ENDODONTIC TREATMENT OF LOWER LATERAL INCISOR WITH THREE ROOT CANALS – CASE REPORT. [PDF]

Journal of IMAB, 2013
The main goal of endodontic treatment is the correct diagnosis, optimal mechanical and chemical preparation and three-dimensional obturation of the root canal. Reasons for endodontic failure can be variations in the anatomy of the teeth - the presence of

The Short Apical Membrane Half-life of Rescued ΔF508-Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) Results from Accelerated Endocytosis of ΔF508-CFTR in Polarized Human Airway Epithelial Cells [PDF]

Journal of Biological Chemistry, 2005
The most common mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene in individuals with cystic fibrosis, DeltaF508, causes retention of DeltaF508-CFTR in the endoplasmic reticulum and leads to the absence of CFTR Cl(-) channels in the apical plasma membrane.

Quantitative Evaluation of Apical Delta Morphologies in Mesial Roots of Mandibular First Molar Teeth: A Micro-CT Study

Turkiye Klinikleri Journal of Dental Sciences, 2017
Objective: The apical delta is the branching of the main root canal dividing into three or more ramifications near the root apex, while the main canal itself becoming indistinguishable. Aim of this study was to analyze apical delta morphologies of mesial root canals of mandibular first molar teeth quantitatively using micro--computed tomography (micro--
