摘要
背景:本研究的目的是评估新型生物活性材料的氟化物和钙的释放,并将结果与表面硬度和牙釉质脱矿阻力联系起来。材料和方法:考虑三种离子释放修复材料:Surefil one (SO)、Equia forte fil HT (EF)和Activa bioactive reative (AB)。记录修复材料的基线显微硬度(MH)。在离水贮存7、14、21 d的不同时间间隔内,测定了材料的氟、钙离子释放量和显微硬度。离子色谱法记录离子释放值。最后用显微硬度计评估牙釉质脱矿阻力。利用扫描电子显微镜和能量色散x射线能谱(SEM\EDX)评估牙釉质表面形态、钙和磷wt. %。结果:SO组氟离子释放量高于其他各组(p< 0.05),钙离子释放量低于其他组(p< 0.05)。与AB相比,EF的氟化物和钙离子释放量更多。在所有时间间隔中,MH值最高的是SO,其次是EF,两种材料在储存后都有显著的MH增加。AB的MH最低,随贮藏而降低。结论:EF是一种有效的修复材料,应用于龋病介质中,保存后具有足够的表面硬度。关键词:生物活性材料,离子释放,牙釉质脱矿阻力,显微硬度
Ion Release, Microhardness and Enamel Demineralization Resistance of New Bioactive Restorative Materials.
Background: The objective of the study was to assess fluoride and calcium release from new bioactive materials and to correlate the results with surface hardness and enamel demineralization resistance.
Material and methods: Three ion releasing restorative materials were considered: Surefil one (SO), Equia forte fil HT (EF), and Activa bioactive resorative (AB). Baseline microhardness (MH) of the restorative materials was recorded. The amount of released fluoride and calcium ions and microhardness of the materials were estimated at different intervals of 7,14 and 21 days storage in distallid water. Ion release values were recorded using Ionchromatography. Finally, enamel demineralization resistance was evaluated using a microhardness tester. Enamel surface morphology, calcium and phosphorous wt. % were evaluated utilizing the scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM\EDX).
Results: SO released more fluoride and lower calcium ions than the other groups (p< 0.05). EF recorded more fluoride and calcium ion release compared to AB. The highest MH values at all intervals were for SO followed by EF, both materials exhibited significant MH increase upon storage. AB exhibited the lowest MH which decreased upon storage. In the acid resistance test, EF showed effective resistance to demineralization followed by AB.
Conclusions: EF is an effective restorative material when applied in cariogenic media with adequate surface hardness qualities upon storage. Key words:Bioactive material, Ion release, Enamel demineralization resistance, Microhardness.
