Bacteria of asymptomatic periradicular endodontic lesions identified by DNA-DNA hybridization.

Endodontics & dental traumatology, 2000
Possible inclusion of contaminant bacteria during surgery has been problematic in studies of periradicular lesions of endodontic origin. Therefore, in this study, two different surgical techniques were compared. A second problem is that some difficult to
