Dental nerves play pivotal role in mediating pulpal inflammatory responses: Study

Thus, understanding how dental nerves participate in pulpitis could have important clinical ramifications for endodontic treatment. As one of the most densely innervated tissues, the dental pulp contains abundant nerve fibres, including sensory, sympathetic and parasympathetic nerve fibres.

The major function of dental nerves is thought to be the transmission of afferent signals to the central nervous system (CNS), which ultimately triggers various responses. More specifically, the pathway for signal transmission in the dental pulp starts with the detection of stimuli by primary afferent fibres. The first-order neurons in trigeminal ganglion project central terminals to the neurons that are located within the brainstem; these signals are then sent to the thalamus, and the somatosensory cortex finally receives the thalamic inputs. Almost all stimuli applied to the dental pulp result in the sensation of pain, which as one of the most commonly reported symptoms, can vary in intensity.
