Enterococcus spp. isolated from root canals with persistent chronic apical periodontitis in a Chilean population

Abstract Aim: To isolate and identify in a Chilean population,Enterococcus spp. from root canals with persistent chronic apical periodontitis (CAP) and to investigate the potential correlation between the bacteria and the observed clinical features. Methods: Twenty patients with indication for endodontic retreatment due to persistent CAP were selected. Data from patient general health and dental clinical history were recorded. During retreatment, a microbial sample was obtained from the root canal and inoculated in a selectiveEnterococcus medium. Using bacterial cultivation methods, bacteria...
