[Research on aseptic condition of root canals after endodontic treatment].
Fifty infected root canals were examined whether they had been in aseptic condition or not after endodontic treatment. PLADIA was used for the examination of bacteriologic culture. Twenty eight cases were positive, 22 cases were negative, and the percentage of positive was 56%. Of the anterior teeth, 13 cases were positive in 23 cases (57%), In the posterior teeth, 15 cases were positive in 27 cases (56%), 5 cases were positive in 17 cases (29%) with clinical symptoms before treatment, 23 cases were positive in 33 cases (70%) without clinical symptoms before treatment. These results showed that the treated root canals which had been well adapted to root canal filling by clinical symptoms had a high percentage of positive of bacteriological culture.
