Safe Practitioner Framework - LO

Clinical Knowledge and Skills - Assess and manage the health of periodontal and soft tissues taking into account risk, lifestyle factors, plaque control/self-care and compliance/response to advice
Clinical Knowledge and Skills - Monitor and record changes in periodontal health using appropriate methods

### Revision of Inflammation

"itis" means inflammation
Classical signs of acute inflammation include redness, swelling, heat, pain, and loss of function
Acute inflammation is a short-term response to injury or infection, while chronic inflammation is a long-term response that can persist for weeks, months, or even years
Four patterns of inflammation include serous, fibrinous, purulent, and hemorrhagic

Consideration of Health vs Disease

Clinical appearance, histological understanding, and patient symptoms can be used to assess the health of the periodontium

Three Basic States of the Periodontium

Health, Gingivitis, and Periodontitis are the three basic states of the periodontium
Periodontal Diseases are a category of diseases that affect the periodontium

Gingivitis Versus Periodontitis Definition

Gingivitis is a bacterial infection confined to the gingiva, and is reversible
Periodontitis is a bacterial infection of all parts of the periodontium, and is irreversible

Clinical Appearance

Color, Margin, Contour, Bleeding, Consistency, and Texture are all key clinical appearances to consider when diagnosing gingivitis and periodontitis
Bleeding in the gums is not always a sign of disease, but should be investigated.

Clinical Features of Gingival Health, Gingivitis, and Periodontitis

Healthy Gingiva:
- Uniform pink color with possible pigmentation variations
- Knife-edge margins at the gingival margin (GM) and pointed interdental papilla (IDP)
- Firm consistency, smooth or stippled texture
- No bleeding upon probing
- Margin slightly coronal to the cementoenamel junction (CEJ), with probing depths of 1-3mm
Gingivitis:
- Red color due to inflammation
- Rolled, thickened gingival margins, rounded or blunted IDP
- Spongy, loose, or boggy consistency
- Shiny, stretched texture
- Bleeding present upon probing
- Margin coronal to CEJ (due to swelling), increased probing depth (>3mm) but no apical migration of the JE
Periodontitis:
- Oedematous (bluish/purple) or fibrotic (pink, nodular) color
- Loss of knife-edge margins, IDP may be lost or cratered
- Spongy or fibrotic consistency
- Shiny or nodular texture
- Bleeding and suppuration present
- Margin apical to CEJ with deeper probing depths (4mm+), indicating a true pocket caused by the apical migration of the JE.

Histological Presentation

Healthy Gingiva:
- Junctional Epithelium (JE) firmly attached to enamel, located coronal to the CEJ.
- Intact supragingival fibre bundles support the JE.
- Intact alveolar bone located 2-3mm apical to the JE.
- Intact Periodontal Ligament (PDL) connects the tooth root to the alveolar bone.
Gingivitis:
- JE still attached to enamel, but extends epithelial ridges into connective tissue.
- Reversible damage to supragingival fibre bundles.
- No alveolar bone destruction.
- No progression into the PDL.
Periodontitis:
- Apical migration of the JE below the CEJ, attaching to cementum.
- Permanent destruction of gingival fibers with epithelial growth preventing reinsertion.
- Permanent alveolar bone loss.
- Permanent destruction of some or all PDL fibers.

Key Definitions

False Pocketing: Enlarged gingiva without apical migration of the JE, resulting in increased probing depth without true periodontal destruction.
True Pocketing: Apical migration of the JE, leading to deeper pockets and attachment loss, typically seen in periodontitis.
Clinical Attachment Loss: Loss of connective tissue attachment to the tooth characterized by the apical shift of the JE and destruction of periodontal support.

Patient Symptoms

Gingivitis:
- Red, swollen, and bleeding gums, especially when brushing or flossing.
- No pain, as gingivitis is usually painless.
Periodontitis:
- Gum recession leading to visible roots and tooth sensitivity.
- Persistent bad breath (halitosis).
- Tooth mobility or teeth appearing longer due to bone loss.
- Pain, especially when chewing, and possible abscesses.

Additional Considerations

Bleeding gums are not normal and cannot be treated solely with products like Corsodyl.
Plaque must be mechanically removed to resolve gingivitis.
The British Society of Periodontology (BSP) defines a stable periodontal status as less than 10% bleeding sites, a realistic target for patients to aim for.

Collagen in Gingival Health and Disease

Role of Collagen in Healthy Gingiva:
- Collagen (mainly Type I) provides strength and maintains the integrity of gingival tissue.
- Collagen fibers anchor the gum to the tooth and protect the JE from bacterial invasion.
Collagen in Gingivitis:
- Inflammation causes the release of enzymes like collagenase, leading to the degradation of collagen fibers.
- Damage to collagen in gingivitis is typically reversible with proper plaque removal and oral hygiene, allowing tissue regeneration.
Collagen in Periodontitis:
- Collagen breakdown extends to the PDL, leading to the loss of tissue attachment and bone support.
- Collagen destruction in periodontitis cannot be reversed, resulting in periodontal pockets and bone loss.
Collagen in Treatment:
- Regenerative therapies like guided tissue regeneration (GTR) use collagen membranes to promote tissue repair in periodontitis.
