Periodontal disease is a chronic, progressive bacterial infection and inflammatory condition that affects the supporting structures of the teeth. Left untreated, it can lead to tooth mobility, tooth loss, and is linked to systemic issues like diabetes and cardiovascular disease.
Source: NCBI (.gov)1. Details of Periodontal Disease
- Cause: The primary cause is dental plaque. If not removed, it hardens into tartar (calculus), which requires professional cleaning.
- Pathogenesis: Bacteria release toxins causing inflammation. The immune response, while fighting bacteria, inadvertently destroys connective tissue and jawbone.
- Characteristics: Often painless in early stages; manageable but not fully curable once structural support is lost.
2. Properties of Periodontal Tissues
The periodontium consists of four specialized tissues:
- Gingiva (Gums): The soft tissue barrier protecting underlying bone.
- Periodontal Ligament (PDL): Fibers that attach the root to the bone, acting as a shock absorber.
- Cementum: Mineralized substance on the root surface for ligament anchoring.
- Alveolar Bone: The jawbone that supports the tooth roots.
3. Function of Periodontal Tissues
A healthy periodontium works to:
- Anchor the Teeth: Securely hold teeth within the jaw.
- Protect the Root: Prevent decay and sensitivity.
- Provide Sensory Info: Act as receptors for biting forces.
- Enable Mastication: Maintain stability during eating.
4. Kinds and Stages of Periodontal Disease
A. Gingivitis (Mild, Reversible)
Inflammation limited to the gingiva. Symptoms include red, puffy gums that bleed easily. This stage is completely reversible with proper hygiene.
B. Periodontitis (Irreversible Stage)
Bacteria seep below the gum line, destroying ligament and bone. Symptoms include gum recession, "long" teeth, and loose teeth.
- Stage I (Initial): Bone loss <15%.
- Stage II (Moderate): Bone loss 15%–30%.
- Stage III (Severe): Significant bone loss; high risk of tooth loss.
- Stage IV (Advanced): Extensive loss; potential loss of all teeth.
C. Other Specific Conditions
- Necrotizing Periodontal Disease: Severe, painful infection causing tissue death.
- Systemic Manifestation: Disease associated with issues like diabetes or leukemia.
- Periodontal Abscess: Localised, purulent infection.
