Anatomy of the lumbar radicular canal

Anatomia Clinica, 1983
The radicular canal is defined as the lateral part of the spinal canal containing the spinal nerve root from its point of emergence through the dural envelope up to and including the intervertebral foramen. The radicular canal, resembling a hollow hemicylinder opened towards the midline, can be divided into three parts, i.e. retrodiscal, parapedicular (

Root and canal morphology of mandibular first premolars with radicular grooves

Archives of Oral Biology, 2013
To investigate the relation between the radicular groove (RG) and the internal root canal morphology in mandibular first premolars by using micro-computed tomography.A total of 249 extracted mandibular first premolars were collected from a native Chinese population.

Micro–computerized tomographic analysis of radicular and canal morphology of premolars with long oval canals

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2008
The aims of this in vitro study were to measure root and canal diameters, root and canal diameter ratios, mean taper of the root canal and of each root canal section, and radicular wall thickness at different levels in premolars with long oval root canals.Thirty human premolars, with single long oval canals were selected for this study.

Bonding of Self-adhesive (Self-etching) Root Canal Sealers to Radicular Dentin

Journal of Endodontics, 2009
The latest generation of methacrylate resin-based sealers has eliminated the use of separate self-etching primers by incorporating acidic resin monomers in the sealers to render them self-adhesive to dentin. This study examined the adhesive strengths, interfacial ultrastructure, and tracer penetration of a nonetching (EndoREZ; Ultradent, South Jordan ...

Anatomy and radiological anatomy of the lumbar radicular canals

Anatomia Clinica, 1984
The radicular canal is the lateral portion of the spinal canal when it is trefoil. It is a bony and ligamentary, monovertebral and indeformable space, the measurements of which are reproducible. The anatomy of this radicular canal has been studied in the whole of the lumbar vertebrae of 50 anatomical subjects.

Narrow Radicular Canal

1980
Between 1949 and 1954, Verbiest described a new etiology of cauda equina compression of spinal origin, namely, the developmental or dysplastic lumbar spinal canal. The shortness of the pedicles and the dysmorphic thickness of the laminae result in a reduction of the anteroposterior diameter of the lumbar canal. This author measures the canalar diameter

Extra-radicular Causes of Root Canal Failure: A Review

International Journal of Dental Health Concerns, 2015
It is usually believed that root canal therapy fails because of failure to follow treatment protocols. However, sometimes even after following the highest standards of treatment the outcome of the therapy is not good. The cause for this might be intra radicular or extra radicular. Clinicians mostly concern themselves with the root canal only and forget

[Segmentation of the lumbar radicular canal].

Neuro-Chirurgie, 1986
The lumbar CT horizontal sections identification requires three levels to be defined of each vertebra: The arthropedicular level (upper third) describes an (omega) at the back with its dense bone structures. At each side of the canal is the upper part of the lateral recess, the narrowest and therefore the most threatened part of the nerve root passage.

Radicular Groove Accessory Canal Morphology in Mandibular First Premolars: Micro–computed Tomographic Study

Journal of Endodontics, 2019
The purpose of this study was to investigate the morphologic features of radicular groove accessory canals (RGACs) in mandibular first premolars and their relationship to root anatomy by micro-computed tomographic imaging.A total of 154 single-rooted mandibular first premolars with radicular grooves were selected.
