Antibiotic Use in 2016 by Members of the American Association of Endodontists: Report of a National Survey.

Introduction: This study surveyed the antibiotic prescribing practices of endodontists, and data were compared with previous surveys conducted in 1994 and 1999.

Methods: A 17-question survey was sent via www.surveymonkey.

A survey for endodontists in today's economy: exploring the current state of endodontics as a profession and the relationship between endodontists and their referral base.

Introduction: The purpose of this study was to assess the perceptions, referral trends, and practice patterns of practicing endodontists in the United States and any effect the recent economy may have had on these.

Methods: A 24-question survey was formulated and sent via www.surveymonkey.

Current trends in endodontic treatment by general dental practitioners: report of a United States national survey.

Introduction: In the United States almost 70% of root canal treatment (RCT) is performed by general dentists (GPs), yet little is known about their treatment protocols.

Methods: A paper survey was mailed to 2000 United States GPs with questions about the types of endodontic cases treated, routine treatment protocols, use of newer technologies, and endodontic continuing education (CE).

Results: Completed surveys were returned by 479 respondents (24%).

Comparison of the self-adjusting file with rotary and hand instrumentation in long-oval-shaped root canals.

Introduction: The aim of this study was to compare the root canal debridement ability of the self-adjusting file (SAF) with ProFile rotary (PF) and hand filing (HF) instrumentation in long-oval-shaped canals.

Methods: Extracted human teeth (n = 30) were selected on the basis of a root canal ratio of ≥2.5:1 measured 5 mm from the root apex.

Effects of bone graft materials on the microhardness of mineral trioxide aggregate.

Introduction: Large through-and-through lesions have been reported to heal faster and better when filled with bone graft material at the time of an apicoectomy. It is unknown what effect these have on retrograde filling materials such as white mineral trioxide aggregate (WMTA). In this study, the null hypothesis was tested that the presence of bone graft materials does not affect the microhardness of WMTA.
