BACKGROUND Low-intensity ultrasound is considered an effective non-invasive therapy to stimulate hard tissue repair, in particular to accelerate delayed non-union bone fracture healing. More recently, ultrasound has been proposed as a therapeutic tool to repair and regenerate dental tissues. Our recent work suggested that low-frequency kilohertz-range ultrasound is able to interact with dental ...

dental pulp stem cells (dpscs) can be found within the cell rich zone of dental pulp. these stem cells, under specific stimuli, differentiate into many cell types which have wide therapeutic applications.   the dental stem cells are derived from both deciduous and permanent teeth. the viable dental stem cells are very simple to collect, without any mortality and morbidity. dental pulp stem cell...

introduction: this study was designed to evaluate the prevalence of referred pain with pulpal source in the head, face and neck region among patients referred to dental school of shahid beheshti university mc, tehran, iran in 2004. materials and methods: in this cross-sectional study, 100 patients (55 males and 45 females) referred to oral medicine department of shahid beheshti dental school ev...

The development of biomaterials capable of driving dental pulp stem cell differentiation into odontoblast-like cells able to secrete reparative dentin is the goal of current conservative dentistry. In the present investigation, a biomembrane (BM) composed of a chitosan/collagen matrix embedded with calcium-aluminate microparticles was tested. The BM was produced by mixing collagen gel with a ch...

Dental pulp represents a promising and easily accessible source of mesenchymal stem cells for clinical applications. Many studies have investigated the use of human dental pulp stem cells and stem cells isolated from the dental pulp of human exfoliated deciduous teeth for bone tissue engineering in vivo. However, the type of scaffold used to support the proliferation and differentiation of dent...

We characterized a voltage-dependent ionic current in dental pulp cells on dental pulp slices using a nystatin perforated-patch recording configuration. The outward currents in dental pulp cells were inhibited by the following channel blockers: 1) Ca(2+)-free extracellular solution containing 10 mM Ba2+, 2) extracellular 400 nM apamin and 3) extracellular 300 nM 4,4'-diisothiocyanatostilbene-2,...

There are several studies about the cytotoxic effects of dental materials in contact with the pulp tissue, such as calcium hydroxide (CH), adhesive systems, resin composite and glass ionomer cements. The aim of this review article was to summarize and discuss the cytotoxicity and biocompatibility of materials used for protection of the dentin-pulp complex, some components of resin composites an...

Enzymatic and immunological properties of alkaline phosphatase [ALP; orthophosphoric monoester phosphohydrolase, alkaline optimum, EC 3.1.3.1.] in the human dental pulp were investigated. In inhibition and thermal inactivation studies, dental pulp ALP showed properties of universal-type ALP (kidney/bone/liver type). Dental pulp ALP cross-reacted with polyclonal and monoclonal antibodies against...

To investigate the effects of open dentinal tubules on the morphological and functional characteristics of dental pulp cells. Morphological changes in human dental pulp cells that were seeded onto dentin discs with open dentinal tubules were investigated on days 1, 2, 4, and 10 of culture using scanning electron microscopy and fluorescence microscopy. Samples collected on days 1, 3, 6, 8, and 1...
