Periodontitis

Definition

Periodontitis is a serious gum infection that damages the soft tissue and destroys the bone supporting your teeth. It is caused by bacterial accumulation and can lead to tooth loss if untreated.

5 Must Know Facts For Your Next Test

1. Periodontitis is primarily caused by Gram-negative anaerobic bacteria such as Porphyromonas gingivalis.
2. The progression of periodontitis involves the formation of periodontal pockets due to inflammation and detachment of gums from teeth.
3. Risk factors include poor oral hygiene, smoking, genetic susceptibility, and certain systemic diseases like diabetes.
4. It triggers an inflammatory response that leads to the destruction of the connective tissues and alveolar bone.
5. Treatment often involves scaling and root planing, antibiotics, and in severe cases, surgical interventions.
