[Haemophilia and dental procedures; a complex combination].

A 28-year-old patient with severe haemophilia A presented to the emergency department with significant and painful swelling of the left cheek, an extensive haematoma extending from the left ear to the anterior thoracic region, an intraoral haematoma over the soft palate with deviation of the uvula to the right, and complaints of shortness of breath when lying down. Three days prior, his dentist had performed a restoration of the 36 molar under local anaesthesia. Due to pain, the general practitioner had administered an intramuscular injection of a non-steroidal anti-inflammatory drug (NSAID) two days post-procedure. The patient was admitted for treatment with coagulation factors and pain management. Dental procedures and local anaesthesia in patients with a severe coagulation disorder require specific preparatory measures, such as administration of coagulation factors. Collaboration and consultation with a patient's haematologist or haemophilia treatment centre are essential requirements for safe dental care.
