Ocena in vitro właściwości materiałowych Biodentine w porównaniu z ProRoot MTA
An in vitro study of different material properties of Biodentine compared to ProRoot MTA
Mineral Trioxide Aggregate (MTA; Pro Root MTA, Dentsply Tulsa Dental, Tulsa, OK, USA) is a cement which contains different oxide compounds (sodium- and potassium oxides, calcium oxide, silicon oxide, ferric oxide, aluminium oxide and magnesium oxide) and was introduced in dentistry by Torabinejad and White in the mid-1990s. MTA can be denoted as calcium silicate cement, because its composition is similar to a refined Portland cement, which is available in most hardware stores, mixed with bismuth for radioopacity (Table 1) [1, 2].
In order to set, it must first be mixed with water. If set MTA gets in contact with tissue fluids, its calcium oxide converts into calcium hydroxide (Ca(OH)2). The Ca(OH)2, molecule dissociates into calcium and hydroxyl ions, thereby increasing the pH value to approximately 12.5 and resulting in the release of calcium ions [3-5]. MTA can be used as endodontic reparation cement for root-end fillings, apical plug formation, closure of radicular perforations and for direct pulp capping according to the manufacturer’s product information (Dentsply Tulsa Dental, Tulsa, OK, USA). Since its introduction into the market, the material was examined in several studies and is meanwhile well accepted and [...]
