Evaluation of glass ionomer as an endodontic sealant: An in vitro study

Cytotoxic Effects of Four Different Endodontic Materials in Human Periodontal Ligament Fibroblasts

“…We have also shown that MTA had no cytotoxic effect on PDL fibroblasts. Glass-ionomer-based sealers have varying degrees of cytotoxic effect (8,19). In this study, the results for Endion and Diaket with regard to cytotoxicity with MTT assay and cell viability with trypan blue were similar to previous findings (9, 20) (ie, glass ionomer-based cements were harmful to the cultured cells).…”

Resistance to Fracture of Roots Obturated with Novel Canal-filling Systems

“…This could be attributed to the chemical bond developed between the ceramic particles found in both sealers and those in the ActiV GP cones as previously reported (9,11,14). On the other hand, neither a chemical nor a physical bonding could have been created between any of the sealers tested and conventional GP cones (25). The combined effect of the chemical and mechanical bonding of the iRoot SP sealer to dentin wall as well as the chemical bonding between the sealer and ActiV GP core material might have resulted in a significantly increased fracture resistance comparable to that of uninstrumented roots.…”

Clinical applications of glass ionomers in endodontics: a review

“…Malone and Donnelly evaluated coronal microleakage in obturated root canals using two different sealers [Super‐EBA (Harry Bosworth Co., Skokie, IL, USA), Ketac‐Endo] without coronal restorations and found that neither sealer allowed bacterial penetration through the apical foramen during the 60‐day test period. Lee et al . investigated the sealing ability of GI as a root canal sealer with and without lateral condensation of gutta‐percha cones.…”
