Study Notes

Viral Infections of the Oral Cavity

Common oral viral infections include: Varicella-Zoster, Hand Foot & Mouth disease, Herpangina, Epstein-Barr virus (EBV), Mumps, Measles, and Herpes Simplex.
Viral infections can impact the oral cavity in various ways, with different symptoms and complications.
Understanding these infections is crucial for dental professionals in preventing transmission, managing symptoms, and referring patients appropriately.

Varicella-Zoster (Human Herpes Virus 3)

Varicella-Zoster virus causes Chickenpox and Shingles.
Chickenpox is generally mild and self-managed but can be more serious in adults.
Shingles usually manifests in adults and is a reactivation of the dormant virus.
Both Chickenpox and Shingles are characterized by a vesicular rash.

Hand Foot and Mouth Disease

Primarily caused by Group A Coxsackie viruses.
Common symptoms include malaise and spots on the buttocks and groin.
Transmission occurs via air droplets, coughing, fecal contact, and contaminated objects.
Outbreaks are frequent in nurseries.

Herpangina

Characterized by vesicles in the mouth.
Caused by Coxsackie A virus.
Symptoms include malaise, sore throat, and a seasonal occurrence, particularly during summer.
Transmission occurs through the fecal-oral route and air droplets.
Usually self-managed.

Epstein-Barr Virus (Human Herpesvirus 4)

Most people are infected with EBV in early childhood.
Infection in teenagers or young adults can cause infectious mononucleosis (glandular fever).
EBV becomes dormant and remains in the body throughout life without symptoms.
EBV lives latently in B-lymphocytes.
Humans are the only known host.

Diseases Caused by EBV

Glandular fever
Burkitt’s Lymphoma
Nasopharyngeal carcinoma
Oral Hairy Leukoplasia

Mumps

Often a childhood illness.
It causes parotitis (swelling of the parotid salivary glands).
Complications include pain and swelling of the testicles in males and ovaries in females, temporary hearing loss, viral meningitis, and acute pancreatitis.

Measles (Measles Morbillivirus)

Highly contagious, transmitted through air droplets and surfaces.
Causes a characteristic exanthematous rash, along with symptoms like headache, fever, sore throat, and Koplik’s spots.
Potential complications include stillbirth, miscarriage, vision loss, subacute sclerosing panencephalitis (fatal brain complication), seizures, and encephalitis.

Herpes Simplex (HS1 & HS2)

Typically, HS1 causes lesions above the belt (oral), while HS2 causes lesions below the belt (genital).
Primary infection can result in primary gingivostomatitis, genital herpes, herpetic whitlow, and encephalitis.
Secondary infection often occurs due to triggers such as stress, trauma, sunlight, menstruation, immunosuppression, or fatigue.

Herpes Labialis (Cold Sore)

Often triggered by factors such as stress, trauma, sunlight, menstruation, immunosuppression, or fatigue.
Managing symptoms includes eating cool soft foods, avoiding triggers, using NSAIDs, cold compresses, sunblock, hydration, and rest.

Common Advice for managing Herpes Labialis (Cold Sore)

Isolation
No kissing
No oral sex
Use a tissue
Do not share food, cutlery, or towels
Prevent spread
Good hand hygiene practices
Cleaning practices

General Management of Viral Infections

Recognition of symptoms
Infection control measures
Management of symptoms
Referral to appropriate professionals

HIV

Information on HIV can be found in the Sexually Transmitted Disease lecture.

Common Oral Viral Infections

Herpes Simplex Virus (HSV)
- HSV-1: Primarily causes orofacial lesions (e.g., cold sores).
- HSV-2: Associated with genital lesions.
- Demographics: Both can affect any age group; transmission via contact with infected bodily fluids.
- Primary infection: Often results in gingivostomatitis.
- Secondary infection: Reactivation as cold sores (herpes labialis) triggered by stress, trauma, or immunosuppression.
Varicella-Zoster Virus (VZV)
- Varicella (Chickenpox): Common in children, usually mild with fever and vesicular rash.
- Zoster (Shingles): A reactivation of the virus in adults, causing painful unilateral vesicular rash.
- Ramsay Hunt Syndrome: Rare, involving facial nerve palsy.
Epstein-Barr Virus (EBV)
- Causes Infectious Mononucleosis (Glandular Fever) in teens and young adults.
- Dormant in B-lymphocytes; lifelong latent infection.
- Associated with diseases like Burkitt’s Lymphoma, Oral Hairy Leukoplakia, and Nasopharyngeal Carcinoma.
Mumps Virus
- Causes parotitis (inflammation of the parotid glands), typically in children.
- Complications include orchitis in males and oophoritis in females post-puberty.
Measles Virus
- Highly contagious with symptoms like fever, cough, Koplik's spots, and characteristic rash.
- Can cause severe complications such as encephalitis and subacute sclerosing panencephalitis.
Coxsackie Viruses
- Hand, Foot, and Mouth Disease: Mostly seen in children; causes vesicular eruptions on hands, feet, and inside the mouth.
- Herpangina: Seasonal, mainly occurring in the summer, characterized by oral vesicles and malaise.

Signs and Symptoms of Viral Oral Infections

Herpes Simplex: Cold sores, gingivostomatitis.
Varicella-Zoster: Fever, rash (Chickenpox), painful unilateral vesicles (Shingles).
Epstein-Barr Virus: Sore throat, swollen lymph nodes, fatigue (Mononucleosis).
Mumps: Parotitis (swollen parotid glands), fever.
Measles: Fever, rash, Koplik’s spots in the mouth.
Coxsackie Viruses: Oral vesicles, malaise (Herpangina); vesicles on hands and feet (Hand, Foot, and Mouth Disease).

Managing Viral Oral Infections

Symptomatic Treatment:
- Use of NSAIDs (e.g., ibuprofen) for pain relief.
- Cold compresses, hydration, and rest.
- Avoidance of triggers (for herpes) like stress and sun exposure.
- Isolation and hygiene measures (especially for highly contagious infections like measles and mumps) to prevent spread.
- Patient education on avoiding spread (e.g., not sharing utensils or towels, hand hygiene).
Postponing Treatment for Herpes Labialis (Cold Sores):
- Dental treatment should be postponed if active herpes labialis is present to prevent further spread of the virus and to avoid exacerbating the lesion.

Impact on Dental Clinicians

Infection Control:
- Dental professionals must practice strict infection control measures, including personal protective equipment (PPE) and decontamination of instruments, to avoid transmission of viruses like HSV and Coxsackie.
Staff Protection:
- Education and vaccination (e.g., for MMR – measles, mumps, rubella) are crucial to protect the dental team.
Recognition and Referral:
- Early identification of viral infections can lead to timely management, reducing the risk of complications.
