    Study Notes

    Viral Infections

    • Herpetic stomatitis is the most common viral infection of the mouth and is mainly caused by Herpes Simplex Virus type 1 (HSV-1).
    • Herpetic gingivostomatitis is a primary infection, mostly seen in children and young adults.
    • The incubation period for herpetic gingivostomatitis is 5 days, during which patients experience fever, malaise, numerous small vesicles on the oral mucosa, and regional lymphadenitis.
    • Recurrent herpes infections occur in 1/3 of those who have had a primary infection and are characterized by localized symptoms without systemic illness.
    • The most common form of recurrent herpes is herpes labialis.
    • Herpes zoster is the recurrent form of chickenpox.
    • Herpangina is caused by Coxsackie A virus and presents with fever, malaise, anorexia, and sore throat with vesicles on the palate, tonsils, and uvula that rupture leaving small ulcers.
    • Hand, foot, and mouth disease is caused by coxsackie virus A and presents with small ulcers on the gingiva, tongue, palate, buccal mucosa, palms of the hands, and soles of the feet.
    • Infectious mononucleosis (glandular fever) is caused by Epstein-Barr virus (EBV) and presents with fever, pharyngitis, enlarged lymph nodes, and long-lasting malaise.
    • Measles is a viral infection that is more severe in developing countries and presents with Koplik's spots which are pin-point bluish-white spots against an erythematous background found on the buccal mucosa opposite the molar teeth.
    • Hairy Leukoplakia is caused by EBV and presents as non-removable white patches on the lateral borders of the tongue, usually bilaterally.

    Bacterial Infections

    • Syphilis occurs in three stages: primary syphilis, secondary syphilis, and tertiary syphilis.
    • Tertiary syphilis is rare but can lead to oral lesions, such as syphilitic leukoplakia.
    • Tuberculosis is caused by Mycobacterium tuberculosis and can lead to oral lesions, such as chronic, painless undermined ulcers.

    Fungal Infections

    • Oral candidiasis is a common fungal infection that can occur in both a chronic and acute form.
    • Acute atrophic (erythematous) candidiasis presents as red, often painful areas, resembling thrush but without the pseudomembrane.
    • Chronic atrophic candidiasis (denture stomatitis) is commonly found in denture wearers and is characterized by erythema and edema of the covered mucosa.
    • Candidiasis can also be associated with immune deficiencies, such as HIV infection.
    • Deep visceral mycosis is a rare fungal infection that can affect the oral mucosa and is often associated with immune deficiency.

    HIV Infection

    • HIV infection is a viral infection that can lead to AIDS, a condition characterized by opportunistic infections and cancers.
    • Oral manifestations of HIV infection can be categorized into three groups:
    • Group 1: Lesions strongly associated with HIV infection, such as candidiasis, hairy leukoplakia, and HIV-associated periodontal diseases.
    • Group 2: Lesions commonly associated with HIV infection, such as atypical ulceration, idiopathic thrombocytopenic purpura, and salivary gland disorders.
    • Group 3: Lesions possibly associated with HIV infection, such as bacterial infections, fungal infections, melanotic hyperpigmentation, and neurological disturbances.
    • HIV gingivitis (linear gingival erythema) is a characteristic finding in HIV infection and presents as a band of erythema along the gingival margin.

    Other

    • Ramsy Hunt syndrome is caused by herpes zoster and affects the facial and auditory nerves, leading to facial paralysis, painful vesicular eruptions, tinnitus, deafness, vertigo, and loss of taste sensation.
    • Congenital syphilis is a condition that presents with various symptoms, including dental defects, eighth nerve defect, ocular keratitis, saddle nose, and other bone and organ defects.

    Histopathology

    • Histopathology is a valuable tool for diagnosing oral infections, as it allows for the identification of specific characteristics of the infecting organism and the host response.
    • Granulomas are often found in tuberculosis, with characteristically arranged multinucleated giant cells known as Langhans cells.
