Profile: Nordiska Dental AB develops, manufactures and markets dental materials with packaging and accessories. Our product calasept® has a very high content of calcium hydroxide (> 41%) giving a high concentration of hydroxyl ions. These generate the high pH value of 12.4 which has a pronounced bactericidal effect, by killing bacteria. High concentration of calcium hydroxide means long-lasting because the paste can release calcium ions for a long time. It is a ready-to-use paste in air tight syringes for direct application through the sterilized needle. Our ANA etching gel is an enamel and dentine etchant with 37% phosphoric acid. It is a well established fact that etching materials should contain 35-40% phosphoric acid. ANA Etching Gel stays in place without collapsing. The viscosity in combination with the blue colour enables very precise and clearly detectable placement. The thin bended needles allow accurate application.
