| endodontic bacteria from primary and persistent endodontic lesions in chinese patients as identified by cloning and 16s ribosomal dna gene sequencing. | few literatures pertain to the 16s ribosomal dna (16s rdna) analysis of bacteria contributing to primary and persistent endodontic lesions, with no information available for the chinese population. as such, we investigated endodontic bacteria associated with primary and persistent endodontic lesions in adult chinese patients living in beijing, china using 16s rdna gene sequencing techniques. | 2013 | 23422180 |
