Ocena in vitro właściwości materiałowych Biodentine w porównaniu z ProRoot MTA
Discussion
Solubility in distilled water
The solubility tests performed in the present study followed the methodology of ISO 6876:2001 [16] because Biodentine and ProRoot MTA can be used as root-end filling materials and thereby getting in direct contact with periapical tissue like sealers.
However, while weight loss of the test specimens was recorded by determining the decline in mass of the material samples after storage in water, as already described by some authors [28-31], the International Standard suggests that the increase in weight of the dish in which the samples have been placed (residue method) should be ascertained as the amount of material removed from the specimens [16, 32, 33]. The specimens were weighed in order to avoid an underestimation of the material going into solution. In order to enhance the accuracy of the measurements, one sample was used for just one immersion period, thus undesirable weight loss of the cements due to repeated drying and immersion was excluded.
It has to be kept in mind that with regard to the strict definition of the physicochemical term solubility, the test used in the present study measured the elution of water-soluble material, but not the solubility. Solubility of a solid is the situation where a pure chemical compound is in thermodynamic equilibrium with its solution [34]. Moreover, it has to [...]
