Root canal morphology of mandibular incisors
Journal of Endodontics, 1992In this study, 100 mandibular central and lateral incisors were used to determine the number of root canals and their types, the ramifications of the root canal, the location of apical foramina, and the frequency of apical deltas. The teeth were immersed in India ink, decalcified, and cleared.

Root and canal morphology of maxillary premolars and their relationship with the crown morphology
Journal of Oral Biosciences, 2022To investigate the relationship between crown/root size and root/canal morphology of maxillary premolars.One hundred and thirty-three first (P1) and 110 second (P2) maxillary premolars were used. Mesiodistal and buccolingual diameters and root heights of P1 and P2 were recorded to the nearest 0.01 mm. The number of single and multi-rooted premolars was

Identification of root morphology mutants in barley
Plant Genetic Resources, 2011In this study, a forward-genetics analysis was performed on a portion of TILLMore, a chemically mutagenized population of barley cv. ‘Morex’ (http://www.distagenomics.unibo.it/TILLMore/), to identify root morphology alterations by comparison with ‘Morex’ wild-type.

Morphology of cochlear root neurons in the rat
Journal of Neurocytology, 1988The morphology of large neurons in the cochlear nerve root of albino rat has been studied with a variety of techniques including Nissl and cell-myelin staining, Golgi impregnation, horseradish peroxidase back-filling of severed axons, transmission electron microscopy, and morphometry.

Root canal morphology of maxillary premolars
Journal of Endodontics, 1998The objective of this study was to investigate further internal anatomy of maxillary premolars. Six hundred recently extracted maxillary first and second premolar teeth were used in this study. One-half of the teeth were maxillary first premolars, the other half were maxillary second premolars.

Root morphology and development
Journal of Plant Nutrition, 1992Abstract Roots have been intensively studied for over one hundred years, and yet little is really known of their morphology and development in vivo. Increasing evidence suggests that there are five or more types of roots, each with distinct genetic, developmental, and physiological characteristics.

Morphological anatomy of thoracolumbar nerve roots and dorsal root ganglia
European Journal of Orthopaedic Surgery & Traumatology, 2017The aim of this study is to ascertain the anatomic parameters of the spinal roots and dorsal root ganglia and to demonstrate their clinical significance. Samples from 24 adult autopsy subjects were obtained from roots and dorsal root ganglia at levels L1 through L5.

Root length, crown height, and root morphology in Turner syndrome
Acta Odontologica Scandinavica, 1994Root length, crown height, and root morphology were studied on intraoral and panoramic radiographs in 33 Turner syndrome patients aged 7.0-16.7 years, subdivided on the basis of karyotype. Thirty-three normal girls aged 10.2-16.4 years served as controls.

The Motivation for Roots in Distributed Morphology
Annual Review of Linguistics, 2021Within Distributed Morphology, it has been proposed that the lexical vocabulary consists of Roots: category-less primitives. The motivation for Roots is connected with a line of argument reaching back to Chomsky's “Remarks on Nominalization” concerning the representation of lexical categories and their role in syntax.

The Morphology of Root Tubercles of Leguminosae
The American Naturalist, 1893The object of this research was to give a more detailed account of the anatomical structure of root tubercles, thus adding perhaps somewhat toward clearing up some of the difficulties in the comparatively little known field of teratology. It is true much labor has been expended in the endeavor to get a correct understanding of " symbiosis " and the ...
