Bacterial Coronal Leakage after Obturation with Three Root Canal Sealers

Journal of Endodontics, 2001
The purpose of this study was to compare the bacterial leakage of root canals obturated with three root canal sealers, using Endodontalis faecalis as a microbial tracer to determine the length of time for bacteria to penetrate through the obturated root canal to the root apex.

Bacterial Leakage in Implants With Different Implant–Abutment Connections: An In Vitro Study

Journal of Periodontology, 2012
Background: Two‐piece implants present gaps and cavities between the implant and the abutment, and these hollow spaces can act as a trap for bacteria. The aim of the present in vitro study was to evaluate the migration of two different microbial species from the inside to the outside of the implant–abutment assembly in three different connection types ...

Effect of irrigation with Tetraclean on bacterial leakage of obturated root canals.

The New York state dental journal, 2014
The purpose of the study presented here was to evaluate the effect of Tetraclean, Hypoclean, Chlor-XTRA, 2% chlorhexidine and 6% sodium hypochlorite/17% EDTA as a final irrigant on bacterial leakage of the root canal. One hundred and fifty-five extracted human maxillary central incisors were randomly divided into five experimental groups of 25 teeth ...

The role of implant-abutment connection in preventing bacterial leakage: a review.

Journal of biological regulators and homeostatic agents, 2019
Osseointegration can be affected by oral conditions; in particular, the micro gap at the implantabutment-connection (IAC) represents a site for dental plaque aggregation favoring bacterial leakage that can increase inflammatory cells at the level of the IAC, causing peri-implantitis.

Bacterial leakage of provisional restorative materials used in endodontics.

Quintessence international (Berlin, Germany : 1985), 2010
To test the bacterial sealing ability of commonly used provisional endodontic restorative materials.This study investigated Cavit (3M ESPE), Ketac (3M ESPE), DuoTemp (Coltane/Whaledent), and a combination technique using Ketac and Cavit. One hundred molars were randomly selected and then mounted in an apparatus that isolated the crown portion of the ...

Coronal Leakage: Bacterial Penetration through Obturated Canals Following Post Preparation

The Journal of the American Dental Association, 1994
Coronal leakage of bacteria from saliva into root canal filling materials is a potential cause of failure. This problem may be more pronounced when only a small volume of obturating material remains in the canal, such as after post preparation. In this study, coronal leakage of bacteria through unsealed, apically obturated canals was investigated using

Bacterial leakage in root canals filled with AH Plus and dentine bonding agents

Acta Odontologica Scandinavica, 2014
The aim of this study was to compare the efficacy of different dentine adhesives in delaying the coronal bacterial leakage of Enterococcus faecalis in filled root canals. Materials and methods. Ninety-five lower incisors of patients >65 years of age were instrumented using the ProTaper system and were irrigated with 1 mL of 2.5% sodium hypochlorite ...

EndoREZ sealer and Enterococcus Faecalis: a bacterial leakage study

2010
Objective. The purpose of this study was to investigated the coronal bacterial leakage, over a 50-day period, of root canal filling with EndoREZ, a new sealer containing methacrylate, and to compared with a conventional obturation technique, mixed lateral and warm vertical condensation, using zinc oxide and eugenol cement (ZOE) and gutta-percha points.

Bacterial leakage in external hexagon implants with and without the interposition of a sealing-connector.

American journal of dentistry, 2018
To investigate whether the interposition of a sealing-connector was able to reduce the bacterial leakage in external hexagon implants.20 implants with external hexagon connection were used. Ten Test implant-abutment assemblies were connected with the interposition of a sealing-connector molded in the exact shape of the two opposed surfaces. Ten Control

Epidemiology and Characteristics of Bacterial Meningitis of Children with Cerebrospinal Fluid Leakage or Cochlear Implant

Journal of the Pediatric Infectious Diseases Society
Abstract Background Cerebrospinal fluid (CSF) leakage is a recognized risk factor for bacterial meningitis. Few data are published concerning bacterial meningitis in children with CSF leakage, and the impact of 13 valent pneumococcal conjugate vaccination (PCV13) in this population is not well ...
