Membrane junctions on cat odontoblasts
Archives of Oral Biology, 1975Abstract The odontoblast layer of the pulp was examined after perfusion fixation with buffered aldehydes. Desmosomal junctions occur between only some of the odontoblasts at the predentinal border. Pale cytoplasmic processes similar in morphology to nerve terminals in the intercellular spaces make specialized junctions on the cell bodies of the ...

Odontoblasts: Vacuoles and Inclusions
Science, 1961Lipid granules have been found in the cytoplasm of odontoblasts and in the odontoblastic extensions within the dentinal tubules. It is suggested that these granules represent specific activity on the part of the normal cell as well as an increase in number after injury.

A histochemical study of the human odontoblast
Archives of Oral Biology, 1967Abstract Unfixed, undemineralized cold microtome sections of human teeth were used to study the histochemical characteristics of the odontoblast. As these cells differentiated from the mesenchyme of the papilla they acquired an increased content of ribonucleic acid, showed a marked carbohydrate content and developed activity of the hydrolytic enzymes

Inflammation in the odontoblastic layer of the dental pulp
The Journal of the American Dental Association, 1959When the dentin is exposed by operative procedures, the odontoblasts invariably are injured and undergo subtle changes which initiate inflammation. The inflammatory process is described, as are the processes of repair or necrosis.

Cell Division and Cytodifferentiation of Odontoblasts
Differentiation, 1976The chronological delay of overt cytodifferentiation of odontoblasts in isochronal and heterochronal associations between inner dental epithelium and preameloblasts was analysed. The in vitro action of FUdR of tooth germs was summarised. The respective role of cell interaction and specific cell cycle was discussed.

The fine tuning role of microRNA-RNA interaction in odontoblast differentiation and disease.
Oral Diseases, 2015Dentinogenesis imperfecta and dentin dysplasia are two common types of genetic oral diseases resulted from the aberrant differentiation of odontoblast.

Establishment of odontoblastic cells, which indicate odontoblast features both in vivo and in vitro
Journal of Oral Pathology & Medicine, 2013Tooth tissue engineering offers very attractive perspectives for elaboration of regenerative treatments, which enables to cure tooth loss and restore quality of life of the patients. To elaborate such treatment, isolation and culture of dental pulp cell must be achieved as a key element.

Cathepsind activity in isolated odontoblasts
Calcified Tissue Research, 1977The presence of an acid proteinase with a high activity has been demonstrated in isolated odontoblast-predentine material from dentinogenically active rat incisors. The enzyme was identified as cathepsin D (EC 3.4.23.5). The possible significance of the enzymatic degradation of proteoglycans and glycosaminoglycans in the course of the calcification ...

Mechanosensitive Ion Channels in Odontoblasts [PDF]
, 2007 Odontoblasts are post-mitotic cells involved in the dentine formation throughout the life of the tooth and suspected to play a role in tooth pain transmission. They are organized as a single layer of specialized cells along the interface between dental pulp and calcified dentinal tubules into which run a cellular extension (odontoblast process) bathed ...

Role of the odontoblast process
1990The odontoblast is a member of a family of secretory connective tissue cells. Unlike other members of the family, its cell body does not become embedded in the tissue it forms but retreats as new material is deposited, leaving a single narrow extension from which the components of the forming tissue are released.
