Conditional Knockout of Raptor/mTORC1 Results in Dentin Malformation

Frontiers in Physiology, 2019
mTORC1 signaling plays an important role in extracellular and intracellular signals, including growth factors, nutrients, energy metabolism, and stress. However, the functional role of mTORC1 in dentinogenesis is unknown.

The Critical Role of MMP13 in Regulating Tooth Development and Reactionary Dentinogenesis Repair Through the Wnt Signaling Pathway

Frontiers in Cell and Developmental Biology, 2022
Matrix-metalloproteinase-13 (MMP13) is important for bone formation and remodeling; however, its role in tooth development remains unknown. To investigate this, MMP13-knockout (Mmp13−/−) mice were used to analyze phenotypic changes in the dentin–pulp ...

Optimized micro‐sized cell sphere‐matrix niche co‐aggregates promote efficient oral and craniomaxillofacial bone regeneration

BMEMat, EarlyView.
The construct of cell‐niche co‐aggregates (GelMA‐SHED sphere‐DDMPs) promotes cranial and periodontal bone regeneration and ensures angiogenic‐osteogenic coupling by downregulating miR‐34c‐5p to enhance the expression of NOTCH1 and its intracellular domain (NICD).

Autoradiographic analysis of odontoblast replacement following pulp exposure in primate teeth [PDF]

, 1990
Cell migration and replication associated with odontoblast replacement occurring soon after pulp exposure in primate teeth were studied. Class 5 cavity preparations resulting in pulp exposures were restored with a calcium hydroxide-containing capping ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors

Developmental Dynamics, EarlyView.
Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

Polarity of Mature Human Odontoblasts

Journal of Dental Research, 2013
Odontoblast polarization is based on histological appearance as columnar cells with asymmetric disposition of organelles and plasma membrane domains. However, little is known about the odontoblast plasma membrane organization. We investigated odontoblast membrane polarity using influenza virus hemagglutinin and vesicular stomatitis virus glycoprotein ...

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Different from bone: Tooth formation and enameloid mineralization are not affected by reduced dietary phosphorus intake

Developmental Dynamics, EarlyView.
Abstract Background Vertebrates rely on phosphorus intake for skeletal mineralization. In humans, hypomineralized teeth associated with rickets, hypophosphatemia, hypophosphatasia, or idiopathic molar‐incisor‐hypomineralization pose significant problems.

The Extent of the Odontoblast Process in Human Dentin

, 1979
Impacted human third molar teeth were examined, both with the light and electron microscope, to determine the extent of the odontoblast process. The odontoblast process was found to be limited to the inner third of coronal dentin and inner half of mid ...
