Neuropeptides in dental pulp: the silent protagonists

Area of Science:

• Neuroscience
• Dentistry
• Immunology

Background:

• Dental pulp is richly innervated by sensory, sympathetic, and parasympathetic fibers.
• Neuropeptides are key mediators of pulpal blood flow, neurogenic inflammation, and pain signaling.
• Understanding these neuronal systems is crucial for managing pulpal pathology.

Purpose of the Study:

• To review recent advances in dental pulp neuropeptide research.
• To discuss neuropeptide roles in pulp physiology, injury response, and inflammation.
• To explore therapeutic strategies targeting neuropeptide pathways for dental pain and pathology.

Main Methods:

• Literature review of studies on neuropeptide expression, release, and function in dental pulp.
• Analysis of research on neuropeptide receptor interactions with pulp and immune cells.
• Examination of studies on neuropeptides in pain mechanisms and periapical lesion development.

Main Results:

• Neuropeptides significantly influence pulpal blood flow and neurogenic inflammation.
• Neuropeptide release is triggered by dental procedures and injuries, showing plasticity.
• Receptor interactions mediate inflammatory responses and contribute to pulp necrosis and periapical lesion expansion.

Conclusions:

• Neuropeptides are critical in dental pulp physiology, pathology, and pain.
• Targeting neuropeptide receptors offers promising therapeutic avenues for dental pain and inflammation.
• Future therapies may involve modulating neuropeptide expression or blocking receptors for clinical benefit.
