Gingivitis is a term used to describe non-destructive periodontal disease

. In the absence of treatment, gingivitis may progress to periodontitis, which is a destructive form of periodontal disease.

While in some sites or individuals, gingivitis never progresses to periodontitis, data indicate that periodontitis is always preceded by gingivitis.

Classification

As defined by the 1999 World Workshop in Clinical Periodontics, there are two primary categories of gingival diseases, each with numerous subgroups:
  1. Dental plaque-induced gingival diseases.
    1. Gingivitis associated with plaque only/yes or no
    2. Gingival diseases modified by systemic factors
    3. Gingival diseases modified by medications
    4. Gingival diseases modified by malnutrition
  2. Non-plaque-induced gingival lesions
    1. Gingival diseases of specific bacterial origin
    2. Gingival diseases of viral origin
    3. Gingival diseases of fungal origin
    4. Gingival diseases of genetic origin
    5. Gingival manifestations of systemic conditions
    6. Traumatic lesions
    7. Foreign body reactions
    8. Not otherwise specified

s of gingivitis are somewhat non-specific and manifest in the gum tissue as the classic signs of inflammation:
  • Swollen gums
  • Bright red or purple gums
  • Gums that are tender or painful to the touch
  • Bleeding gums or bleeding after brushing


Additionally, the stippling

Cause

Because plaque-induced gingivitis is by far the most common form of gingival diseases, the following sections will deal primarily with this condition.


The etiology, or cause, of plaque-induced gingivitis is bacterial plaque, which acts to initiate the body's host response. This, in turn, can lead to destruction of the gingival tissues, which may progress to destruction of the periodontal attachment apparatus. The plaque

If gingivitis is not responsive to treatment, referral to a periodontist (a specialist in diseases of the gingiva and bone around teeth and dental implants) for further treatment may be necessary.

Prevention

Gingivitis can be prevented through regular oral hygiene

They found that men and women who had calcium intakes of fewer than 500 milligrams, or about half the recommended dietary allowance, were almost twice as likely to have gum disease, as measured by the loss of attachment of the gums from the teeth. The association was particularly evident for people in their 20s and 30s.

Treatment

The focus of treatment for gingivitis is removal of the etiologic (causative) agent, plaque. Therapy is aimed at the reduction of oral bacteria, and may take the form of regular periodic visits to a dental professional together with adequate oral hygiene home care. Thus, several of the methods used in the prevention of gingivitis can also be used for the treatment of manifest gingivitis, such as scaling, root planing, curettage

Recent scientific studies have also shown the beneficial effects of mouthwashes with essential oils.
