Viral Diseases of the Oral Mucosa in Pediatric Dentistry: Symptoms, Diagnosis, and Treatment - Comparative Table 📊

Oral medicine

Viral diseases affecting the oral mucosa are frequent in pediatric dentistry and often present diagnostic and therapeutic challenges. The most common conditions include primary herpetic gingivostomatitis (HSV-1), hand-foot-mouth disease (HFMD, caused by Coxsackie and enteroviruses), and herpangina. Other relevant viral infections include varicella-zoster virus (VZV), Epstein–Barr virus (EBV), and cytomegalovirus (CMV).

1. Major Viral Oral Diseases in Children

1.1 Primary Herpetic Gingivostomatitis (HSV-1)

➤ Signs and symptoms: Painful vesicles and ulcers on gingiva, lips, and oral mucosa; fever, malaise, cervical lymphadenopathy, and refusal to eat or drink, increasing the risk of dehydration.
➤ Diagnosis: Mainly clinical. In uncertain cases, PCR, viral culture, or Tzanck smear may be used.
➤ Treatment: Oral acyclovir (40–80 mg/kg/day in 3–4 doses for 7–14 days) is the drug of choice. Valacyclovir or famciclovir are options for recurrences. Topical antivirals are less effective.
➤ Clinical features: Highly contagious; recurrences are common and may benefit from daily prophylaxis in selected cases.

1.2 Hand-Foot-Mouth Disease (HFMD)

➤ Signs and symptoms: Painful ulcers (2–4 mm) on tongue, gingiva, and palate; accompanied by papules and vesicles on hands and feet; fever and malaise are common.
➤ Diagnosis: Clinical. In atypical presentations, throat or stool samples may confirm viral etiology.
➤ Treatment: No specific antiviral therapy exists. Management includes analgesics (acetaminophen, ibuprofen), hydration, and topical anesthetics for oral pain. Aspirin should be avoided in children.
➤ Clinical features: Self-limiting, resolving within 7–10 days. High transmissibility in children under 5 years of age.

2. Other Viral Infections of the Oral Cavity
Other less frequent but clinically relevant infections include varicella-zoster (chickenpox and herpes zoster), infectious mononucleosis (EBV), CMV infections, and oral papillomavirus lesions. These conditions may present with vesicles, erythematous patches, or papillary growths such as squamous papilloma and focal epithelial hyperplasia.

3. Diagnostic Considerations
A careful evaluation of lesion distribution, systemic symptoms, and medical history is crucial. In complex or atypical cases, laboratory tests such as PCR, serology, or biopsy may be required to confirm viral etiology.

4. Management and Pharmacological Interventions

° Herpangina & HFMD: Supportive care with analgesics and hydration.
° HSV-1: Oral acyclovir remains the gold standard; valacyclovir and famciclovir are effective alternatives in adolescents and recurrent cases.
° Other viral infections: Generally self-limited; antiviral therapy is rarely required, except in immunocompromised patients or severe cases.

Causes (Etiology)
Herpangina is caused primarily by Coxsackievirus A, though other enteroviruses like Coxsackie B and echoviruses may also be responsible. These viruses spread easily through:

° Fecal-oral route
° Respiratory droplets
° Contaminated surfaces (e.g., toys, utensils)

Outbreaks are common in daycare centers and preschools (Khetsuriani et al., 2006).

Symptoms and Clinical Features
The condition develops rapidly and typically includes:

° High fever (101–104°F / 38.5–40°C)
° Sore throat and painful swallowing
° Loss of appetite
° Irritability
° Abdominal pain (occasionally)

➤ Oral findings appear within 24–48 hours:

° Small, fluid-filled blisters (1–2 mm) on the soft palate, uvula, and tonsils
° Blisters rupture into shallow ulcers with red halos
° Symptoms usually resolve in 5 to 7 days

Unlike hand, foot, and mouth disease, herpangina typically does not involve skin rashes or lesions on the hands and feet (Puenpa et al., 2019).

Treatment
There is no specific antiviral medication for herpangina. Treatment focuses on supportive care:

➤ Hydration: Encourage frequent sips of water or electrolyte solutions
➤ Pain relief: Acetaminophen or ibuprofen for fever and sore throat
➤ Soft, cold foods: Popsicles, smoothies, and yogurt to reduce discomfort
➤ Avoid acidic or spicy foods: These may worsen oral pain

Prevention
Key preventive strategies include:

° Frequent handwashing with soap and water
° Avoiding the sharing of utensils or cups
° Disinfecting surfaces and toys
° Keeping infected children home during the contagious period

There is no vaccine specifically for herpangina, though vaccine research targeting certain enteroviruses is ongoing in high-incidence regions.

💬 Discussion
While herpangina is generally mild, it can be distressing for both children and parents due to painful symptoms and feeding difficulties. In some cases—especially in younger children—dehydration may require medical attention. Additionally, misdiagnosis can lead to inappropriate use of antibiotics, contributing to antibiotic resistance.
Public health education for caregivers and accurate clinical guidance are essential to avoid unnecessary treatments and improve patient outcomes. Healthcare providers should offer clear instructions for at-home care and signs that warrant medical evaluation.

💡 Conclusion
Herpangina is a self-limiting viral illness in children caused by enteroviruses such as Coxsackievirus A. It presents with fever, sore throat, and ulcers in the back of the mouth. Management is supportive, focusing on hydration and pain relief. Understanding its symptoms, transmission, and proper care helps reduce complications and prevents unnecessary medical interventions.

Herpangina: Infección común en los niños

Herpangina

La herpangina es una de las patologías mas comunes entre los niños, en especial en la edad lactante, es contagiosa y se evidencia con pequeñas pápulas (1-2 mm) en la cavidad bucal.

Que los hijos crezcan sanos y fuertes es lo que todos los padres desean. No obstante, no podemos pasar por alto que es casi inevitable que en algún momento enfermen. De ahí que sea necesario que los adultos sepan reaccionar y actuar convenientemente. Y eso es algo que se logra, por ejemplo, conociendo que patologías son frecuentes en la infancia. Precisamente por eso les puede ser útil saber qué es la herpangina.

A continuación, vamos a exponer todos los aspectos más relevantes que hay que conocer al respecto de la misma:

¿Qué es y qué la causa?

Lo primero que hay que tener claro es que se trata de enfermedad viral o infección muy habitual entre los niños que poseen edades comprendidas entre los 3 y los 10 años. La causa un virus, el Coxsackie del grupo A, que resulta contagioso además, de ahí que sea frecuente que pueda “propagarse” rápidamente en la guardería e incluso en el colegio o entre hermanos.

Herpangina


Síntomas de la herpangina

La principal señal que indica que un pequeño sufre herpangina es que cuenta con una serie de lesiones en el interior de la boca. Comienzan teniendo la forma de puntos de color rojo que, luego, pasan a ser ampollas y que finalmente, al explotarse, se convierten en pequeñas llagas o úlceras. Estas suelen tener un tamaño aproximado de 3 milímetros y debido a que pueden ser muy dolorosas, traen consigo que el niño no quiera ni comer ni tampoco beber.
No obstante, no hay que pasar por alto que hay otros síntomas que también pueden venir a indicar de manera clara que un menor sufre esta enfermedad. Nos estamos refiriendo a los siguientes:
° Dolor de cabeza
° Fiebre
° Sensación de malestar general
° Dolor al tragar, ya sea un alimento líquido o uno sólido
° Apatía o falta de energía

Tratamiento

Cuando se sospeche que el niño sufre esta infección, lo que hay que hacer es llevarlo al pediatra para que este pueda realizar un diagnóstico. Si este indica que sí, que padece herpangina, le establecerá un tratamiento con el que acabar con la misma. Este se sustentará en los siguientes pilares:

° Es fundamental que el menor beba mucho líquido, aunque lo rechace o le cueste tragarlo. Y es que es la manera de que no se deshidrate.
° De cara a aliviarle las molestias y dolores, le recetará fármacos tales como ibuprofeno y paracetamol.
° Específicamente para lo que es la mejora del estado de la boca, puede prescribirle algún tipo de anestésico tópico.
° El pediatra indicará a los padres que deben prepararle al niño comida que no sea picante, que no esté caliente y también que no sea frita. Eso sin pasar por alto que tampoco es recomendable que tome cítricos y productos que estén demasiado salados, porque le causarán más irritación y dolor en la garganta.
° Se advertirá a los progenitores además que tienen que conseguir que tome más zumos de fruta y más lácteos, ya que contribuirán a acabar con las llagas que pueda tener en el interior de la boca.
° El helado es un producto muy recomendable no solo porque es un lácteo sino porque su frío aliviará las molestias que pueda estar sintiendo.

Otros datos de interés

Además de todo lo indicado, no podemos pasar por alto otra serie relevante de aspectos respecto a la herpangina en pro de que los padres estén informados:

° Por regla general, suele desaparecer en torno a los ocho o diez días.
° Si la fiebre es muy alta, si el pequeño presenta una clara deshidratación, si cuenta con dificultades para respirar o si las llagas llevan cinco días sin mejorar hay que acudir al pediatra. Y es que puede existir alguna complicación que necesite tomar más medidas.
° Aunque en las guarderías y escuelas es complicado tomar medidas en pro de que la enfermedad no se contagie, entre las medidas de precaución y prevención que se pueden desarrollar está el que los pequeños se laven las manos con mucha frecuencia.
° Los niños que sufren esta infección causada por el virus es recomendable que no acudan al centro escolar hasta que no se hayan recuperado por completo. Así se evitará contagiar a otros compañeros.
° La herpangina está muy relacionada con otra patología que es conocida popularmente como mano, pie y boca. Ambas son ocasionadas por un virus de la misma familia. Sin embargo, la segunda, como su propio nombre indica, presenta lesiones no solo en el interior de la boca sino también en las manos y en los pies.
