Fluoride release and recharge in giomer, compomer and resin composite
Objectives. The aim of this study was to examine the fluoride recharging and releasing abilities of resin-based materials containing fluoridated glass filler to determine whether the extent of the glass–ionomer matrix of the material affects these properties.

| description | Objectives. The aim of this study was to examine the fluoride recharging and releasing abilities of resin-based materials containing fluoridated glass filler to determine whether the extent of the glass–ionomer matrix of the material affects these properties.
Methods. Three materials having a different proportion of the hydrogel matrix surrounding the glass filler, namely: Reactmer paste, Dyract AP and Xeno CF, were used for this study. Five disk specimens of each material were placed into distilled/deionized water and the fluoride release measured during 38 days. For fluoride recharge the disks were exposed to 250 ppm F solution for 1 h and the pre- and post-recharge fluoride release were determined using an ion-selective electrode (total fluoride ions) and ion chromatography (free fluoride ions).
Results. The amounts of total and free fluoride release from each material at the initial period in descending order were Reactmer paste>Dyract AP>Xeno CF (

Results. The amounts of total and free fluoride release from each material at the initial period in descending order were Reactmer paste>Dyract AP>Xeno CF (
p<0.05, ANOVA and Scheffe's test). After fluoride recharge, Reactmer paste showed a greater amount of fluoride release than the other materials. Dyract AP and Xeno CF showed a similar total level of fluoride release after recharging. For Xeno CF the amount of total fluoride released after recharging was significantly greater than that of free fluoride, but there was no significant difference between total and free fluoride released after recharging for Dyract AP (
p=0.05, paired
t-test).
Significance. These results suggested that the extent of the glass–ionomer matrix of the glass filler played an important role for fluoride-releasing and recharging abilities of the resin-based materials.</description><identifier>ISSN: 0109-5641</identifier><identifier>EISSN: 1879-0097</identifier><identifier>DOI: 10.1016/j.dental.2003.11.009</identifier><identifier>PMID: 15451233</identifier><language>eng</language><publisher>England: Elsevier Ltd</publisher><subject>Analysis of Variance ; Cariostatic Agents - chemistry ; Chromatography, Ion Exchange ; Compomer ; Compomers - chemistry ; Composite Resins - chemistry ; Dentistry ; Fluoride release ; Fluorides - chemistry ; Giomer ; Glass Ionomer Cements - chemistry ; Materials Testing ; Recharge ; Resin composite</subject><ispartof>Dental materials, 2004-11, Vol.20 (9), p.789-795</ispartof><rights>2004 Academy of Dental Materials</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c517t-ebc5ab3e66cf7c1b0d5d2669cdda3b5850118f80aa2f8467fa54cc726ca360f93</citedby><cites>FETCH-LOGICAL-c517t-ebc5ab3e66cf7c1b0d5d2669cdda3b5850118f80aa2f8467fa54cc726ca360f93</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://www.sciencedirect.com/science/article/pii/S0109564103002148$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,776,780,3537,27901,27902,65306</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/15451233$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Itota, Toshiyuki</creatorcontrib><creatorcontrib>Carrick, Thomas E.</creatorcontrib><creatorcontrib>Yoshiyama, Masahiro</creatorcontrib><creatorcontrib>McCabe, John F.</creatorcontrib><title>Fluoride release and recharge in giomer, compomer and resin composite</title><title>Dental materials</title><addtitle>Dent Mater</addtitle><description>Objectives.
