Clinical Features of Gingivitis

Stages of Gingivitis

Initial Lesion:
in 2-4 days, gingiva is infiltrated by PMNs, increase in gingival crevicular fluid, vascular dilatation.
 
Early lesion:
in 4-7 days, gingiva is infiltrated by Lymphocytes, erythematous, bleeds upon probing, vascular proliferation
 
Established lesion:
in 14-21 days, gingiva is infiltrated by Plasma cells, increase bleeding and vascular proliferation
 

Stages of Gingivitis

Localized or Generalized  
Marginal, Papillary, or Diffuse  

Color Changes in Gingivitis

Important clinical sign of gingival disease  
Normal: coral pink  
Chronic inflammation intensifies the red or bluish red color  
Change in color is due to vascular proliferation and reduction of keratinization  
Changes start in the interdental papillae and gingival margin and spread to attached gingiva  

   

Gingival Bleeding

Bleeding on gentle probing and increase gingival crevicular fluids are the two earliest signs of gingival inflammation  
Gingival bleeding varies in severity, duration, and the ease with which it is provoked.  
Bleeding on probing appear earlier than change in color or other visual signs  
It is more sensitive sign than change in color  
Bleeding can be provoked by mechanical trauma (e.g. from toothbrushing, toothpicks, or food impaction) or by biting into solid foods such as apples  
The severity of bleeding and the ease with which it is provoked depend on the intensity of inflammation  

   

 

Mild inflammation

 

Moderate inflammation

 

Severe inflammation

Gingival Bleeding

Gingival bleeding without other signs of gingival inflammation or which is persistent after treatment should be carefully investigated for the presence of systemic diseases or disorders.

Abnormal gingival bleeding may be seen in the following disorders:

Vascular abnormalities (e.g. Vita. C def.)  
Platelet disorders (Thrombocytopenia purpura)  
Hypoprothrombinemia (Vita. K def.)  
Excessive amount of NSAID or anticoagulants  
Hemophilia  
Leukemia  

Change in Consistency

Normally: the gingiva is firm and resilient  
With inflammation, the gingiva becomes spongy, edematous and friable  
The change in consistency is due to degeneration of connective tissue and epithelium with vascular proliferation and increase in extra cellular fluids volume  


Change in Texture

Normally: the gingiva is stippled  
Loss of stippling is an early signs of gingivitis  
The surface is smooth and shiny due to epithelial atrophy  


 

Change in size

Associated mainly with gingival enlargement  
Marginal, Papillary, or Diffuse  

 

Oral Hygiene Evaluation

One of the most important steps in clinical examination is evaluation of the patient oral hygiene  
Disclosing solutions can be used to detect plaque  
The amount of plaque not necessarily related to the severity of the disease present  

Oral Hygiene Evaluation

There are two ways to evaluate oral hygiene:


Measure the distribution of plaque  
Measure the amount of plaque
