An Insight Into Neurophysiology of Pulpal Pain: Facts and …
WEBOct 2, 2013 · Sensory nerve fibers of the dental pulp are afferent endings of the trigeminal cranial nerve. These fibers reach the root canal through the apical foramen, going to the root pulp in lumps. These lumps are often associated with blood vessels in a collagen sheath, forming the neurovascular bundle.
Dental pulp neurophysiology: part 1. Clinical and diagnostic ...
WEBThe nerve supply of the dentin-pulp complex is mainly made up of A fibres (both delta and beta) and C fibres. They are classified according to their diameter and their conduction velocity. The A fibres are mainly stimulated by an application of cold, producing sharp pain, whereas stimulation of the C fibres produces a dull aching pain.
Pulp (tooth) - Wikipedia
WEBSensory nerve fibers that originate from inferior and superior alveolar nerves innervate the odontoblastic layer of the pulp cavity. These nerves enter the tooth through the apical foramen as myelinated nerve bundles.
The Role of Sensory Nerves in Dental Pulp Homeostasis: …
WEBJan 17, 2024 · Sensory nerves constitute a crucial component of the dental pulp. However, the precise involvement of sensory nerves in pulp homeostasis remains uncertain. In this study, we observed the short-term and long-term histological changes in the dental pulp after inferior alveolar nerve transection.
Dental nerves: a neglected mediator of pulpitis - Zhan - 2021 ...
WEBSep 2, 2020 · Several studies have shown that at least two different branches of the peripheral nervous system are stimulated during pulpal inflammation: the sensory nerve fibres, which act mainly in a pro-inflammatory manner, and the sympathetic nerve fibres, which may have anti-inflammatory effects.
Role of intradental A- and C-type nerve fibres in dental pain ...
WEBSingle fibre recordings of intradental nerve activity in experimental animals have shown that in addition to A-fibres a considerable number of C-type primary afferents innervate the dental pulp. This is in accordance with the results of neuroanatomical studies, which indicate that 70-80% of pulpal axons in human, monkey, dog, and cat teeth are ...

WEBJul 26, 2019 · Henry, M. A., Luo, S. & Levinson, S. R. Unmyelinated nerve fibers in the human dental pulp express markers for myelinated fibers and show sodium channel accumulations.
Inflammatory Response Mechanisms of the Dentine–Pulp …
WEBFeb 2, 2021 · In dental pulp, nerve fibers are a source of nNOS, and endothelial cells produce eNOS; both have been identified in odontoblasts [80,81]. In resting cells, iNOS is not expressed, but it is expressed in cells during physiological activity [82,83] and during pre- and postnatal development [84,85].
Unmyelinated nerve fibers in the human dental pulp express …
WEBMar 19, 2012 · The human dental pulp is richly innervated by unmyelinated nerve fibers and historically much of the pain associated with toothache was thought to result from activation of small diameter neurons that typically give rise to c-fibers.
Dental neuroplasticity, neuro-pulpal interactions, and nerve ...
WEBApr 1, 2003 · This review covers current information about the ability of dental nerves to regenerate and the role of tooth pulp in recruitment of regenerating nerve fibers. In addition, the participation of dental nerves in pulpal injury responses and healing is discussed, especially concerning pulp regeneration ….
