Study Notes

Local Risk Factors for Plaque Accumulation

Prominent subgingival restoration margins, such as certain tooth anatomical features, can create areas where plaque accumulates more easily. These restorations can make it difficult to remove plaque effectively.
Oral dryness, also known as xerostomia, reduces the saliva's ability to clean the tooth surfaces, leading to increased inflammation and difficult plaque removal. This condition can be caused by medications, Sjogren's syndrome, and mouth breathing.

Drug Influenced Gingival Enlargements

Various medications have been linked to enlargement of the gingival tissues. These include antiepileptic drugs like phenytoin and sodium valproate, certain calcium channel blockers (e.g., nifedipine, felodipine), immunoregulating drugs (e.g., cyclosporine), and high-dose oral contraceptives.
Plaque bacteria in combination with the drug are crucial for the development of gingival problems due to medication.
Not everyone taking these medications experiences gingival enlargement, suggesting other factors may play a role.

Gingival Diseases: Non-Dental Plaque-Induced

Specific Infections

Bacterial Origin
- Neisseria gonorrhoeae: Sexually transmitted infection that can manifest in the gingival tissues.
- Treponema pallidum: The bacteria responsible for syphilis can affect the gingival tissues.
- Mycobacterium tuberculosis: The bacteria responsible for tuberculosis can lead to gingival lesions.
- Streptococcal gingivitis: This condition is associated with streptococcal bacteria.
- Necrotizing Periodontal Diseases: A destructive condition that causes ulceration and necrosis of the gingival papillae.
Viral Origin
- Coxsackie virus (hand-foot-and-mouth disease): This infection causes oral ulcers and blisters.
- Herpes simplex I & II (primary or recurrent): Herpes simplex causes painful blisters and lesions.
- Varicella zoster (chickenpox & shingles): This virus can affect the oral cavity causing lesions.
- Molluscum contagiosum: This virus can manifest as lesions in the oral area.
- Human papilloma virus: Can cause squamous cell papilloma, condyloma acuminatum, verruca vulgaris, and focal epithelial hyperplasia in the mouth.
Fungal Origin
- Candidosis: This fungal infection can cause several types of lesions in the oral cavity.
- Other Mycoses: Various fungal infections can affect the oral cavity.

Inflammatory and Immune Conditions

Hypersensitivity Reactions
- Contact allergy: This is an allergic reaction to substances like dental materials or other allergens.
Autoimmune Diseases of Skin and Mucous Membranes
- Pemphigus vulgaris: This can lead to desquamative gingivitis and vesiculo-bullous lesions.
- Pemphigoid: This autoimmune disease can cause oral lesions.
- Lichen planus: This disease can affect the oral mucosa and gingiva causing white or red lesions.
- Lupus erythematosus: This disease can affect the gingiva causing swelling, pain, and ulceration.
Granulomatous Inflammatory Conditions
- Crohn's disease: This condition can cause oral lesions, including cobblestone appearance, linear ulcers, and gingival overgrowth.
- Sarcoidosis: This disease can affect the gingiva causing lesions and inflammation.

Reactive Processes

Epulides
- Fibrous epulis: This is a non-cancerous tumor that grows on the gingiva.
- Calcifying fibroblastic granuloma: A type of epulis characterized by calcification.
- Vascular epulis (pyogenic granuloma): A type of epulis with a rich blood supply.
- Peripheral giant cell granuloma: Characterized by giant cells.

Neoplasms

Premalignancy
- Leukoplakia: A white patch in the oral mucosa that is not removable.
- Erythroplakia: A red patch in the oral mucosa that is often associated with cancer.
Malignancy
- Squamous cell carcinoma: This is the most common type of oral cancer that can affect the gingiva.
- Leukemic cell infiltration: This can affect the gingiva.
- Lymphoma: This can cause lesions in the gingival tissue.

Endocrine, Nutritional, and Metabolic Diseases

Vitamin deficiencies
- Vitamin C deficiency (Scurvy): Scurvy is characterized by bleeding, ulceration, and swelling of the gingiva.

Traumatic lesions

Physical/mechanical trauma
- Frictional keratosis: This is a white lesion that is caused by friction from brushing or chewing.
- Mechanically-induced gingival ulceration: This can be resulted from trauma during dental procedures or even through excessive use of toothpicks.
- Factitious injury (self-harm: Lesions caused by self-inflicted injury.
Chemical (toxic) Insults:
- Lesions can be resulted from the use of various chemicals, including etching substances, chlorhexidine, acetylsalicylic acid, cocaine, hydrogen peroxide, dentifrice detergents, paraformaldehyde, or calcium hydroxide.
Thermal insults
- Burns of mucosa: Thermal injuries can cause erythema, sloughing of tissue, vesicles, ulceration, petechiae, or erosion.

Gingival Pigmentation

Melanoplakia: A black or brownish pigmentation of the gingiva that is benign.
Smoker's melanosis: A brown-black pigmentation of the gingiva caused by smoking.
Drug-induced pigmentation (antimalarials, minocycline): Some medications can cause gingival pigmentation.
Amalgam tattoo: This is caused by small particles of amalgam from fillings being embedded in the gingiva.

Future Research Needs

Developing simpler tests, such as salivary tests, to detect early signs of gingival problems.
Determining why some individuals are less susceptible to gum disease than others.
Improving the accuracy of tests for gum disease.
Better understanding the different types of gum disease.
Standardizing the use of periodontal probes to ensure accurate and reliable diagnosis.
