What are the three parts of periodontal tissue?

From childhood to adulthood, teeth occupy a very important part in our lives, but many people tend to neglect dental health. Once suffering from dental diseases, patients often feel painful, and then they begin to pay attention to the impact of dental health on the human body. The periodontal tissue is mainly divided into three parts. Different parts are responsible for different areas and have different disease problems. So what are the three main parts of the periodontal tissue?

Periodontal disease classification

① Gingivitis: acute gingivitis (acute necrotizing ulcerative gingivitis, gingivopapillitis, acute multiple gingival abscesses), chronic gingivitis (simple gingivitis, hypertrophic gingivitis, adolescent gingivitis, pregnancy gingivitis).

② Gingival hyperplasia (drug-induced gingival hyperplasia, hereditary gingival fibromatosis).

③Periodontitis: adult periodontitis (simple periodontitis, combined periodontitis), juvenile periodontitis (diffuse, localized), rapidly progressive periodontitis, prepubertal periodontitis, periodontitis associated with systemic diseases (Down syndrome, diabetic periodontitis). Gingivitis refers to a group of diseases that occur in the gingival tissue without invading other periodontal tissues. Gingival hyperplasia refers to non-inflammatory hyperplasia of the gums caused by certain factors other than local stimulation. Periodontitis is a chronic inflammatory destructive disease that invades the gums and periodontal supporting tissues. Its main characteristics are the formation of periodontal pockets and inflammation of the pocket walls, alveolar bone resorption and gradual loosening of teeth. It is the main cause of tooth loss in adults.

The 1989 World Symposium on Clinical Periodontology classified periodontal disease into:

①Adult periodontitis.

② Early-onset periodontitis: prepubertal diffuse or localized periodontitis, juvenile diffuse or localized periodontitis, and rapidly progressive periodontitis.

③Periodontitis associated with systemic diseases, including Down syndrome, type 1 diabetes, AIDS, etc.

④Necrotic ulcerative periodontitis (necrotizing ulcerative periodontitis).

⑤Refractory periodontitis.
