ICD-10: P35.1

ORPHA: 294

General information

Estimated occurrence
Injuries due to cytomegalovirus infection during the foetal stage are uncommon.
The cytomegalovirus is a virus infection belonging to the herpes group. The virus can be activated by certain circumstances, and following a primary infection, the cytomegalovirus remains latent in the body for life. If a woman is infected by the cytomegalovirus during pregnancy, the infection can, in 50 % of cases, be transferred to the foetus. There is then an increased risk (10 %) of foetal injury (CMV).
General symptoms
A cytomegalovirus infection during the foetal stage can, for example, lead to early birth, low birth weight, failure to thrive, small head circumference, and can affect internal organs, such as the liver or spleen. There is also a risk that foetal injury will result in symptoms like cerebral palsy, epilepsy, visual impairment and hearing loss.

Orofacial/odontological symptoms

CMV doesn’t include any general malocclusions or dental development disruptions. Children who medicate can sometimes experience oral cavity side effects such as dry mouth, fungal infections, increased bleeding tendency, and thickened gums. In cases of neurological injury, oral motor skills and speech development are often affected, and many face sucking, chewing and swallowing difficulties, and have reduced saliva control.

Advice on follow-up and treatment

  • Early contact with dental services for intensified prophylactic care and oral hygiene information is essential.
  • Feeding and swallowing difficulties are investigated and treated by a specialist team at the hospital or multidisciplinary treatment centre.
  • Speech, language and communication training are often required.
  • Training in oral motor skills and extra stimulation in cases of eating disorders, speech difficulties and impaired saliva control may be necessary.
