目的 评价6种牙齿充填修复材料的释氟和再充氟性能,以期为临床选择和应用提供参考.方法 选择材料A(FujiⅦ玻璃离子水门汀)、材料B(FujiⅡLC光固化玻璃离子水门汀)、材料C(Beautifil离子体复合树脂)、材料D(Compoglass F复合体)、材料E(Charisma普通复合树脂)及材料F(实验Ⅰ型释氟性复合树脂)作为实验材料,制备直径10 mm、厚1 mm的圆片,每组10个试样.每个试样浸于5 ml去离子水中,用氟离子选择电极测定浸出液氟离子量,浸泡1～7d每天测定,8～28d3d测定1次,计算每日释氟量.于浸泡28 d后用氟化泡沫对试样充氟4min,继续测定试样每日释氟量,连续测定7d;再充氟并测定氟释放7d,重复3次.结果 浸泡1d后所有材料均表现最大的释氟量,材料A释氟量最大[(99.68±15.21) μg·cm-2·d-1],其次为材料B[(37.12±1.67) μg·cm-2·d-1],再次为材料F和D[分别为(22.93±1.53)和(15.28±0.70) μg·cm-2·d-1],材料C和E释氟量较小[分别为(2.40±0.52)和(0.11±0.02) μg·cm-2· d-1],各组间差异有统计学意义(P＜0.05).浸泡2d后释氟量显著下降,随后(7～ 28 d)释氟量下降缓慢;浸泡1～28 d内,材料A和B的释氟量始终大于其他材料(P＜0.01),其次是材料D和F,显著大于材料C和E(P＜0.01).所有材料充氟1d后的释氟量均较充氟前显著增加,形成释氟高峰,充氟2d后的释氟量又显著下降.充氟1d后材料A的释氟量超过40 μg· cm-2·d-1,大于其他材料(P＜0.01);其次是材料B,释氟量超过25 μg· cm-2·d-1,大于除A外的其他材料(P＜0.01);材料C、D、F释氟量相近,在15～ 20μg·cm-2·d-1之间;材料E释氟量较小,＜1.5 μg· cm-2·d-1.结论 玻璃离子水门汀类材料的释放及再充氟能力最强,其次是复合体和释氟性复合树脂,离子体复合树脂释氟能力小,但其再充氟能力与复合体和释氟性复合树脂相当,普通复合树脂的释氟及再充氟能力均较小.

Objective To evaluate the F-releasing and recharging properties of six dental restorative materials.Methods Disc specimens 10 mm in diameter and 1 mm in thickness were prepared from 6 different dental restorative materials:Fuji Ⅶ [glass ionomer cement(GIC)],Fuji lⅡ LC(light-curing,GIC),Beautifil(giomer),Compoglass F(compomer),Charisma(composite) and Experimental Ⅰ (a fluoride releasing composite),with 10 discs for each material.Specimens were dipped in 5 ml deionized water and Frelease was detected using a fluoride-specific ion electrode every day from 1-7 days and every three days from 8-28 days.On day 28,specimens were exposed to a fluoride foam for 4 min and then dipped in water,then the F-concentration was detected every day for a week.The specimens were exposed to fluoride foam and fluoride release was detected repeatedly for three times.Results All materials presented the highest F release on the first day after dipping and the F-release sharply decreased after 24 h and slowly decreased after 3 days.On the first day,Fuji Ⅶ presented the highest F-release[(99.68± 15.21) μg· cm-2· d-1],followed by Fuji Ⅱ LC[(37.12±1.67) μg·cm-2·d-1],Experimental Ⅰ [(22.93±1.53) μg·cm-2·d-1],Compoglass F[(15.28±0.70) μg· cm-2· d-1],Beautifil[(2.40±0.52) μg· cm-2· d-1] and Charisma[(0.11±0.02) μg· cm-2· d-1].Within 28 days of dipping,both Fuji Ⅶ and Fuji Ⅱ LC released more F-than other materials did(P＜0.05),followed by Compoglass F and Experimental Ⅰ,and Beautifil and Charisma released the least F-(P＜0.01).After Fuptake,all materials released the highest F-on the first day and presented sharply decrease after 24 h and slowly decrease after 2 days.On the first day after F-uptake,Fuji Ⅶ presented the highest F-release (＞40 μg· cm-2· d-1),much more than other materials(P＜0.01),followed by Fuji Ⅱ LC(＞25 μ.g· cm-2· d-1).Beautifil,Compoglass F and Experimental Ⅰ were close in F-release value(15-20 μg·cm-2· d-1),and Charisma showed the lowest F-release.Conclusions Two glass ionomers were shown to have highest capacity in F-release and uptake,followed by compomer and fluoride releasing composite.Composite demonstrated the lowest F-release and uptake and Giomer was comparable to composite in F-release and to compomer and fluoride releasing composite in F-uptake.
