“…Another study showed no difference between the bond strength values of AH Plus and MTA Fillapex (28). Thus, considering MTA Fillapex, a paste-topaste sealer, two chemical reactions have been identified as being responsible for the setting and physical-mechanical properties of this material: the progressive hydration of orthosilicate ions occurs followed by a reaction between MTA and salicylate resin (21,27).…”

“…Sagsen et al (28) assessed the push-out bond strength of MTA Fillapex and iRoot SP sealer and found no significant differences between iRoot SP and AH-plus (an epoxy resin-based root canal sealer regarded as the (29). The resin components of MTA Fillapex might adversely affect its bonding to dentin and sealing properties (30). Using scanning electron microscopy, Barges et al (31) found that exposing MTA Fillapex specimens to deionized water results in porosities and cracks in the resin matrix.…”

We compared the apical seals of two new calcium silicate-based sealers (iRoot SP and MTA Fillapex) in the presence and absence of a smear layer. Eighty-two human premolars were prepared and randomly divided into four groups. In groups 1 and 3, the smear layer was retained. In groups 2 and 4, the root canals were irrigated with EDTA to remove the smear layer. Canals were filled using gutta-percha/iRoot SP (in groups 1 and 2) or obturated with gutta-percha/MTA Fillapex (in groups 3 and 4). Fluid filtration was used to evaluate apical microleakage. The presence of the smear layer had no significant effect on the sealing properties of the filling materials, except for iRoot SP at 2 weeks (P = 0.007). There was significantly less microleakage with iRoot SP than with MTA Fillapex (P = 0.025 at 2 weeks; P < 0.001 at 3 months). Leakage decreased significantly over time in all specimens, except in group 2 (P = 0.473). In conclusion, removal of the smear layer had no adverse effect on the sealing properties of calcium silicate-based sealers. In addition, the sealing ability of iRoot SP was superior to that of MTA Fillapex. (J Oral Sci 56, 215-219, 2014)

“…28 Another study which compared the MTA Fillapex and AH Plus, utilizing the lateral condensation technique for the obturation procedures, observed similar dentin adhesion among the MTA Fillapex and AH Plus, but lower than Endo-CPM. 29 MTA Fillapex is promising endodontic cement. Its physicochemical properties are similar to Sealapex's.…”

Aim: This study investigated the flowability, setting time, pH, calcium release and bond strength of a MTA-based cement (MTA Fillapex ® ) compared to AH Plus and Sealapex. Materials and methods:For the flowability test, the ISO 6876:2001 specification was utilized and for the setting time test, the ASTM C266-03 specification was utilized. For the pH and calcium release measurements, 10 samples were prepared for each group and analyzed for several different periods. For the push-out test, dentin disks were distributed into three groups, according to the cement utilized and into three subgroups, according to the root third (n = 10). After obturation, the specimens underwent push-out testing. The data were compared statistically using a significance level of 5%. Results:The flowability of all materials was found to be similar (p > 0.05). The setting times were different among the groups tested (MTA Fillapex < Sealapex < AH Plus) (p < 0.05). At days 7 and 28, the MTA Fillapex presented the higher pH values (p < 0.05). At 24 hours and at 14 days, the calcium release of the MTA Fillapex was similar to that of Sealapex (p > 0.05). AH Plus presented the lowest pH and calcium release values (p < 0.05). In all root thirds, the adhesion to the dentin of the MTA Fillapex and Sealapex were significantly lower than that of AH Plus (p < 0.05). Conclusion:MTA Fillapex and Sealapex presented several similar properties and both were found to be different than AH Plus.Clinical significance: This study evaluated the physicochemical and mechanical properties of new MTA-based root canal cement, in order to use this scaler in root canal fillings. MTA Fillapex showed satisfactory properties for clinical use.
