In vitro evaluation of fluoride release of Jeltrate dental alginate

Objective: To evaluate of fluoride release from Jeltrate alginate . Materials and Methods: Four Trademarks of alginate were divided in four groups: conventional Jeltrate , Plus Jeltrate , Chromatic Jeltrate and Chromatic Ortho Jeltrate . The alginates were handled following the guidelines of the manufacturers. After this was followed by the construction of evidence bodies using silicone molds of the dimensions of 4 mm in diameter and 4mm in height. After take prey, the evidence bodies were removed from the molds and placed in container with 10 ml of ultra purified water, for 2 min. The fluoride release was measured by selective ion electrode connected to an analyzer of ions. Results: The Plus Jeltrate showed a higher releasing fluoride 247.85 μg/cm2) followed by Chromatic Ortho Jeltrate (217.83 μg/cm2), Chromatic Jeltrate (138.21 μg/cm2) and Jeltrate (79.61 μg/cm2). Conclusion: Plus Jeltrate had the best performance in releasing fluoride, followed by Chromatic Ortho Jeltrate , Chromatic Jeltrate and conventional Jeltrate .
