“…It has been shown that the implantation of barium sulfate in the subcutaneous connective tissue of the rat elicits a granulomatous tissue reaction (Cabrini et al, unpublished data). Smith et al (22) speculate that barium ions are not biocompatible, since they found severe foreign-body reactions in contact with this material. On the other hand, Meryon & Jakeman (23) have demonstrated that various levels of zinc concentration are extremely toxic for fibroblast and macrophage cell cultures.…”

Silicone tubes containing a freshly mixed experimental Sealapex, in which titanium dioxide was removed from the original formula, were implanted in the dorsal subcutaneous connective tissue of the rat. Solid silicone rods of the same size as the tubes were also implanted and used as inert controls. The tissue reaction to both these materials was histometrically and quantitatively studied under light microscopy and by elemental electron microprobe analysis. After 7, 30 and 90 d of implantation, different grades of tissue reaction to the tested materials were recorded. A granulomatous tissue containing numerous foreign-body giant cells and macrophages with engulfed particles in their cytoplasms was initially detected in contact with the test material. In addition, many fibroblasts and newly formed vessels were also observed at these areas. The results of this study revealed that these reactions increased progressively at the 30- and 90-d observations. The electron microprobe analysis of the granulomatous tissues showed the presence of heavy components of the experimental material.

REVIEW ARTICLE: Calcium hydroxide has been used in endodontology for many years. The aim of this paper is to review the various formulations of calcium hydroxide that have been described, with specific reference to the vehicle used to carry the compound. The requirements for a vehicle are described, and ex vivo and in vivo studies reviewed. Vehicles can be classified into aqueous, viscous and oily, the clinical properties of calcium hydroxide changing depending on the vehicle. The review also describes the use of various active components that have been added to calcium hydroxide, including antimicrobial and anti-inflammatory agents. This review will help clinicians to make informed judgements about which formulations of calcium hydroxide should be used for specific endodontic procedures.

“…Cathers et al 126) have reported barium sulfate to be nondegradable, with possibly toxic effects. Smith et al 127) found that barium ions are not biocompatible, and severe foreign body reactions occurred in tissues contacting this material. Up to 20% barium sulfate mixed with Portland cement showed poor radiopacity, thus greater amounts of radiopaque agent should be added to meet the ISO recommendations.…”

Calcium silicate-based cements have superior sealing ability, bioactivity, and marginal adaptation, which make them suitable for different dental treatment applications. However, they exhibit some drawbacks such as long setting time and poor handling characteristics. To overcome these limitations calcium silicates are engineered with various constituents to improve specific characteristics of the base material, and are the focus of this review. An electronic search of the PubMed, MEDLINE, and EMBASE via OVID databases using appropriate terms and keywords related to the use, application, and properties of calcium silicate-based cements was conducted. Two independent reviewers obtained and analyzed the full texts of the selected articles. Although the effects of various constituents and additives to the base Portland cement-like materials have been investigated, there is no one particular ingredient that stands out as being most important. Applying nanotechnology and new synthesis methods for powders most positively affected the cement properties.
