Topic: Periodontium

  Endodontic-Periodontal Relations
HE HEALTH of the periodontium is important to the proper function of a tooth.
Disease that affects the periodontium usually is a result of the direct extension of pulpal disease or due to apical progression of periodontal disease.
The effect of periodontal disease on the pulp is not as clear-cut as the effect of pulpal disease on the periodontium.

 The application of bone morphogenetic proteins to dental tissue engineering - Nature Biotechnology   (Site not responding. Last check: 2007-10-21)
To induce morphogenesis of the teeth and periodontium, these elements must be combined to facilitate a developmental cascade of pattern formation, craniofacial plan establishment and the creation of the mirror-image bilateral symmetry of teeth in maxilla and mandible.
The tooth is surrounded by the periodontium and is anchored in the alveolar bone of the maxilla or mandible.
In addition, the periodontium is enriched in matrix metalloproteinases and may be detrimental to the inductive signals, including morphogens and growth factors, responding stem cells and scaffolds.

 Electrical stimulation dental device - Patent 4244373
Alternately, or in combination, the effect on the diseased tissue may be the increase in the circulation and the fluid level of the infected cells which may then cause absorbtion and elimination of the infected tissue cells.
It is believed that this principle is applicable to the generation of osteogenesis and chondrogenesis in periodontium areas within the mouth of the patient when the current is brought into the direct contact with the gingivae lining.
In this embodiment, first clamping dental device 20 is mounted on opposing transverse sides of the gingivae lining as is seen, is arcuate in contour passing in a coincident direction defined by a contour of the gingivae lining of the patient.

 Research - Peridontium
Following his training as a periodontist, Dr. Diekwisch was interested in the development of the periodontium ever since he started his first laboratory at the Philipps-University of Marburg in West Germany.
These data were supported by the discovery of massive migratory events that may be responsible for the formation of the mammalian periodontium (Diekwisch 2002).
During late stages of tooth development, the developing periodontium is a highly dynamic environment.

 Dorlands Medical Dictionary
(per”e-o-don-ti´tis) [peri- + odont- + -itis] inflammatory reaction of the tissues surrounding a tooth (periodontium), usually resulting from the extension of gingival inflammation (gingivitis) into the periodontium.
Periodontium, showing the periodontal ligament attaching the cementum of the tooth root to the alveolar bone of the socket; the collagen fibers of the ligament are grouped into bundles.
(per”e-o-don-tol´ə-je) [peri- + odont- + -logy] the branch of dentistry that deals with the scientific study of the structures and function of the periodontium in health and disease; broader in scope than periodontics, which is limited to the diagnosis, prevention, and treatment of periodontal disease, although the two terms are sometimes used interchangeably.

 Periodontium - Wikipedia, the free encyclopedia
This includes stratified squamous epithelium, connective tissues of basement membrane, ligaments, and alveolar bone.
The following tissues are part of the periodontium:
The word comes from the Greek terms "peri" meaning around and "odons" meaning tooth.

 Correlation between Tooth Mobility and Occlusion
Occlusal trauma is described as trauma to the periodontium from functional or parafunctional forces causing damage to the attachment apparatus of the periodontium by exceeding its adaptive and reparative capacities.
Consequently, occlusal forces which might otherwise be well tolerated in a healthy periodontium, now have deleterious effects because of preexisting periodontal disease.
Factors such as the frequency, duration, and velocity of those occlusal forces, not just their magnitude, may be of greater significance in the development of tooth hypermobility.

 Vrije Universiteit Amsterdam: Bioengineering of Bone and Periodontium
The program “Bioengineering of Bone and Periodontium” studies three sets of factors involved in regeneration of bone and periodontium: mechanical stress, growth factors, and graft materials.
They are involved in fracture repair and in the regulation of normal bone growth, and also play a role in pattern formation of the dentition and the skeleton in the early embryonic phase.
Their role in regeneration of bone and periodontium is studied using cell- and animal experiments.
