  1. Gingival Disease Nield-Gehrig CH 10 Perry CH 6

  2. Gingival Description

  3. 6 Gingival Characteristics • Color • Size • Position of margin • Shape of margins and papillae • Texture and consistency • Bleeding and/or exudate

  4. Learning to Look at the Gingiva

  5. Healthy Gingiva • Tissue fits snugly around the tooth • Pointed papillae fill embrasure spaces • Firm and resilient • Little or no gingival crevicular fluid (GCF)

  6. Normal Variations of Color

  7. Gingivitis • The mildest and most common form of periodontal disese • Gingivitis – inflammation of the gingiva causing tissue to become edematous and erythematous…bleeds easily on provocation.

  8. Tissue Color In Gingivitis • Acute inflammation = increased blood flow = RED tissue • Chronic inflammation = bluish-red or purplish – red

  9. Changes in Disease

  10. Gingival Bleeding on Probing • The two earliest signs of ginigval inflammation preceding established gingivitis are: • 1. Increased gingival crevicular fluid production rate • GCF = inflammatory exudate • Recently – development of tests for the detection or prediction of periodontal disease using the components, origin, and function of GCF • Drugs in GCF – tetracycline and Metronidazole • 2. Bleeding from the gingivl sulcus on gentle probing

  11. Gingival Bleeding • In gingival inflammation, histopathologic alterations that result in abnormal gingival bleeding include dilation and engorgement of the capillaries and thinning or laceration of the sulcular epithelium. • Because the capillaries are engorged and closer to the surface, and the thinned, degenerated epithelium is less protective, stimuli that are normally innocuous cause rupture of the capillaries and gingival bleeding. • The severity of the bleeding and the ease of its provocation depend on the intensity of the inflammation. • In cases of moderate or advanced periodontitis, the presence of bleeding on probing is considered a sign of active tissue destruction.

  12. Gingival Bleeding Associated with Systemc Changes • In some systemic disorders, gingival hemorrhage occurs spontaneously or after irritation and is excessive and difficult to control. • Vascular abnormalities – Vit. C deficiency or allergy • Platelet disorders – thrombocytopenic purpura • Hypprothrombinemia – Vit. K deficiency • Other coagulation defects – hemophilia, leukemia, • Deficient platlet thromboplastic factor (PF3) resulting from uremia, multiple myeloma and ostrubella purpura.

  13. Gingival Bleeding Associated with Systemc Changes • Hormonal replacement therapy • Oral contraceptives • Pregnancy • Menstral cycle • Diabetes • Medications: • Anticonvulsants • Antihypertensive calcium channel blockers • Immunosuppressant drugs • aspirin

  14. Change in Sizein disease

  15. Tissue Size in Gingivitis • Increase in tissue fluid causes enlargement of the marginal and interproximal gingival tissues (Edema) • Change can be localized to a few areas or affect the whole mouth (generalized)

  16. Change in Position in Margin

  17. Change in Position of Margin

  18. Change in Shape of Margin

  19. Bulbous Papilla

  20. Cratered Papilla

  21. Missing and Blunted Papilla

  22. Changes in the Consistency In Gingival Disease • Both chronic and acute inflammations produce changes int the normal firm and resilient consistency of the gingiva. • Chronic gingivitis = edematous – (destructive) and fibrotic – (repairative) changes coexist • The consistency of the gingiva is determined by their relative pedominance.

  23. Spongy Tissue

  24. Surface Texture Changes in Disease • The surface of normal gingiva usually exhibits numerous small depressions and elevations = stippling • In chronic inflammation the surface is either smooth and shiny or firm and nodular • This depends on whether the dominant changes are exudative or fibrotic

  25. Smooth, Shiny Tissue • Can be: • exudative • Epithelial atrophy in atrophic gingivitis • Chronic desquamative gingivitis can also have peeling of the surface

  26. Smooth, Shiny Tissue

  27. Changes in surface texture chronic gingivitis • Hyperkeratosis results in a leathery texture (example = chronic gingival disease in a smoker) • Fibrotic = firm nodular • Drug induced gingival overgrowth also produces a nodular surface

  28. Nodular Tissue

  29. Assess the Following • Color • Size • Position of gingival margin • Shape of margins and papillae • Use air and probe to determine texture • Consistency • Check for bleeding

  30. More on Size • Gingival Enlargement or gingival overgrowth are the current terms used to describe an increase in the size of the gingiva • “hypertrophic gingivitis” or “gingival hyperplasia” may have erroneous pathologic connotations • Gingival enlargement is a purely clinical term

  31. Gingival enlargement can beclassified according to etiologic factors and pathologic changes • I. Inflammatory enlargement • A. Chronic • B. Acute • II. Drug-induced enlargement • III. Enlagements associated with systemic diseases or conditions • IV. Neoplastic enlargement (gingival tumors) • V. False enlargement

  32. Criteria of location • Localized: limited to the gingiva adjacent to a sengle tooth or group of teeth. • Generalized: involving the gingiva throughout the mouth • Marginal: confined to the marginal gingiva • Papillary: Confined to the interdental papillae • Diffuse: Involving the marginal and attached gingivae and papillae. • Discrete: An isolated sessile or pedunculated, tumorlike enlargement.

  33. Non-Plaque –Induced Gingival diseases • Bacterial origin – • Neisseria gonorrhea – associated lesions • Treponema pallidum – associated lesions • Streptococcal species – associated lesions • RARE – Non-plaque is RARE

  34. Non-Plaque-induced gingival diseases of viral origins • RARE – Non-plaque is RARE • Acute herpetic gingivostomatitis • Recurrent oral herpes • Varicella-zoster infections

  35. Primary Herpetic Gingivostomatitis • Caused by herpes simplex virus type 1 (HSV-1) • Most often occuring in infants and children under 6 years • In most people the primary infection is asymptomatic • As part of the primary infection, the virus ascends through sensory and autonomic nerves, where it persists as latent HSV in neuronal ganglia that innervate the site • In 1/3 of the world’s population secondary manifestations result from various stimuli

  36. NUG • Punched-out, craterlike depressions at the crest of the interdental papillae • Gray, pseudomembranous slough • Linear erythema • Spontanious gingival hemorrhage • Fetid odor

  37. Gingival Diseases Modified by Malnutrition • Most clinical studies have not shown a relationship between the development of gingival diseases and malnutrition with the possible exception of severe vitamin C deficiency.

  38. Lichen Planus • Inflammatory mucocutaneous disorder that may involve mucosal surfaces and the skin. • Current evidence suggests that lichen planus is an immunologically mediated mucocutaneous disorder in which host T lymphocytes play a central role.
