AbstractObjectives: The aim of this study was to analyze the association between Hertwig's epithelial root sheath (HERS) cells, enamel matrix proteins (EMPs), and cementogenesis.Material and Methods: Porcine teeth were examined at the beginning of root formation by light and transmission electron microscopy.

Intermittent parathyroid hormone promotes cementogenesis via ephrinB2‐EPHB4 forward signaling
Journal of Cellular Physiology, 2020AbstractIntermittent parathyroid hormone (PTH) promotes periodontal repair, but the underlying mechanisms remained unclear. Recent studies found that ephrinB2‐EPHB4 forward signaling mediated the anabolic effect of PTH in bone homeostasis. Considering the similarities between cementum and bone, we aimed to examine the therapeutic effect of PTH on ...

Intermittent parathyroid hormone promotes cementogenesis in a PKA‐ and ERK1/2‐dependent manner
Journal of Periodontology, 2019AbstractBackgroundIntermittent parathyroid hormone (PTH) promotes cementogenesis and provides a promising biotherapeutic to rehabilitate resorbed roots. However, the underlying mechanisms remain inconclusive. Cyclic aenosine monophosphate (AMP)‐dependent protein kinases A (PKA) and extracellular signal‐regulated MAP kinases 1/2 (ERK1/2) are key ...

AbstractDestruction of the periodontium is normally associated with periodontal disease, although many other factors, such as trauma, aging, infections, orthodontic tooth movement and systemic and genetic diseases, can contribute to this process. Strategies (such as guided tissue regeneration) have been developed to guide and control regeneration using

Deciduous central incisor tooth development and coronal cementogenesis in cattle
Archives of Oral Biology, 1969Abstract This study documents chronologically, growth and development of the bovine deciduous central incisor tooth from the earliest available stages of odontogenesis to exfoliation. Gross morphologic and histologic studies were carried out on 48 bovine mandibles.

A light and electron microscopic study of coronal cementogenesis
Archives of Oral Biology, 1968Abstract The microscopic examination of bovine mandibular second molars in various stages of development has indicated that coronal cementogenesis is preceded by degeneration of the reduced enamel epithelum. The tendency for odontogenic epithelium to degenerate appears to be strong, and in certain areas ameloblasts may begin to atrophy prior to ...

Expression of attachment proteins during cementogenesis.
Journal de biologie buccale, 1991There is general agreement that during development the extracellular environment plays a critical role in controlling cell differentiation. Data generated from numerous studies support the possibility that cell attachment proteins and their corresponding cell receptors are possible candidates for this role.

Towards a Cellular and Molecular Understanding of Periodontics: Cementogenesis Revisited
Journal of Periodontology, 1976C U R R E N T C O N C E P T S of plaque-associated inflammatory periodontal disease have been derived to a large extent from histopathologic and electron microscopic descrip tions of the lesions. The most common form of plaqueassociated inflammatory periodontal disease appears during childhood or young adulthood and is associated with the presence of ...

Cementogenesis examined from the viewpoint of microcirculation.
The International journal of periodontics & restorative dentistry, 2009The purpose of this study was to perform a three-dimensional observation, via microvascular corrosion casts, of the microcirculation system during deposition of cementum after flap surgery and to investigate the permeable structure of the vascular endothelium.

Age-related changes of the cementogenesis in the senescence-accelerated mouse (SAM)
Journal of Periodontal Research, 1996Cementogenesis of the molars with aging was studied using senescence accelerated mouse (SAM) which included SAMP2/Iw and SAMP8//Iw as prone strains, and SAMRl/Iw as a resistant strain. Morphometric analysis was done for the cementum thickness at 2, 6, 12 and 16 months of age on 4 parts of the mice, i.e. at the mesial (M), the distal (D), the apical (A)
