Erratum

In the Discussion section of the article “Antibiotic Resistance in Primary and Persistent Endodontic Infections” (J Endod 2011;37[10]:1337–44), references were made to work previously performed by Rossi-Fedele et al (references 23 and 24 in the article). The authors wish to correct the language used to refer to that work in the following manner. The statement, “TetM has been identified in tetracycline-resistance Enterococcus faecalis found in endodontic infections (23, 24)” should be “TetM has been identified in tetracycline-resistance bacteria found in endodontic infections (23, 24).” Also, the statement, “These studies found that 8 of 15 tetracycline-resistance bacteria isolated possessed the tetM gene and were resistant to tetracycline irrigation in an in vitro tooth model” should be “These studies found that tetracycline-resistance bacteria were resistant to tetracycline irrigation in an in vitro tooth model.” The authors regret any confusion in describing the work done in these studies.
