Cell attachment activity of cementum: bone sialoprotein _ identified in cementum
Journal of Periodontal Research, 1991Considerable 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 ...

The developmental biology of cementum
The International Journal of Developmental Biology, 2001In conclusion, we have reviewed an extensive literature on early cementogenesis and performed a detailed morphological and molecular analysis to illustrate and verify key issues in the current debate about epithelial and mesenchymal contributions to root cementum.

In vitro sorption of IgG to cementum
Journal of Periodontal Research, 1984The nature of the interaction between root surfaces and gingival fluid proteins has not been studied. Therefore, a series of in vitro investigations were undertaken to develop an assay to determine sorption of prominent gingival fluid proteins to the cementum.In initial studies extracted teeth were immersed in various concentrations of whole human ...

Cementum thickness and mesial drift
Journal of Clinical Pharmacy and Therapeutics, 1990Abstract 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.

C EMENTUM may be defined as a bony covering of the roots of the teeth. It consists of a matrix composed of calcified collagenous fibrils and may be either cell-free or contain cement corpuscles, sometimes called cementocptes. The first formed layer is acellular or hyaline cementum.

Soluble glycosylated phosphoproteins of cementum
Calcified Tissue International, 1989Ethylenediaminetetraacetate 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)

Bacteria invading periapical cementum
Journal of Endodontics, 1994The 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

Distribution of fluoride in human cementum
Archives of Oral Biology, 1985Fluoride and phosphorus concentrations were determined in layers of cementum and dentine serially-abraded from the root surface, passing through the cementum-dentine junction and into the underlying dentine, using silicon carbide-impregnated film. The concentrations of F in the cementum mineral were variable but consistently maximal at or near to the ...

Cementum and Periodontal Ligament Regeneration
2015The unique anatomy and composition of the periodontium make periodontal tissue healing and regeneration a complex process. Periodontal regeneration aims to recapitulate the crucial stages of wound healing associated with periodontal development in order to restore lost tissues to their original form and function and for regeneration to occur, healing ...

Defining the Roots of Cementum Formation
Cells Tissues Organs, 2005Significant progress has been seen in research aimed at regeneration of the disease-damaged periodontium. Our own strategy has been to approach periodontal tissue development (i.e. root, cementum, periodontal ligament, and bone) as a source for the identification of key regulators of cellular processes that may be applicable to periodontal tissue ...
