Green Teeth in the Primary and Permanent Dentition

A 9-year-old girl was admitted to the oral pathology department presenting green teeth coloration. The patient's medical history noted that after 20 days of birth she was diagnosed with biliary atresia. She underwent surgery to restore the bile flow (hepatoportoenterostomy); however, she had persistent conjugated hyperbilirubinemia. At 3 years of age, she underwent liver transplantation and progressed to a thrombosis of the portal vein and splenomegaly. Medications at presentation included tacrolimus as immunosuppressive agent to prevent organ transplant rejection and prednisone.
