The Role of Osteoimmunology in Periodontal Disease

Abstract EN

Periodontal disease is a pathological condition that involves inflammation of the tooth supporting structures.

It occurs in response to the presence of bacterial plaque on the tooth structure.

The host defense system, including innate and adaptive immunity, is responsible for combating the pathologic bacteria invading the periodontal tissue.

Failure to eradicate the invading pathogens will result in a continuous state of inflammation where inflammatory cells such as lymphocytes, PMNs, and macrophages will continue to produce inflammatory mediators in an effort to destroy the invaders.

Unfortunately, these inflammatory mediators have a deleterious effect on the host tissue as well as foreign microbes.

One of the effects of these mediators on the host is the induction of matrix degradation and bone resorption through activation of proteases and other inflammatory mediators that activate osteoclasts.
