Classification of Gingivitis
1.Based on Course and Duration
1. Acute Gingivitis
- Sudden onset and short duration
- Can be Painful
- Less severe form is termed as subacute gingivitis
2. Recurrent Gingivitis
- Reappears after having been eliminated by treatment or disappearingspontaneously
3. Chronic Gingivitis
- Slow in onset and of long duration
- Painless unless complicated by acute or subacute exacerbations
- Fluctuating disease in which persists inflammation or resolve andnormal areas become inflamed.
2.Based on Distribution
I. Localized gingivitis
- Confirmed to the gingivaof a single tooth or a group of teeth.
II. Generalized Gingivitis
- Involves the entire mouth
3.Based on site
- Involves the inter dental papillae and after extends into the adjacentportion of gingival margin.
- Papillae into the adjacent portion of gingival margin.
- Earliest signs of gingivitis occur after in papillae due to col whichhas non-keratinized epithelium which is permeable to microorganisms.
- Involves the gingival margin and may include a portion of thecontiguous attached gingiva.
- Affects the gingival margin attached gingival and theinterdental papillae
Localized marginal gingivitis:
- Confined to one or more area of marginal gingiva
Localized diffuse gingivitis:
- Extends from the margin to the mucobuccal fold but is confirmed to thearea.
Localized papillary gingivitis:
- Confirmed to one or more interdental spaces in a limited area
Generalized marginal gingivitis:
- Involves the gingival margin in relation to all teeth.
- The interdental papillae are usually affected;
Generalized diffuse gingivitis:
- Involves the entire gingiva
- The alveolar mucosa and attached gingiva are affected obliterating theMGJ
- Systemic condition may be involved.
