Gingival Diseases

Various Stages Of Gingivitis

4 stages of gingivitis:

• Stage I Initial lesion

• Stage II Early lesion

• Stage III Established lesion

• Stage IV Advanced lesion






Gingival Diseases
Initial lesion 2-4 days
Early lesion 4-7 days
Established lesion 14-21 days
dvanced lesion

Classification

I. According to duration:
1. Acute gingivitis
2. Chronic gingivitis


II. According to distribution:
1. Localized gingivitis
2. Generalized gingivitis
3. Marginal gingivitis
4. Papillary gingivitis
5. Diffuse gingivitis

Stage I Gingivitis: The Initial Lesion
--no visible changes
--presence of exudation of fluid from
the gingival sulcus  subclinical gingivitis

--The following features are observed
1. Classic vasculitis of vessels subjacent to
the junctional epithelium.

2. Exudation of fluid from gingival sulcus.

3. Changes in the coronal most portion
Junctional epithelium

4. Increased migration of the leukocytes into t
Junctional epithelium and gingival sulcus.

5. Presence of serum proteins.

6. Loss of perivascular collagen.

Stage II Gingivitis: The Early Lesion
Clinically, erythematous gingiva and
on probing may be evident.

Microscopic features of the early lesion

1. All the changes seen in the initial lesion
continue to intensify.

2. The junctional epithelium may begin to show
the development of rete pegs or ridges

3. Accumulation of lymphocytes
beneath the junctional epithelium.

4. Further loss of collagen fiber network
supporting the marginal gingiva.

5. Fibroblasts show cytotoxic alteration with a decreased
capacity for collagen production.

Stage II Gingivitis: The Early Lesion
Clinically, erythematous gingiva and bleeding
the early lesion include:
1. All the changes seen in the initial lesion
2. The junctional epithelium may begin to show
development of rete pegs or ridges.

Stage III Gingivitis: The Established Lesion

--Same as early lesion, with blood stasis

--Changes are seen in color consistency and surface texture.

--Bluish hue around the reddened gingiva

--Proliferation, apical migration and lateral extension of junctional epithelium

--Atropic areas

--Plasma cells are predominant

--Further loss of collagen.

--Increased enzyme levels like acid and alkaline phosphatase, β glucuronidase
and others.

Stage IV Gingivitis: The Advanced Lesion

The advanced lesion is also known as phase of advanced periodontal breakdown.

The following clinical and microscopic features are seen:

1. Persistence of features described in the established lesion.

2. Extension of the lesion into the alveolar bone and PDL leading
to significant amount of bone loss.

3. Continued loss of collagen.

4. Formation of periodontal pockets.

5. Conversion of bone marrow into fibrous tissue.

6. Presence of almost all the types of inflammatory cells.

Changes in the Position of Gingiva

Normal attachment  CEJ

In disease

Coronally  pseudopocket

Apically  gingival recession


Types

1..Visible

2..hidden

14. Dr Jaffar Raza Syed Page 14

Etiology of Gingival Recession

Plaque-induced gingival inflammation
Faulty tooth brushing
Tooth malpositions
Presence of dehiscence and fenestrations
Smoking
Primary trauma from occlusion
Iatrogenic factors

15. Dr Jaffar Raza Syed Page 15


Clinical Significance of Gingival Recession

1. The exposed root surface may be extremely sensitive.
2. Hyperemia of the pulp may result due to gingival recession.
3. Interproximal recession creates oral hygiene problems
thereby resulting in plaque accumulation.
4. Finally, it is aesthetically unacceptable.
