“…IRM has a good tissue response when it comes to bone healing similar to mineral trioxide aggregate, MTA. MTA also revealed the ability of hard tissue growth on material surface [20]. This difference could have affected the present study outcome, if MTA would have been used as the retrograde filling material.…”

“…Furthermore, eugenol leaching from IRM and Super-EBA is also known to affect the surrounding periapical tissue by eliciting a minor inflammatory response. This reaction has been discussed in a study by Wälivaara et al [20], where different retrograde filling materials have been used without bone grafting. Also, healing may be influenced by the chewing forces, which may cause a slight displacement of the short, apectomized roots.…”

“…It can be speculated that MTA would improve healing due to its favourable tissue response (Walivaara et al . ) and sealing properties over time (Torabinejad & Parirokh ), especially when the depth of the retrograde preparation of the canal is limited.…”

MTA has been currently commercialized in two different forms, the gray (GMTA) and the white version (WMTA). In particular, the white MTA was developed due to the potential discoloration promoted by the gray version of the cement. The chemical composition of the MTAs is very similar to that of Portland cement despite the addition of components containing bismuth in the MTA's cements [ 91 , 128 ], which aims to confer radiopacity to the materials [ 34 ]. The mixture of the MTA powder with distilled water results in the formation of by-products, such as calcium hydroxide and calcium silicate hydrate gel [ 27 , 28 ] as discussed in Chap. 2 . The particular mechanism of hydration and the structure of the set material result in particular properties displayed by the set MTA.The initial pH of the MTA is approximately 10.2, but it increases to 12.5 after 3 h immersed in solution [ 177 ]. MTA has the ability to sustain high values of pH during long periods [ 75 ]. The high pH values exhibited by MTA are attributed to the constant release of calcium and the formation of calcium hydroxide.Several studies had reported release of calcium from MTA [ 12 , 74 , 131 ]. The calcium ion release is enhanced when calcium chloride is added as an accelerator to MTA [ 12 ]. Moreover, when MTA was placed into the root canals of teeth with simulated radicular resorption, a greater calcium ion release was detected in comparison to teeth not fi lled with MTA [ 131 ]. Setting TimeThe hydration of the MTA powder produces a colloidal gel, which solidifi es and results in a solid structure. MTA is prepared by mixing the powder with distilled water using a ratio of 3:1 (powder/distilled water) [ 184 ].
