In vivo evaluation of root canal sealer distribution
Journal of Endodontics, 1995The 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.

Evaluation of the radiopacity of different root canal sealers
Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2009The aims of this study were to compare the radiopacity of 8 root canal sealers relative to gutta-percha and dentin in standard discs and to evaluate the effect of these sealers on the radiopacity of root canal fillings in simulated canals.Radiographs were taken of 1-mm-thick specimens of 8 root canal sealers (Diaket, Endion, MTA, Endofil, Roeko Seal ...

The Rheology of Selected Root Canal Sealer Cements
Journal of Endodontics, 1978A 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, 2020Root 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, 2009AbstractAim 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, 1991Various 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.

[In vitro evaluation of five root canal sealers].
Minerva stomatologica, 2003An adequate film thickness is an important property of an endodontic sealer, when used in combination with gutta-percha, to eventually fill minimal voids between gutta-percha and the root canal walls, ensuring an hermetic three-dimensional root canal obturation. The goal of the present study was to evaluate the film thickness of the following five root

The effect of temperature on viscosity of root canal sealers
International Endodontic Journal, 2006AbstractAim 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.

Cytotoxicity evaluation of six root canal sealers
Journal of Endodontics, 1995Cell 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 ...

The influence of root canal shape on the sealing ability of two root canal sealers
International Endodontic Journal, 2006AbstractAim To evaluate the influence of root canal form on the sealing ability of two root canal sealers.Methodology Twenty radiographically confirmed straight and 20 curved root canals were prepared with a stepback hand filing technique. Root canal aberrations created during preparation were determined by the use of double exposure radiographic ...
