ISO 9917-2:1998
Dental water-based cements -- Part 2: Light-activated cementsstandard by International Organization for Standardization, 07/01/1998
In stock
This part of ISO 9917 specifies requirements for dental cements, including hand-mixed, encapsulated cements used for mechanical mixing and one-component materials, which are intended for base, lining and restoration purposes and for which the materials are water-based and set by multiple reactions which include an acid-base reaction and polymerization.
EXAMPLE Conventional glass polyalkenoate cements are normally formed by reacting an ion-leachable aluminosilicate glass with a polyalkenoic acid in an aqueous environment. Materials which fall within the scope of this part of ISO 9917 will normally be able to effect setting by such an aqueous acid-base type reaction, but in addition will be able to effect rapid setting through exposure to a suitable source of radiation.
