Teeth have been recognized as providing a useful long-term record of lead (Pb2+) uptake. However, information regarding the effects of lead on dental pulp tissue cells that foster dentinogenesis is scarce. This study investigated the effects of lead on dental pulp tissue using human dental pulp fibroblasts in vitro. Dental pulp cells from the teeth of young patients (aged 17-24 years) were cult...

Adequate vascularization, a restricting factor for the survival of engineered tissues, is often promoted by the addition of stem cells or the appropriate angiogenic growth factors. In this study, human dental pulp stem cells (DPSCs) and stem cells from the apical papilla (SCAPs) were applied in an in vivo model of dental pulp regeneration in order to compare their regenerative potential and con...

Pulpal disease, specifically dental pulpitis, is triggered by exogeneous stimuli from cariogenic bacteria or traumatic injury. The specific host defense in the dental pulp is regulated by the innate and adaptive immunity, of which the pulp-dentin complex odontoblasts play an essential role in the early stage of the dental immune response. It has been reported that the NLRP3 inflammasome is expr...

BACKGROUND Dental pulp stem cells (DPSCs) play an important role in tissue regeneration. This study compares the growth kinetics and characterization of third molar and first premolar human DPSCs. MATERIAL AND METHODS Dental pulp tissues were isolated from human first premolar and third molar teeth and were digested by treating them with collagenase type I. Single-cell suspensions from each d...

Background Recently, the clinical use of low power lasers has increased, and it is said that wound healing is accelerated by their irradiation. The aim of this study was evaluation of the effect of platelet-rich plasma on proliferation and differentiation of human dental pulp stem cells with or without Ga-Al-As laser. Methods: In this experimental study, human lower third molar dental pulp c...

Background Currently, the use of stem cells from permanent (DPSCs) and deciduous teeth (SHEDs) has enabled many therapeutic advances. Despite numerous sources of stem cells, DPSCs and SHEDs have shown several advantages, since the isolation method is noninvasive and cells present rapid expansion in vitro [1]. DPSCs have shown the capacity to form a dentin-pulp like complex. Due to its high oste...

The objective of this study was to determine the effects of Prevotella intermedia, Fusobacterium nucleatum and Lactobacillus casei on the production of IL-8 by human dental pulp cells. Human dental pulp cells from teeth of young patients (aged 18-25 years) were cultured and tested with sonicated P. intermedia ATCC 25611, F. nucleatum ATCC 25586 and L. casei ATCC 4646 extracts. IL-8 secreted int...

Dental pulp has been identified as a novel and promising stem cell source. The following systematic review presents and summarises in vivo studies that have used stem cells from the dental pulp of permanent and deciduous teeth to repair or regenerate non-dental tissues. An electronic customised search was performed using 4 different databases (Entrez PubMed, Cab Abstracts, Scopus and Web of Sci...
