| Abstract: | Objective:To compare the microbiological status within the root canal of untreated and root-filled teeth with chronic apical periodontitis and to determine the association of the various species with clinical features.Methods:Ninety single root canals with chronic apical periodontitis were examined.Forty-five of them were primary apical periodontitis and the others were persistent apical periodontitis.According to clinical features the specimens were divided into three groups:pain,fistula and symptomless.Th... |
| Keywords: | Chronic apical periodontitis Root canal treatment failure Endodontic infection Clinical feature |
