Abstract:
BACKGROUND:With the development of researches on periodontal disease etiology and neuroendocrine factors, the role of neuroendocrine factors on the pathogenesis of periodontal disease and tissue restoration has become a hot spot.
OBJECTIVE:To summarize the biological effect of neuropeptides on periodontal tissues and the changes of periodontal tissue after nerve injury.
METHODS:A computer-based search of articles was performed in CNKI, Wanfang and PubMed databases using the key words ofneuropeptides, calcitonin gene related peptide, substance P, vasoactive intestinal peptide, neuropeptide Y and periodontal tissuein Chinese and English. The included articles focused on the effect of various neuropeptides on periodontal tissue.
RESULTS AND CONCLUSION:Calcitonin gene related peptide, substance P, vasoactive intestinal peptide, and neuropeptide Y positive nerve fibers are widely distributed in periodontal support tissues. When sensory nerves are damaged, the target cel s in periodontal tissues are influenced due to changes of nerve fibers distribution and neuropeptide release. They also play a role in the reconstruction of alveolar bone, immune function of periodontal ligament and periodontal tissue. This evidence shows that neuroendocrine factors are closely linked with periodontal tissue. However, these studies concentrated in the animal models for orthodontic and fracture, the effect of the neurotransmitters such as neuropeptides on periodontal disease and the mechanisms need further exploration.
