Fluoride release of two glass-ionomer cements: in vitro study
Objective: The aim of the present study was to compare the amount of fl uoride released by two glass-ionomer cements: Ketac Molar Easymix® (3M ESPE), which has recently appeared in the market and offers the additional advantage of easy mixing, and FUJI II® (GC Dental Industrial Corporation), which h...

Fluoride release of two glass-ionomer cements: in vitro studyDelgado Muñoz, Carol RubíRamírez Ortega, Juana PaulinaYamamoto Nagano, AdolfoGlass ionomer cementfl uoride release.Objective: The aim of the present study was to compare the amount of fl uoride released by two glass-ionomer cements: Ketac Molar Easymix® (3M ESPE), which has recently appeared in the market and offers the additional advantage of easy mixing, and FUJI II® (GC Dental Industrial Corporation), which has been for a longer time available in the market. Methods: Both materials were handled according to the manufacturer’s instructions. 15 samples were made of each glass ionomer cement using sample molds which measured 4 mm diameter x 6 mm height. Glass ionomer cement was placed into the molds and then pressed. Samples were introduced in an oven (37 ± 1 o C at 90% relative humidity). After one hour had elapsed, samples were withdrawn from the oven and then individually immersed in 1 mL de-ionized water in a hermetically sealed plastic container, to be later stored in a chamber at 37 ± 1 o C. After 24 hours, samples were removed from the chamber and withdrawn from the storing solution, they were then rinsed with deionized water and excess water was removed with blotting paper. Samples were then transferred to another container adding 1 mL deionized water in order to be placed in the oven under the same conditions. Total ionic strength adjustment buffer solution was incorporated into the storing solution for it to be read with the help of a potentiometer (pH-meter) and a fluoride selective electrode for fl uoride under magnetic agitation. Prior to conducting fl uoride measurements, solutions were prepared in different concentrations in order to establish the calibration curve. The same procedure was performed in the aforementioned manner during the 36 days which the study lasted. Results: Both cements released fl uoride. For both cements, highest release was observed during the fi rst 24 hours. Release declined during the second day and kept gradually decreasing with time. Results were statistically analyzed using the Mann-Whitney test. No statistically significant differences were observed. Conclusions: Both glass ionomer cements exhibited similar fl uoride release. Glass ionomer cement are ideal for use in preventive dentistry as well as in atraumatic restorative technique.Facultad de Odontología2019-05-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.unam.mx/index.php/rom/article/view/6957710.22201/fo.1870199xp.2014.18.2 ING.69577Revista Odontológica Mexicana; Vol. 18 No. 2 (2014): Versión InglésRevista Odontológica Mexicana Órgano Oficial de la Facultad de Odontología UNAM; Vol. 18 Núm. 2 (2014): Versión Inglés1870-199Xreponame:Revista Odontológica Mexicanainstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMspahttps://revistas.unam.mx/index.php/rom/article/view/69577/61418Derechos de autor 2019 Universidad Nacional Autónoma de Méxicoinfo:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/695772024-08-16T20:10:25Z |
