Microbial shift of oral biofilm associated with remineralization of root dentin lesions.

Purpose: To examine the relationship between remineralization of incipient root dentin lesions and the presence of polymicrobial biofilms, as well as examine changes in microbial composition.

Methods: Bovine root dentin disks used as specimens for biofilm formation, were cultured using saliva from a single donor. Amsterdam Active Attachment biofilm model was used to grow biofilms.
