fa Fluoride and silver concentrations of silver diammine fluoride solutions for dental use کودکان Pediatric Dentistry پژوهشي Research <p> <strong>Objective</strong></p><p>  To determine the short-term stability of free fluoride ion concentrations and acidity (pH values) of three commercially available SDF solutions over time. </p><p> <strong>Methods</strong> </p><p> Three SDF products for caries control were studied: Cariestop-12%, Cariestop-30% and Saforide-38%. Their expected fluoride ion concentrations were 14,200, 35,400 and 44,800 ppm, respectively. The fluoride ion concentrations were determined with an ion-selective electrode. The acidity was determined with a pH electrode. The measurements were performed when open and at 7 and 28 days. </p><p> <strong>Results</strong></p><p>  The mean fluoride ion concentrations of the freshly opened bottles were 12,525 ± 450, 13,200 ± 2060 and 55,800 ± 2536 ppm, respectively. The mean pH values were 9.4 ± 0.1, 10.4 ± 0.1 and 10.2 ± 0.2, respectively. No significant change (P > 0.05) in the fluoride ion concentrations or the acidity was detected after 7 or 28 days. </p><p> <strong>Conclusion</strong></p><p>  The three SDF tested solutions were alkaline. The fluoride ion concentrations of Cariestop-30% and Saforide-38% were considerably different. The fluoride ion concentrations and acidity of the products demonstrated a short-term stability over 28 days. </p><hr><p></p><p> <strong>Source: </strong>International Journal of ‍ Pediatric Dentistry</p><p> <a href="http://onlinelibrary.wiley.com/doi/10.1111/ipd.12005/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-2485&slc_lang=fa&sid=1 Mey Lei Mei 100319475328460011847 100319475328460011847 No Faculty of Dentistry, The University of Hong Kong, Sai Ying Pun, Hong Kong Chun Hung Chu chchu@hku.hk 100319475328460011848 100319475328460011848 Yes Faculty of Dentistry, The University of Hong Kong, Sai Ying Pun, Hong Kong Edward Chin Man Lo 100319475328460011849 100319475328460011849 No Faculty of Dentistry, The University of Hong Kong, Sai Ying Pun, Hong Kong Lakshman Perera Samaranayake 100319475328460011850 100319475328460011850 No Faculty of Dentistry, The University of Hong Kong, Sai Ying Pun, Hong Kong
