In phase 1, the cumulative fluoride release rate from samples of the resin cements (Panavia F 2.0, RelyX Unicem, MaxCem, and BisCem) was quantified after 15 days storage in water (n=4). In phase 2, the fluoride release profiles from the same materials were analyzed during pH cycling (n=4). In this second phase, fluoride was measured at specific times (one, two, three, five, eight, and 15 days). Disk-shaped specimens were prepared (10 mm × 0.5 mm), and the materials were either light activated or allowed to autopolymerize. For both phases, the fluoride release was measured using a fluoride ion-specific electrode. The fluoride release in water was not affected by the curing mode of RelyX Unicem and Maxcem resin cements. Panavia F. 2.0 and BisCem resin cements, either light cured or autopolymerized modes, released higher amounts of fluoride in water than the other self-adhesive cements. In phase 2, the concentration of fluoride released decreased from the first day of pH cycling until the 15th day for all resin cements, for both curing modes, regardless of the storage solution used (demineralizing/remineralizing). The fluoride release rate during pH cycling by Panavia F 2.0 and MaxCem was not affected by the curing mode. The effect of the curing mode on fluoride ion release in water or during pH cycling was product dependent.</p><hr><p></p><p> <strong> Source: </strong>Operative dentistry </p><p><a href="http://www.jopdentonline.org/doi/abs/10.2341/10-328-L" target="_blank"><font color="#0000cc">  Full text </font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-241&slc_lang=en&sid=1 Thaiane Rodrigues Aguiar 1003194753284600959 1003194753284600959 No Piracicaba School of Dentistry, University of Campinas, Piracicaba, Brazil Cristiane Franco Pinto 1003194753284600960 1003194753284600960 No São Francisco School of Dentistry, São Francisco University, Bragança Paulista, Brazil Vanessa Cavalli 1003194753284600961 1003194753284600961 No Department of Dentistry, University of Taubaté, Taubaté, São Paulo, Brazil Marinês Nobre-dos-Santos 1003194753284600962 1003194753284600962 No Piracicaba School of Dentistry, State University of Campinas, Piracicaba, São Paulo, Brazil Glaucia Maria Bovi Ambrosano 1003194753284600963 1003194753284600963 No Piracicaba School of Dentistry, State University of Campinas, Piracicaba, SP, Brazil Paula Mathias 1003194753284600964 1003194753284600964 No Federal University of Bahia, Salvador, Bahia, Brazil Marcelo Giannini giannini@fop.unicamp.br 1003194753284600965 1003194753284600965 Yes Piracicaba School of Dentistry, University of Campinas, Piracicaba, Brazil
