The Effect of Rubber Dam Usage on the Survival Rate of Teeth Receiving Initial Root Canal Treatment: A Nationwide Population-based Study

Outcomes of Primary Endodontic Therapy Provided by Endodontic Specialists Compared with Other Providers

“…Final restoration and use of dental dam isolation have also been shown to have a significant impact on the long-term outcomes of endodontic treatment, but these factors cannot be adequately derived from claims data. 5,17,18,24 Despite the limitations of this study, the high long-term survival rates of endodontically treated teeth reconfirm the predictability of endodontic treatment provided by the dental health system as a whole. One-year, 5-year, and 10-year survival rates of 96%, 92%, and 86%, respectively, represent survival rates similar to those of previous studies.…”

“…These include but are not limited to the absence of an apical lesion, use of dental dams during treatment and core placement, use of surgical operating microscopes, periodontal condition, structural integrity/restorability of the tooth, biofilms, and effective post-endodontic restoration. 4,14,15,16,17,18,19,20,21,22 The endodontic literature is replete with research focused on these local factors, yet few articles have been published that focus on the effect of provider training on outcomes. Alley et al 23 found that endodontic treatment provided by endodontic specialists was more than 10% more successful than treatment provided by general dentists.…”

Correlation between Enterococcus faecalis and Persistent Intraradicular Infection Compared with Primary Intraradicular Infection: A Systematic Review

“…It is the most common enterococcal species found in the oral cavity occasionally (24), and patients with periodontitis appear to harbor more E. faecalis than their counterparts with a healthy periodontium (26,28,29). Therefore, the oral cavity might be the origin of E. faecalis entering root canal systems, and the use of a rubber dam to insure good isolation is necessary to prevent the introduction of E. faecalis during endodontic treatment (30). Proper periodontal treatment or tooth cleaning before root canal therapy in order to control periodontal inflammation may reduce the amount of E. faecalis.…”

General Dentists' Use of Isolation Techniques during Root Canal Treatment: From the National Dental Practice-based Research Network

“…(1) A recent population-based study found that the survival probability of initial RCT after 3.43 years is significantly greater when a RD was used, although the magnitude of the difference was only about 2% (90.3% with RD, 88.8% without RD). (3) Literature from the past five decades reveals that RD use during RCTs varies by year of publication and country in which the study was conducted. (4–18) Of studies conducted in the United States, the prevalence of always using a RD was about 7% in 1967, 62% in 1989, 58% in 2008 and 60% in 2014.…”
