3-Dimensional Analysis and Systematic Review of Root Canal Morphology and Physiological Foramen Geometry of 109 Mandibular First Premolars by Micro-computed Tomography in a Mixed Swiss-German Population.
Abstract Introduction The aim of this study was to systematically revise the root canal configuration (RCC) literature and to investigate the root canal morphology of mandibular first premolars (Ma1Ps) of 2 populations by means of micro–computed tomographic imaging. Methods This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines including RCC randomized controlled trials and cross-sectional, cohort, comparative, validation, and evaluation studies. Furthermore, the RCC, physiological foramina, the frequency of accessory and connecting canals, and the physiological foramina morphology of 109 Ma1Ps were investigated by means of micro–co…
An Ex Vivo Study of Root Canal System Configuration and Morphology of 115 Maxillary First Premolars
Abstract Introduction The aim of this study was to investigate the root canal system morphology of maxillary first premolars by means of micro–computed tomographic imaging in a Swiss-German population. Methods The root canal configuration (RCC) of 115 maxillary first premolars (Mx1Ps) were investigated by means of micro–computed tomographic imaging and 3-dimensional imaging. The RCC and the physiological foramina results are described by a 4-digit system code. Results Twelve different RCCs were observed in 30 single-rooted Mx1Ps; 2-2-2/2 (30.0%), 1-2-2/2 (13.3%), 1-2-1/2 (10%), and 2-2-1/2 (10.0%) were the most frequent ones. Seven different RCCs were observed in 2-rooted Mx1Ps (n = 81) in …
