A comparative evaluation of sealing ability of a new, self-etching, dual-curable sealer: Hybrid Root SEAL (MetaSEAL)

An Alternative Adhesive Strategy to Optimize Bonding to Root Dentin

“…In this situation, HRS may provide a more impermeable seal. Sealing performance by this material has been justified (31,35).…”

Contemporary Methacrylate Resin–based Root Canal Sealers Exhibit Different Degrees of Ex Vivo Cytotoxicity When Cured in Their Self-cured Mode

“…Recently, self-adhesive (ie, self-etching) versions of these sealers have been introduced that eliminate the use of a separate priming step (16,17), rendering them easier and faster to use. Although resin composites may show acceptable biocompatibility when polymerized under optimal light-curing conditions (18,19), the cytotoxicity of dualcurable resin-based sealer composites should be evaluated in the self-cured mode (20,21) because this is how the sealers polymerize in the apical third of canal walls and within the periradicular tissues (22).…”

Sealing properties of one-step root-filling fibre post-obturators vs. two-step delayed fibre post-placement

“…The one-step InnoEndo procedure somewhat resembles the single-cone root-filling technique 2,29 in that more than half of the canal space is filled by the sealer. It has been reported that low root-filling material/sealer ratios may not guarantee a longterm hermetic seal of the root canals, since many sealers tend to dissolve over time.…”
