Adhesion of a Glass–Ionomer Root Canal Sealer to the Root Canal Wall

Journal of Endodontics, 2001
Glass-ionomer root canal sealer is commonly used because of its chemical bonding and favorable physical characteristics when bonding to dentin. This study was designed to determine the tensile bond strength of a glass-ionomer sealer (Ketac Endo, Espe, Seefeld, Germany) on root canal walls after pretreatment with different conditioners.

Glass Ionomer Root Canal Sealers

Journal of Veterinary Dentistry, 1993
Since their introduction, glassionomer cements have undergone changes in formulations and have been endorsed for a number of clinical applications. Consistent reporting of bio-compatibility, durable adhesion, and beneficial fluoride release have followed the evolving glass ionomer cement.

In vivo evaluation of root canal sealer distribution

Journal of Endodontics, 1995
The effectiveness of sealer placement and its distribution in the prepared root canal system by an energized ultrasonic file was evaluated in vivo. One hundred patients had sealer placed into prepared root canals with either the master gutta-percha cone or an ultrasonic file.

The Rheology of Selected Root Canal Sealer Cements

Journal of Endodontics, 1978
A study of the rheological changes of selected root canal sealer cements by indirect capillary extrusion viscometry is presented. Viscosity was measured as a function of shear rate and as a function of elapsed time after mixing the root canal sealer cements.

Genotoxicity of root canal sealers: a literature review

Clinical Oral Investigations, 2020
Root canal sealers are widely used worldwide in endodontics to prevent reinfection and growth of surviving microorganisms. Considering the strong correlation between genetic damage and carcinogenesis, evaluation of genotoxicity induced by endodontic sealers is recommended for elucidating the true health risks to patients and professionals.

Sealing properties of a new root canal sealer

International Endodontic Journal, 2009
AbstractAim  To evaluate bacterial leakage of Apexit Plus, a new root canal sealer, in comparison with AH Plus.Methodology  A total of 56 single‐rooted human teeth were randomly divided into two experimental groups of 16 roots and two control groups. Roots were filled by lateral condensation with Gutta‐percha and AH Plus or with Gutta‐percha and Apexit

A new glass ionomer root canal sealer

Journal of Endodontics, 1991
Various physical characteristics of a new glass ionomer root canal sealer were tested. These included setting time, ease of delivery to the root canal, adaptability and adhesion to the dentinal wall of the root canal, and radiopacity. Scanning electron micrographs and electron microprobe analyses were made.

The effect of temperature on viscosity of root canal sealers

International Endodontic Journal, 2006
AbstractAim  To test the hypothesis that there was no significant (α = 0.05) change in viscosity of commercially available root canal sealers with increase in temperature using a high‐performance Advanced Rheometric Expansion System (ARES) rheometer.Methodology  Materials tested were Apexit, Tubliseal EWT, Grossman's, AH Plus and Ketac‐endo.

Radiopacity of a new root canal sealer, epiphany

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2007
The purpose of this study was to evaluate the radiopacity of a new root canal sealer, Epiphany, relative to 3 other root canal sealing materials, AH 26, Sealapex, and Ketac-Endo.Radiographs were taken of 1-mm-thick specimens of 4 root canal sealers and dentine slides, as well as a range of aluminum thicknesses, by using a step-wedge.

Cytotoxicity evaluation of six root canal sealers

Journal of Endodontics, 1995
Cell cultures of human gingival fibroblasts obtained from healthy patients were used to evaluate the toxicity of six different endodontic cements: AH-26, Pulp Canal Sealer, Rocanal-R2, Rocanal-R3, Bioseal, and Endomethasone. The toxicity was determined by measuring spectrophotometrically at 405 nm the colorimetric reaction of N-acetyl-beta ...
