introduction: dental pulp has neural fibers that produce neuropeptides like substance p (sp) and calcitonin gene-related peptide (cgrp). the inflammation of dental pulp can lead to an increase amount of sp and cgrp release, especially in symptomatic irreversible pulpitis. therefore, it can be assumed that neuropeptides have some role in the progression of inflammation of the dental pulp. the ai...

Estimation of the time since death is important in forensic medicine, and so far not much is known in employing dental pulp for such purposes. The tooth organ is the hardest organ in the human body, with a loose connective tissue of dental pulp situated within a rigid encasement of mineralized surrounding tissues. Human material was obtained from 31 corpses of people who died in car and train a...

Pathogen recognition receptors (PRRs) are a class of germ line-encoded receptors that recognize pathogen-associated molecular patterns (PAMPs). The activation of PRRs is crucial for the initiation of innate immunity, which plays a key role in first-line defense until more specific adaptive immunity is developed. PRRs differ in the signaling cascades and host responses activated by their engagem...

BACKGROUND Stem cells from Human Exfoliated Deciduous teeth (SHED) have the capability to differentiate into neural cells. Neurotrophins including Nerve Growth Factor (NGF), Brain-Derived Neurotrophic Factor (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4) have neurogenesis, neurotrophic, or neuroprotective effects and are expressed in developing teeth. The aim of this study was to meas...

The recent advances in molecular biology have revolutionized all aspects of dentistry. DNA, the language of life yields information beyond our imagination, both in health or disease. DNA fingerprinting is a tool used to unravel all the mysteries associated with the oral cavity and its manifestations during diseased conditions. It is being increasingly used in analyzing various scenarios related...

Functional tissue engineering for bone augmentation requires the appropriate combination of biomaterials, mesenchymal stem cells, and specific differentiation factors. Therefore, we investigated the morphology, attachment, viability, and proliferation of human dental pulp stem cells cultured in xeno-free conditions in human serum medium seeded on β-tricalcium phosphate/poly(l-lactic acid/caprol...

L-type voltage-dependent CaV1.2 channels play an important role in the maintenance of intracellular calcium homeostasis, and influence multiple cellular processes. C-terminal cleavage of CaV1.2 channels was reported in several types of excitable cells, but its expression and possible roles in non-excitable cells is still not clear. The aim of this study was to determine whether distal C-termina...

Dental pulp tissue contains dental pulp stem cells (DPSCs). Dental pulp cells (also known as dental pulp-derived mesenchymal stem cells) are capable of differentiating into multilineage cells including neuron-like cells. The aim of this study was to examine the capability of DPSCs to differentiate into neuron-like cells without using any reagents or growth factors. DPSCs were isolated from teet...

Aging is identified by a progressive decline of physiological integrity leading to age-related degenerative diseases, but its causes is unclear. Human dental pulp stem cells (hDPSCs) has a remarkable rejuvenated capacity that relies on its resident stem cells. However, because of the lack of proper senescence models, exploration of the underlying molecular mechanisms has been hindered. Here, we...
