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.
