Bacterial Leakage Versus Dye Leakage in Obturated Root Canals

International Endodontic Journal, 1999
Aim The aim of this study was to compare in vitro bacterial and dye leakage tests, commonly used to determine the seal of root canal fillings.Methodology Ninety‐six single‐rooted teeth had their crowns removed at the cemento‐enamel junction and their roots instrumented to ISO size 60 within 1 mm of the apex.

Bacterial Leakage Along the Implant–Abutment Interface of Premachined or Cast Components

International Journal of Oral and Maxillofacial Surgery, 2008
In recent clinical studies, contamination of the inner parts of dental implants through bacterial penetration along the implant components has been observed. The aim of the present in-vitro study was to investigate leakage of Fusobacterium nucleatum through the interface between implants and premachined or cast abutments.

Influence of Repeated Screw Tightening on Bacterial Leakage Along the Implant–Abutment Interface

Clinical Oral Implants Research, 2009
AbstractObjectives: Bacterial penetration along the implant–abutment interface as a consequence of abutment screw loosening has been reported in a number of recent studies. The aim of this in vitro study was to investigate the influence of repeated tightening of the abutment screw on leakage of Streptococcus mutans along the interface between implants

Development of an anaerobic bacterial leakage model

Journal of Endodontics, 1998
The majority of bacteria associated with infections of endodontic origin are strict anaerobes. The purpose of this study was to develop an endodontic microleakage model using strict anaerobic bacteria in a two-chamber system. Nine species of anaerobic bacteria were tested for viability and detection by either turbidity or color change of the broth.
