Periodontal disease is a type of disease that affects one or more of the periodontal tissues:

Other research areas include the development and evolution of tooth enamel and periodontal tissues as well as craniofacial tissue engineering.

There are four types of abscesses associated with the periodontal tissues:

Bleck used a gnathodynamometer and also found out the close relation between periodontal tissue and masticatory force.

Dr. Morill worked more deeply on the relationship between masticatory muscles and pain signals from the periodontal tissue in different ways.

Dr. Bleck found out that periodontal tissue is an important issue, which impact the amount of force in individuals.

Dr. Morill found out that masticatory muscles will stop their contraction by appearance the first pain signals from the periodontal tissue differently.

One example involves the recovery of periodontal tissues by separating oral epithelial cells and gingival connective tissues from the treated root surface.

It is generally a systemic disease which may involve the periodontal tissue, the upper and lower respiratory tract, kidneys, middle ear, and female genitalia.

Thus it represents the junction of the pulp and the periodontal tissue.
