Structure and organization of odontoblasts
The Anatomical Record, 1996Differentiation of odontoblasts involves cell-to-cell recognition, contact stabilization involving the formation of attachment specializations, cytoplasmic polarization, development of the protein synthetic and secretory apparatus, and the active transport of mineral ions.

Expression of amelogenin in odontoblasts
Bone, 2003Amelogenin is the major enamel protein produced by ameloblasts. Its expression has been shown to be down-regulated in ameloblasts of vitamin-D-deficient (-D) rats. The potential expression and localization of amelogenin in odontoblasts and its regulation by vitamin D were investigated in this study.

Odontoblasts are dentin-secreting cells that survive for the whole life of a healthy tooth. Once teeth are completely erupted, odontoblasts transform into a mature stage that allows for their functional conservation for decades, while maintaining the capacity for secondary and reactionary dentin secretion.

Nucleoli of human odontoblasts
Archives of Oral Biology, 1972Abstract Nucleoli of human odontoblasts were studied in smears stained with buffered toluidine blue at pH 5, for the demonstration of RNP-containing structures, including nucleoli. The odontoblasts were obtained from 5 premolars removed for orthodontic reasons.

Terminal end of the odontoblast process
Journal of Endodontics, 1988The terminal end of the odontoblast process wasexamined in rat and human molars by scanning electron microscopy on teeth that were surface demineralized and collagenase digested. It was found that in both samples the odontoblast process ended as a dilated sphere at or just below the dentinoenamel junction.

Activation of mitophagy in inflamed odontoblasts
Oral Diseases, 2019AbstractObjectivesMitophagy is an important mitochondrial quality control mechanism. In this study, we investigated the mitochondrial damage and mitophagy occurred in inflammatory human dental pulp and lipopolysaccharide‐stimulated preodontoblasts.Materials and MethodsIn dental pulp tissues and lipopolysaccharide‐stimulated preodontoblasts ...

Another look at the odontoblast process
Journal of Endodontics, 1984Freshly extracted human third molars and bicuspids with incompletely developed roots were cryofractured in liquid nitrogen and placed in Karnovsky's fixative. The specimens were decalcified in formic and hydrochloric acids followed by digestion in collegenase.

Multifocal Odontoblastic Dysplasia in a Dog
Journal of Veterinary Dentistry, 2010A two-year-old Boerboel dog presented for a discolored left maxillary canine tooth. Dental radiographs revealed abnormally mineralized pulp within the discolored tooth. Similar radiographic findings were also seen in both maxillary third incisor teeth and in the remaining canine teeth to varying degrees.

The ultrastructure of human fetal odontoblasts
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1970The ultrastructure of odontoblasts of deciduous teeth from two human fetuses (CRL 159 and 195 mm) was investigated. The human odontoblast is a polarized cell with a characteristic localization of its organelles and demonstrates similarities with odontoblasts from non-human materials.

The fine structure of the mouse odontoblast
Archives of Oral Biology, 1968Abstract A study of the fine structure of the odontoblasts of young mice was undertaken in order to further elucidate the secretory role of this cell in the production of dentine. The observations suggested that fully differentiated odontoblasts possess all of the cytoplasmic characteristics of cells engaged in the production of proteins for external
