Romundina and the evolutionary origin of teeth [PDF]

, 2015
Theories on the origin of vertebrate teeth have long focused on chondrichthyans as reflecting a primitive condition—but this is better informed by the extinct placoderms, which constitute a sister clade or grade to the living gnathostomes.

Establishment of an MRI‐Based Diagnostic Approach to Identify Critical Pulpal Inflammation Zones in a Rat Caries‐Derived Pulpitis Model

International Endodontic Journal, EarlyView.
ABSTRACT Aim To establish a magnetic resonance imaging (MRI)‐based diagnostic approach for identifying ‘critical pulpal inflammation’ zones in a rat model of caries‐derived pulpitis. Methodology Caries‐derived pulpitis was induced in the molars of Sprague–Dawley rats using the caries‐derived pulpitis model.

Expression of nerve growth factor (NGF), TrkA and p75NTR in developing human foetal teeth

Frontiers in Physiology, 2016
Nerve growth factor (NGF) is important for the development and the differentiation of neuronal and non-neuronal cells. NGF binds to specific low- and high-affinity cell surface receptors, respectively p75NTR and TrkA. In the present study, we examined by

Long-Term Fluoride Release from Dental Resins Affects STRO-1+ Cell Behavior. [PDF]

, 2015
Fluoride-releasing restorative dental materials can be beneficial to remineralize dentin and help prevent secondary caries. However, the effects of fluoride release from dental materials on the activity of dental pulp stem cells are not known.

Dentine Regeneration With Calcium Strontium Silicate: In Vitro Odontogenic Differentiation, Antimicrobial Activity, Immunomodulation and In Vivo Pulpotomy in Rat Molars

International Endodontic Journal, EarlyView.
ABSTRACT Aim This study examined the in vitro and in vivo performance of calcium strontium silicate (CSR) as a novel biomaterial for vital pulp therapy (VPT), assessing its odontogenic differentiation, antibacterial activity, immunomodulation, inflammatory response and dentine regeneration potential compared to calcium silicate (CS) and Mineral ...

Mouse-induced pluripotent stem cells differentiate into odontoblast-like cells with induction of altered adhesive and migratory phenotype of integrin.

PLoS ONE, 2013
Methods for differentiating induced pluripotent stem (iPS) cells into odontoblasts generally require epithelial-mesenchymal interactions. Here, we sought to characterize the cells produced by a 'hanging drop' technique for differentiating mouse iPS cells

Human odontoblast-like cells produce nitric oxide with antibacterial activity upon TLR2 activation

Frontiers in Physiology, 2015
The penetration of cariogenic oral bacteria into enamel and dentin during the caries process triggers an immune/inflammatory response in the underlying pulp tissue, the reduction of which is considered a prerequisite to dentinogenesis-based pulp ...

Defining properties of neural crest-derived progenitor cells from the apex of human developing tooth [PDF]

, 2008
The connective tissue of the human tooth arises from cells that are derived from the cranial neural crest and, thus, are termed as "ectomesenchymal cells." Here, cells being located in a pad-like tissue adjacent to the apex of the developing tooth, which

Inflammation‐Regeneration Axis of Dental Pulp Stem Cells: Wnt/NF‐κB Crosstalk

International Endodontic Journal, EarlyView.
ABSTRACT Background Inflammation critically determines dental pulp regenerative outcomes, with dental pulp stem cells (DPSCs) orchestrating tissue homeostasis through differentiation, self‐renewal and immunomodulation processes dynamically regulated by Wnt/β‐catenin and NF‐κB signaling crosstalk.

Isolation and in vitro Characterization of Mesenchymal Stem Cells Derived from the Pulp Tissue of Human Third Molar Tooth [PDF]

Iranian Journal of Medical Sciences, 2010
Background: It is still controversial that the stem cells isolatedfrom human dental pulp meets the criteria for mesenchymalstem cells (MSCs). The aim of the present study wasto examine whether or not they are MSCs, or are distinct stemcells population ...
