Significats de cementum en anglès

The formation and attachment of new cementum is crucial for periodontium regeneration.

Our results indicate that cell autonomous cementum defects are causing early tooth loss in CLS patients.

Additionally, the structural inhomogeneity observed within ultrasectioned cementum contributed to a broader range of mechanical properties.

All specimens showed various degrees of subsurface dissolution of mineral and bacterial invasion of the cementum.

Newly formed cementum was observed with both treatments.

The current studies employed cementoblasts to determine the role(s) and mechanisms of PTHrP in regulating cementum formation.

Nevertheless, the CM graft attained more tissue regeneration, characterized by a shorter epithelium and a larger new cementum formation.

Under the enamel and cementum of each tooth is the dentin, which is yellow, porous, and harder than bone.

Root decay also spreads quickly, since the cementum covering on the root is not as hard and as thick as enamel.

Electron microscopically, MP was found in the pericellular spaces of cementum and bone lacunae, particularly on collagen fibrils and amorphous material.

It is not known if the cementocyte is a dynamic actor in cementum metabolism, comparable to the osteocyte in the bone.

In this study it was hypothesized that the structure of cementum is inhomogeneous, contributing to a significant variation in mechanical properties of cementum.

Newly apposited cementum and alveolar bone layers were approximately 3-fold thicker in the experimental vs the control group, whereas periodontal ligament width was maintained.

Alveolar bone defects, which are characterized by a relatively narrow space and location adjacent to the cementum, require promising substitute biomaterials for their regeneration.

Labeled tissue sections revealed significant amounts of new bone and cementum apposition at the root apex of the unopposed side following supereruption for 12 days.

Results: The cKO mice underwent a remarkable loss of alveolar bone and cementum, along with inflammation of the periodontal ligament and formation of periodontal pockets.
