Introduction:
Graft-versus-host disease (GVHD) is a complication of haematopoietic stem cell transplantation (HSCT). GVHD may also develop following solid transplants or blood transfusions if white blood cells are transferred. GVHD affects multiple organs, including the oral tissues.
Objective:
This pictorial review provides a background of GVHD to dental practitioners, describes the most common oral manifestations of GVHD and highlights the main treatment modifications needed to deliver dental care to patients with GVHD.
Methods:
A narrative review enhanced with clinical photographs.
Results:
Acute GVHD may manifest in the oral mucosa; however, it often develops immediately following HSCT when routine dental treatment is postponed. Chronic GVHD may manifest in the oral mucosa, the salivary glands and the musculoskeletal compartment. It may indirectly affect the teeth and the oral flora, putting the patient at risk for infections. Importantly, GVHD poses an increased risk for oral cancer.
Conclusion:
GVHD has a wide range of oral manifestations, some of which may affect dental treatment.
