| root canal preparation | Preparatory activities in root canal therapy by partial or complete extirpation of diseased pulp, cleaning and sterilization of the empty canal, enlarging and shaping the canal to receive the sealing material. The cavity may be prepared by mechanical, sonic, chemical, or other means. (12 Dec 1998) |

| root canal therapy | A treatment modality in endodontics concerned with the therapy of diseases of the dental pulp. For preparatory procedures, root canal preparation is available. (12 Dec 1998) |
| root canal treatment | The means by which painful or diseased teeth, in which the pulp is involved, are restored to a healthy state, removal of a normal, diseased, or dead pulp by biochemical and mechanical means, enlargement and sterilization of the root canal, followed by filling the canal, to effect healing of diseased periapical tissues, the diagnosis and treatment of diseases of the pulp and their sequelae. Synonym: endodontic treatment. (05 Mar 2000) |
| root cap | <botany> A mass of parenchymtous cells which covers and protects the growing cells at the end of a root; a pileorhiza. The issue found at the apex of roots, overlying the root apical meristem and protecting it from friction as the root grows through the soil. Secretes a glycoprotein mucilage as a lubricant. (18 Nov 1997) |

| root filaments | The small, individual fibre fascicles into which the roots of all of the spinal nerves and several cranial nerves (hypoglossus, vagus, oculomotorius) divide in fanlike fashion before entering or leaving the spinal cord or brainstem; the spinal dorsal root may divide into 8 to 12 such rootlets. Synonym: fila radicularia, root filaments. (05 Mar 2000) |

| root hair cell | <botany> Root epidermal cell, part of which projects from the root surface as a thin tube, thus increasing the root surface area and promoting absorption of water and ions. (18 Nov 1997) |
