Abstract

Objective. The purpose of this study was to determine the composition of the microbial flora present in teeth after the failure of root canal therapyin a North American population. These results were then compared with those of the previous Scandinavian studies. Study design. Fifty-four root-filled teeth with persistent periapical radiolucencies were selected for retreatment. After removal of tile root-filling material, the canals were sampled with paper points, and by reaming of the apical dentin. Both samples were grown under aerobic and strict anaerobicconditions. Then the bacterial growth was analyzed. Results, The microbial flora was mainly of 1 to 2 strains of predominantlygram-positive organisms. Enterococcus faecalis was the most commonly recovered bacterial species. Conclusions. Bacteria were cultivated in 34 of tile 54 teeth examined in the study. E faecalis was identified in 30% of the teeth with a positive culture.
