  • 02First dental attendance

§Clinical examination

§Differential diagnosis

Primary herpetic gingivostomatitisFever, gingivitis, vesicles on keratinised and non-keratinised mucosa
Hand, foot and mouth diseaseOral ulcers with palmar and plantar lesions, no marked gingivitis
HerpanginaPosterior oropharyngeal vesicles only
Acute necrotising ulcerative gingivitisPunched-out papillae, halitosis, rare in this age group

§Final diagnosis

Primary herpetic gingivostomatitis (HSV-1)

Generalised acute marginal gingivitis is the key feature that separates primary herpetic gingivostomatitis from herpangina and hand-foot-and-mouth disease, which spare the gingiva. Vesicles on both keratinised and non-keratinised mucosa with fever complete the picture.

§Investigations

  • 01Clinical diagnosis; viral PCR swab only if atypical or immunocompromised
  • 02Assessment of hydration status and urine output

§Treatment plan

  • 01Supportive care is the mainstay: fluids, paracetamol, soft cold diet
  • 02Chlorhexidine swabbing where brushing is impossible
  • 03Aciclovir within 72 hours of onset in severe cases or immunocompromise
  • 04Admission if the child cannot maintain hydration

§Follow-up & outcome

  • 01Oral intake improved by day 5; lesions healed by day 12
  • 02Parents warned about recurrent herpes labialis and autoinoculation to eyes and fingers

§Clinical pearls / learning points

  • 01Do not diagnose 'teething' in a febrile child with widespread oral ulceration.
  • 02Herpetic whitlow and ocular inoculation are real risks — gloves and hand hygiene matter.
  • 03Dehydration, not the ulcers, is what admits these children.
