016
Background/purpose: Recent studies have demonstrated a high incidence of isthmuses in mandibular first molar mesial roots, and intratubular mineralization following mineral trioxide aggregate obturation.

Intrinsic Gaussian processes on complex constrained domains [PDF]

, 2018
We propose a class of intrinsic Gaussian processes (in-GPs) for interpolation, regression and classification on manifolds with a primary focus on complex constrained domains or irregular shaped spaces arising as subsets or submanifolds of R, R2, R3 and ...

Time‐Dependent Debridement Quality of the SAF Infinitum System in Flat‐Shaped Root Canals

International Endodontic Journal, EarlyView.
ABSTRACT Aim To evaluate the shaping ability, debris removal efficiency and morphological alterations induced by the SAF Infinitum system during progressive instrumentation of flat‐shaped root canals of mandibular incisors. Methodology Twelve extracted mandibular incisors with flat‐shaped canals were selected using micro‐CT and instrumented with 1.5‐mm

Microscopic Isthmuses and Fibrosis Within the Border Zone of Infarcted Hearts Promote Calcium-Mediated Ectopy and Conduction Block

Frontiers in Physics, 2018
Ventricular tachycardia (VT) secondary to myocardial infarction (MI) remain a major cause of sudden death in adults. Premature ventricular complexes (PVCs), the first initiating beats of a portion of these arrhythmias, arise from triggered activity in ...

Triple Loop Atrial Flutter Occurring After a Lung Transplant. [PDF]

J Arrhythm
High‐density activation mapping with a multipolar catheter revealed a triple loop atrial flutter occurring after a lung transplant in which two electrical connections between the recipient left atrium and the donor left pulmonary vein cuff and a surgical scar at the mitral isthmus acted as a substrate.

Thyroid isthmus agenesis

Medical Journal of Dr. D.Y. Patil University, 2015
The thyroid gland is the largest of all endocrine glands and is placed anteriorly in the lower neck in level with fifth cervical and first thoracic vertebrae. It is "H" shaped with two large lateral lobes, connected by a narrow isthmus in the midline. The gland bears very important clinical significance; both physiologically and pathologically and; a ...

Bachmann's Bundle‐Related Atrial Tachycardias Following Catheter Ablation of Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Atrial tachycardias (AT) after radiofrequency ablation (RFA) of atrial fibrillation (AF) may utilize Bachmann's bundle (BB). Due to their epicardial location, these ATs remain poorly understood. Objective To describe the electrophysiologic and anatomic basis of BB‐related ATs.
