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.

Defining the Roots of Cementum Formation

Cells Tissues Organs, 2005
Significant 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 ...

Piezoelectricity in cementum, dentine and bone

Archives of Oral Biology, 1989
Unlike the dental hard tissues, bone remodels when subjected to orthodontic forces. Bone is also piezoelectric (generates a surface electrical charge upon application of force). In dentine and cementum from sperm whale teeth (which gave samples of sufficient size), the existence and magnitude of piezoelectricity were examined and compared with human ...

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

In vitro sorption of IgG to cementum

Journal of Periodontal Research, 1984
The 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: 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.

The incorporation of epithelial cells by cementum

Journal of Ultrastructure Research, 1969
The formation of cellular cementum was studied by electron microscopy at the advancing edge of developing roots of molars of 25-day-old rats. It was found that the basement lamina about Hertwig's epithelial root sheath first becomes discontinuous on the dental sac side, collagen and cementoblast processes appearing within the formerly intact epithelial

Effects of cementum–dentine junction and cementum on the mechanical response of tooth supporting structure

Journal of Dentistry, 2010
The aim of the present work is to investigate the effects of cementum-dentine junction (CDJ) and cementum on the stress distribution in the periodontal ligament (PDL) and alveolar bone.Based on the anatomical profiles and the recently reported theories about the tooth attachment mechanism, the finite element (FE) model of a mandibular second premolar ...

Acemannan sponges stimulate alveolar bone, cementum and periodontal ligament regeneration in a canine class II furcation defect model.

Journal of Periodontal Research, 2014
BACKGROUND AND OBJECTIVE Periodontal disease is a common infectious disease, found worldwide, causing the destruction of the periodontium. The periodontium is a complex structure composed of both soft and hard tissues, thus an agent applied to regenerate
