Measurement of hepatitis B virus DNA in fresh versus processed dentin from chronically infected patients

open access: yesJournal of Translational Medicine, 2018
Background Demineralized dentin matrix (DDM) is commonly used as a bone-graft substitute. This study measured and compared human hepatitis B viruses (HBV) DNA in fresh dentin to that of dentin processed into DDM extracted during dental treatment from HBV-
