Root Canal System and Morphology of Mandibular Second Molar Using Cone Beam Computed Tomography [PDF]

open access: yes, 2020
Objective: As human 2nd molar teeth demonstrate considerable anatomic complexities and abnormalities in the number of roots and root canals, this study aimed to determine and investigate the root canal system of the mandibular 2nd molar teeth of a sample

Root photomorphogenesis in laboratory-maintained Arabidopsis seedlings [PDF]

open access: yes, 2013
In nature, root systems of most terrestrial plants are underground in darkness. Nevertheless, several photoreceptors have been found in roots and light-responsive mechanisms allowing roots to escape from strong light conditions have been discovered.

Insight into the early steps of root hair formation revealed by the procuste1 cellulose synthase mutant of Arabidopsis thaliana [PDF]

open access: yes, 2008
Background: formation of plant root hairs originating from epidermal cells involves selection of a polar initiation site and production of an initial hair bulge which requires local cell wall loosening. In Arabidopsis the polar initiation site is located

Morphological Studies on the Root

open access: yesJapanese Journal of Oral Biology, 1979
Root concavity are always in evidence at the root surfaces of lower premolar, arenoted for a long time. The frequency of the concavity was different with the kinds of teeth andthe mesio-distal and bucco-lingual surface. The concavity on the mesial surface of lower firstpremolar and the buccal surface of lower second premolar are widely noted.One ...

Response-based selection of barley cultivars and legume species for complementarity : root morphology and exudation in relation to nutrient source [PDF]

open access: yes, 2017
Phosphorus (P) and nitrogen (N) use efficiency may be improved through increased biodiversity in agroecosystems. Phenotypic variation in plants’ response to nutrient deficiency may influence positive complementarity in intercropping systems.

Evaluation of root and canal morphologies of permanent canines in a Saudi Arabian sub population using cone-beam computed tomography

open access: yesJournal of Dental Sciences, 2022
Background/purpose: Failure to identify and treat the root canal system in its entirety has been known to be one of the leading causes of unsuccessful root canal treatment (RCT).
