Аннотация
Systemic disorders in pediatric patients, such as congenital biliary atresia, acute liver failure, and biliary hypoplasia, may be the indications for a need of liver transplantation. One of the manifestations of these disorders is the elevated serum levels of bilirubin (hyperbiliru-binemia), a product of hemoglobin degradation, which is deposited in different tissues, including mineralized and soft tissues. When hyperbilirubinemia occurs during the period of dental development, these teeth can develop a green coloration, which remains permanently, because, after maturation, these tissues loose their metabolic activity. This case report describes a 9-year-old girl who required a liver transplant due to biliary atresia when she was three years old. Some of her pigmented teeth needed extraction and afterwards were submitted for histological analysis and compared with sound teeth.
