✅ What Is Angular Cheilitis?
Angular cheilitis is inflammation at one or both corners of the mouth. It is not caused by a virus. Instead, it usually develops when moisture collects in the skin folds at the lip corners, allowing fungi or bacteria to grow.

Common Causes
▪️ Saliva pooling at the corners of the mouth
▪️ Ill-fitting dentures
▪️ Lip licking or drooling
▪️ Nutritional deficiencies (iron, vitamin B12)
▪️ Weakened immune system
The most frequent microorganisms involved include Candida albicans and Staphylococcus aureus.

Typical Symptoms
▪️ Redness and cracks at the lip corners
▪️ Burning or soreness
▪️ White or softened skin in the area
▪️ Mild bleeding when opening the mouth
Angular cheilitis is not contagious.

✅ What Is Oral Herpes (Cold Sores)?
Oral herpes is caused by the herpes simplex virus type 1 (HSV-1). Once infected, the virus remains in the body in a dormant state and may reactivate during stress, illness, or sun exposure.
According to the World Health Organization, HSV-1 infection is highly prevalent worldwide.

Typical Symptoms
▪️ Tingling or burning sensation before lesions appear
▪️ Small fluid-filled blisters
▪️ Clusters of painful sores
▪️ Crusting after the blisters break
▪️ Possible fever or swollen lymph nodes (especially in first infection)
Oral herpes is contagious, particularly during active blister stages.

✅ How to Differentiate Them at Home

Consider the Location
If the lesion is limited strictly to the mouth corners and appears as a crack, it is more likely angular cheilitis.
If you see small grouped blisters, especially on the lip border, it is more consistent with herpes simplex infection.

Notice the Sensation Before It Appears
A tingling or burning feeling before sores develop strongly suggests herpes.

Evaluate Recurrence Pattern
Repeated outbreaks in the same spot, triggered by stress or fever, are typical of herpes.

PDF 🔽 Management of Angular Cheilitis in children ... Angular Cheilitis occurs more in children and it is caused by children sensitivity against certain contact agents like toys, foods, sunlight, allergy against medicines, cosmetics, and long term antibiotic treatment.

💬 Discussion
Although both conditions affect the lips, they are biologically different. Misdiagnosing angular cheilitis as herpes may lead to unnecessary antiviral use. Conversely, assuming herpes is simple irritation may delay effective treatment and increase transmission risk.
Careful evaluation of lesion appearance, symptoms before onset, and recurrence history usually allows correct identification. When uncertainty exists, professional dental or medical evaluation is recommended.

🎯 Recommendations
▪️ Do not self-medicate with antivirals unless herpes is strongly suspected.
▪️ Keep the lip corners dry and protected if angular cheilitis is likely.
▪️ Seek professional evaluation if lesions persist longer than two weeks.
▪️ Maintain balanced nutrition to prevent deficiency-related angular cheilitis.
▪️ Avoid sharing utensils or close contact during active herpes outbreaks.

✍️ Conclusion
Angular cheilitis and oral herpes are distinct conditions with different causes, treatments, and levels of contagion. Angular cheilitis presents as cracks at the lip corners and is usually linked to moisture and fungal or bacterial growth. Oral herpes presents as painful fluid-filled blisters caused by HSV-1 and is contagious.
Recognizing the differences ensures appropriate treatment, reduces discomfort, and prevents unnecessary medication use.

✅ Introduction
Oral ulcerations are a frequent complaint in dental and medical practice. Canker sores, medically known as recurrent aphthous stomatitis (RAS), affect approximately 20% of the general population (Scully & Porter, 2008). These lesions are non-contagious, unlike herpes labialis, and usually heal spontaneously within 7–14 days.
The accurate identification of oral lesions is essential since they may be early signs of systemic conditions such as Crohn’s disease, celiac disease, or autoimmune disorders. Understanding their etiology and therapeutic options helps clinicians manage pain and reduce recurrence.

📌 Recommended Article :

Dental Article 🔽 Oral Manifestations of Systemic Diseases: Updated Clinical Review ... Due to its high vascularity and immune role, the oral cavity frequently reflects systemic conditions. In modern dentistry, recognizing these signs is key to preventive care and interdisciplinary treatment.

✅ Etiology
The exact cause of canker sores remains unclear, but several predisposing factors have been identified:

▪️ Local trauma (e.g., toothbrush injury or orthodontic appliances)
▪️ Nutritional deficiencies (vitamin B12, folate, iron)
▪️ Hormonal fluctuations
▪️ Stress and anxiety
▪️ Food sensitivities, particularly to acidic or spicy foods
▪️ Genetic predisposition
▪️ Immune dysregulation

In contrast, cold sores (herpes labialis) are caused by the Herpes Simplex Virus type 1 (HSV-1), which remains dormant in the trigeminal ganglion and can reactivate under stress or immunosuppression.

✅ Pharmacologic Management
Treatment focuses on symptom relief, promoting healing, and preventing recurrence.

1. Topical medications
▪️ Chlorhexidine mouthwash (Peridex® 0.12%) – reduces bacterial load and secondary infection.
▪️ Corticosteroid gels such as triamcinolone acetonide 0.1% (Kenalog in Orabase®) – decreases inflammation.
▪️ Lidocaine 2% gel (Xylocaine®) – provides local anesthesia and pain relief.

2. Systemic therapy (for severe cases)
▪️ Colchicine (Colcrys®) or Dapsone for recurrent major aphthae.
▪️ Thalidomide (in immunocompromised patients) under strict supervision due to teratogenic risks.

3. Nutritional and preventive therapy
▪️ Supplementation with vitamin B12 (cyanocobalamin), iron, and folic acid may reduce recurrence.
▪️ Avoiding acidic foods, sodium lauryl sulfate toothpastes, and stress is strongly recommended.

📊 Comparative Table: Differential Diagnosis of Oral Ulcers

Condition	Key Features	Distinguishing Signs
Canker Sores (Aphthous Ulcers)	Painful, shallow ulcers with red border; appear on movable mucosa.	Non-contagious; heal within 1–2 weeks.
Cold Sores (Herpes Labialis)	Grouped vesicles that crust; often on lips or fixed mucosa.	Caused by HSV-1; contagious; preceded by tingling sensation.
Oral Lichen Planus	White reticular patches with occasional erosions.	Chronic autoimmune condition; confirmed by biopsy.
Oral Candidiasis	White curd-like plaques that can be wiped off.	Associated with Candida infection; responds to antifungals (Nystatin®).
Traumatic Ulcer	Solitary ulcer with irregular borders.	Linked to local mechanical injury.

💬 Discussion
Differentiating canker sores from other oral lesions is essential to avoid misdiagnosis and inappropriate treatment. Many patients mistake them for herpes infections, which leads to unnecessary antiviral use. Topical corticosteroids and antiseptics remain the first-line management for aphthous ulcers, while antivirals such as acyclovir (Zovirax®) are reserved for herpetic infections.
New research explores low-level laser therapy (LLLT) as a non-invasive method to reduce pain and accelerate mucosal healing (El-Sharkawy et al., 2022).

🔎 Recommendations

▪️ Use topical corticosteroids at the first sign of ulceration.
▪️ Maintain good oral hygiene with alcohol-free mouthwashes.
▪️ Avoid trigger foods and manage stress levels.
▪️ Refer persistent or atypical lesions (>2 weeks) for biopsy to rule out malignancy.

✍️ Conclusion
Canker sores and other mouth ulcers share similar symptoms but differ in etiology, contagiousness, and treatment. Early identification and evidence-based management help patients achieve faster healing and reduced recurrence. Dental professionals play a key role in differential diagnosis, prevention, and patient education.

1. Principales enfermedades virales de la mucosa oral en pediatría

1.1 Gingivoestomatitis herpética primaria (HSV-1)
➤ Signos y síntomas: Vesículas dolorosas sobre mucosa oral, encías, labios; fiebre, malestar general, adenopatías; posible rechazo a la ingesta e incluso deshidratación.
➤ Diagnóstico: Clínico; en casos dudosos, se confirma mediante PCR, cultivo viral, inmunofluorescencia o test de Tzanck.
➤ Tratamiento: Acyclovir oral (40–80 mg/kg/d en 3-4 tomas por 7–14 días), valacyclovir o famciclovir en recurrencias; tópicos (aciclovir, docosanol) son menos efectivos.
➤ Características: Alta transmisibilidad; reactivaciones son frecuentes y pueden mejorar con profilaxis diaria.

1.2 Enfermedad mano-pie-boca (HFMD)

➤ Signos y síntomas: Vesículas o úlceras de 2–4 mm en encías, lengua, paladar; también pápulas en manos y pies; fiebre y malestar.
➤ Diagnóstico: Clínico; si es necesario, se hace hisopado faríngeo o muestra fecal para identificar el virus.
➤ Tratamiento: No existe tratamiento curativo—se maneja de forma sintomática: analgésicos (acetaminofén, ibuprofeno); anestésicos tópicos para el dolor; evitar aspirina en niños.
➤ Características: Muy contagiosa, especialmente en menores de 5 años; se autolimita entre 7–10 días

1.3 Herpangina

➤ Signos y síntomas: Fiebre alta, cefalea, odinofagia; tras 1–2 días aparecen vesículas grises en m. blanda orofaríngea, evolucionan a úlceras de ≤5 mm; localizadas en pilares amigdalares, paladar blando, úvula.
➤ Diagnóstico: Clínico, diferenciándose principalmente de HSV por la localización posterior versus anterior.
➤ Tratamiento: Sintomático, orientado a mitigar el dolor; la enfermedad suele resolverse en menos de una semana

5. Discussión
Estas patologías representan parte esencial del ejercicio en odontopediatría. Es clave un diagnóstico preciso, ya que muchas son autolimitadas pero dolorosas, afectando alimentación, calidad de vida y riesgo de complicaciones como deshidratación o sobreinfección bacteriana. La capacidad de distinguir entre herpes, HFMD y herpangina facilita la toma de decisiones sobre tratamiento y manejo domiciliario.
Además, la literatura reciente valida guías diagnóstico-terapéuticas claras; por ejemplo, la revisión y árbol decisional propuestos por Guillouet et al., basados en 20 entidades virales pediátricas. Esto refuerza la importancia de formación continua y herramientas prácticas en odontología infantil.

6. Conclusión
Las principales enfermedades virales de la mucosa oral en odontopediatría —HSV-1, HFMD y herpangina— presentan signos distintivos que permiten diferenciarlas clínicamente. El diagnóstico certero y oportuno facilita un tratamiento sintomático adecuado y previene complicaciones. Acyclovir oral sigue siendo el fundamento para HSV-1, mientras que para HFMD y herpangina, el manejo centrado en analgesia, hidratación y observación es suficiente. Las herramientas diagnósticas recientes enriquecen la práctica clínica. Se recomienda fomentar estrategias preventivas y educación familiar para reducir transmisión y mejorar pronóstico infantil.

✅ Introducción
Las lesiones orales representan un reto diagnóstico en odontología y medicina general. El herpes labial, la estomatitis aftosa y la candidiasis oral son entidades comunes con etiologías distintas: viral, inflamatoria e infecciosa por hongos, respectivamente. Conocer sus signos, síntomas y manejo terapéutico es esencial para un tratamiento adecuado y la prevención de recurrencias.

1. Herpes Labial

➤ Etiología
Causado por el virus del herpes simple tipo 1 (HSV-1).
➤ Signos y síntomas
° Pródromos: ardor, hormigueo o prurito en el labio.
° Lesión típica: vesículas agrupadas en el borde bermellón que evolucionan a úlceras dolorosas y costras.
➤ Diagnóstico
Clínico, basado en la recurrencia y localización. En casos atípicos se emplean pruebas serológicas o PCR.
➤ Tratamiento
° Adultos: antivirales tópicos u orales (aciclovir, valaciclovir).
° Niños: manejo sintomático y antivirales en casos graves.

2. Afta (Estomatitis Aftosa Recurrente)

➤ Etiología
Origen multifactorial: predisposición genética, déficit nutricional (hierro, ácido fólico, vitamina B12), estrés o trauma local.
➤ Signos y síntomas
° Úlceras únicas o múltiples, redondeadas, con halo eritematoso y fondo blanquecino.
° Dolor significativo, que dificulta la alimentación.
➤ Diagnóstico
Clínico, basado en la morfología y ausencia de vesículas previas.
➤ Tratamiento

• Hiperplásica: lesiones blancas no desprendibles.

° Ardor, disfagia y alteración del gusto.
➤ Diagnóstico
Clínico y confirmado por citología exfoliativa o cultivo micológico.
➤ Tratamiento
° Adultos: antifúngicos tópicos (nistatina, miconazol) o sistémicos (fluconazol) en casos persistentes.
° Niños: nistatina en suspensión oral.

📊 Cuadro comparativo: Diferencias entre Herpes Labial, Afta y Candidiasis Oral

💬 Discusión
El diagnóstico diferencial es fundamental: el herpes labial se reconoce por sus vesículas y recurrencia; las aftas carecen de vesículas y se presentan como úlceras dolorosas aisladas; la candidiasis se distingue por las placas blancas o eritematosas persistentes. El abordaje terapéutico varía según la etiología, lo que resalta la importancia de la evaluación clínica minuciosa y, en algunos casos, pruebas complementarias.

✍️ Conclusión
Distinguir entre herpes labial, afta y candidiasis oral permite un manejo oportuno y reduce complicaciones. En adultos y niños, el tratamiento debe individualizarse según la causa y el estado general del paciente. La educación en salud bucal y la identificación temprana son clave para el control de estas patologías frecuentes.
