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 |
