Cementum Proteins Beyond Cementum

2021
Dental cementum is a specialized complex structural component of teeth, covering its roots. It is avascular, non-innervated, does not remodel but some of it can grow continuously through life (Bosshardt and Selvig. Dental cementum: the dynamic tissue covering of the root. Periodontol 2000 13:41–75, 1997). Comprehensive knowledge of this tissue has been

Origins of cementum

Oral Diseases, 1996
There are diverging opinions about the role of Hertwig's epithelial root sheath in the formation of cementum. In the present review this role is discussed. There is increasing evidence that Hertwig's epithelial root sheath is actively involved in the formation of both acellular and cellular cementum.

Bacteria invading periapical cementum

Journal of Endodontics, 1994
The aim of this study was to determine whether microorganisms invade periapical cementum of human teeth from the adjacent periapical lesions. We therefore attempted to isolate microorganisms from periapical cementum through the adoption of standard anaerobic procedures for obligate anaerobes. Samples of cementum were taken from 10 amputated tooth roots

Glycosaminoglycans of human cementum

Journal of Periodontal Research, 1988
The glycosaminoglycans in human cementum have been studied. Following proteolytic digestion of guanidine/EDTA and collagenase extracts of cementum, glycosaminoglycans were isolated and then separated by cellulose acetate membrane electrophoresis. After specific elimination by enzymatic and chemical treatments the glycosaminoglycans were identified as ...

Cementum and Dentin in Hypophosphatasia

Journal of Dental Research, 2005
Hypophosphatasia (HPP) often leads to premature loss of deciduous teeth, due to disturbed cementum formation. We addressed the question to what extent cementum and dentin are similarly affected. To this end, we compared teeth from children with HPP with those from matched controls and analyzed them microscopically and chemically.

Cell attachment activity of cementum: bone sialoprotein _ identified in cementum

Journal of Periodontal Research, 1991
Considerable research effort has been directed at preparing root surfaces in a fashion that would promote cell attachment leading to periodontal regeneration; however, no methods have proven to be clinically predictable. Identification of attachment protein(s) associated with the root surface matrix of cementum may prove valuable for developing ...

Soluble glycosylated phosphoproteins of cementum

Calcified Tissue International, 1989
Ethylenediaminetetraacetate and hydrochloric acid (EDTA) (HCl) extracts of cementum were fractionated by molecular sieving, ion exchange chromotography, and reverse phase high precision liquid chromatography (HPLC). Nine fractions were isolated, all of which contained serine phosphate, threonine phosphate, and high concentrations of aspartic acid (asp)

Cementum thickness and mesial drift

Journal of Clinical Pharmacy and Therapeutics, 1990
Abstract Cementum thickness increases uniformly with age, and questionably from functional stimulation due to tensional forces. Mesial drift of teeth results in tensional forces on distal root surfaces. This study evaluated whether there was any discernible effect on cementum thickness related to mesial drift in humans.

Cementum: A Phosphate-sensitive Tissue

Journal of Dental Research, 2002
Ectopic calcification within joints has been reported in humans and rodents exhibiting mutations in genes that regulate the level of extracellular pyrophosphate, e.g., ank and PC-1; however, periodontal effects of these mutations have not previously been examined.
