Development of the oxytalan fiber system in the periodontal space of rat incisors
Annals of Anatomy - Anatomischer Anzeiger, 2013The present study clarifies developmental organization of the oxytalan fiber system in the periodontal space of both the enamel (labial) and cementum (lingual) sides of rat incisors. The number of oxytalan fibers per unit area (μm(2)) was counted in rat incisors at stages of embryonic day 20 (E20) to postnatal day 35 (P35).

Fine structure of adrenergic nerve fibers in human periodontal ligament
Journal of Periodontal Research, 1992The presence of adrenergic nerve fibers was demonstrated ultrastructurally in the human periodontal ligament obtained from extracted premolar teeth from 8 young patients. The nerve endings were located close to arterioles. The results suggest that they seem to control blood flow in the human periodontal ligament.

Monolithic Tetracycline‐containing Fibers for Controlled Delivery to Periodontal Pockets
Journal of Periodontology, 1983For the purpose of developing controlled delivery devices for periodontal therapy which would release over several days, six fiber types made of tetracycline‐loaded biocompatible polymers were manufactured and tested. Polyethylene, polypropylene, polycaprolactone, polyurethane and cellulose acetate propionate all released their drug load within 1 day ...

The behavior of collagen fibers in some types of periodontal disease
Oral Surgery, Oral Medicine, Oral Pathology, 1953Abstract 1. 1. The etiology and pathogenesis of certain types of disease of the membrane and alveolar bone are discussed. 2. 2. Special reference is made to the possible physicochemical effects of abnormal masticatory forces and inflammatory gingival conditions on collagen fibers. 3. 3. The possible importance of the “adaptation syndrome”

Stretching modulates oxytalan fibers in human periodontal ligament cells
Journal of Periodontal Research, 2009Background and Objective: Oxytalan fibers, as well as collagen fibers, are the structural components of periodontal ligaments. Periodontal ligaments are continuously exposed to various functional forces. However, the behavior of oxytalan fibers under mechanical strain has not been investigated.

Collagen Fiber Architecture of the Periodontal Ligament in Equine Cheek Teeth
Journal of Veterinary Dentistry, 2006The objective of this study was to examine the spatial arrangement of the fiber apparatus of the equine periodontium which is supposed to meet two contrary requirements: (1) to attach the tooth firmly and elastically to the alveolar bone; and, to be appropriately remodeled and reconstructed in order to facilitate the prolonged eruption of the tooth ...

Tetracycline-Loaded Fibers as Adjunctive Treatment In Periodontal Disease
The Journal of the American Dental Association, 1994Fiber placed in periodontal pockets to deliver tetracycline continuously for 10 days was effective in reducing pocket depth and bleeding on probing when used as an adjunct to scaling and root planing. In this study, the combined therapy was valuable in treating adult patients who had refractory disease sites.

The Oxytalan Fiber System in the Mandibular Periodontal Ligament of the Lathyritic Mouse
Journal of Oral Pathology & Medicine, 1977Abstract Experimental lathyrism was produced in young albino mice with a diet containing 50 % sweet pea seed (Lathyrus odoratus). After 7 days on the lathyritic diet, sections of the mandibular molar and incisor periodontal ligaments, when oxidized and treated with aldehyde fuchsin, demonstrated enhanced staining of the oxytalan fibers and numerous ...

Response properties of periodontal mechanosensitive fibers in the superior dental nerve of the cat
Experimental Neurology, 1986Periodontal mechanosensitive units were detected as single nerve fibers from the anterior branches of five cats, and their receptive fields and optimal stimulus directions were examined. Of 801 units detected, 759 units (95%) responded to movement of only one tooth (single-tooth unit), and 42 units (5%) responded to movement of two or three teeth ...
