Abstract

Objectives: To evaluate the effect of SDF/KI pretreatment on microshear bond strength of 3 different types of GIC to radicular dentin. Also to investigate both micromorphological and elemental analysis of restorations-tooth interfaces Materials and methods: For μSBST, a total of 30 mandibular first molars were vertically splitted. The resulted 60 intact single roots were prepared and embedded into acrylic blocks. Then, they were randomly divided into 3 main groups(n=20) according to restorative material. Group A; Conventional GIC (Riva self cure,SDIltd,Australia), group B; CPP-ACP modified GIC ( FujiVII-EP, GC corp., Japan ) and group C; RMGIC (Riva light cure, SDI ltd., Australia).

氟化二胺银/碘化钾阻龋剂对玻璃离子水门汀与根状牙本质结合影响的体外研究
目的:评价SDF/KI预处理对3种不同类型GIC与根状牙本质微剪切结合强度的影响。材料和方法:采用μSBST法垂直分离30颗下颌第一磨牙。结果60根完整的单根被制备并嵌入丙烯酸块中。然后根据修复材料的不同,随机分为3组(n=20)。A组;常规GIC (Riva self cure,SDIltd,Australia), B组;CPP-ACP改性GIC (FujiVII-EP, GC corp, Japan)和C组;RMGIC (Riva light cure, SDI ltd, Australia)。所有60个样品首先用25% PAA (RIVA conditioning SDI ltd, Australia)进行调理。然后,根据SDF/KI的应用(Riva Star,SDIltd,Australia)将每组进一步分为2个亚组(n=10),对照亚组(I)不使用SDF/KI,待测亚组(II)经SDF/KI预处理。然后用直径1.2mm、高度3mm的根管在根表面进行GIC施用。GICs应用后,有60个样品,60个材料微球体粘接在其表面。在μSBST前,将标本保存在蒸馏水中24h。然后分别安装在通用测试机上进行μSBST测试。然后用体视显微镜和扫描电镜分析各脱粘试件的破坏模式。为了进行显微形态学分析,并按照相同的研究设计,在每个亚组的分叉区再增加6颗臼齿进行GIC修复。它们被垂直切片以暴露修复牙的界面。每一半准备一个正常和另一个酸碱挑战技术。所有正常制备的一半首先进行EDX元素分析,然后在使用SEM扫描之前,所有一半都溅射涂上金。采用IBM- spss软件(26.0版,IBM, NY, USA)对μSBS试验数据进行制表、编码和统计分析。多重比较采用单因素方差分析和Tukey事后检验。显著性水平为(p<0.05)。结果:单因素方差分析结果显示,常规GICs和pcp - acp改良GICs的对照亚组与SDF/KI治疗亚组比较,差异均无统计学意义(p > 0.05)。与RMGIC组相反,SDF/KI治疗亚组的μSBS平均值较对照组有统计学意义(p小于0.05)。显微形态学分析表明,使用SDF/KI并对沉淀进行冲洗对GICs对根状牙本质的粘附和适应没有不利影响。在所有SDF/KI处理亚组的gics -根状牙本质界面的EDX分析中检测到微量的银离子。结论:根据目前的研究结果,无论是SDF/KI制剂作为龋病治疗剂,还是GIC作为治疗空化根病的首选材料,都可以获得好处,而不必担心GIC与根状牙本质的结合强度会受到损害,特别是当使用RMGIC时。此外,将SDF/KI应用于洗涤沉淀和温和干燥,有助于保持gic与根状牙本质的结合强度。牙根龋被认为是老年牙科中常见的牙齿问题之一。据报道,这是老年患者牙齿脱落的主要原因之一。每年根龋增加0.47-1。成年人每年表面的流行率为45%,这表明预防成人根龋应成为国家口腔卫生的一个高度优先事项。牙根龋的新问题可以通过再矿化策略、重塑技术和各种已建立的和最近引入的材料的修复来治疗。SDF/KI制剂已被推荐和确认为预防和治疗牙根龋。因此,对于空化根病变的治疗,强烈建议联合应用SDF/KI进行初始再矿化,然后进行手术干预和GIC修复,以增强保守观念和修复的存活率。尽管如此,这一步骤对GICs与根本质表面粘附的影响仍是值得怀疑的。同样,它也可能受到根管解剖和组织学特征的影响。许多研究已经研究了SDF/KI剂对不同类型复合材料和gic仅与冠状牙本质结合的影响。然而,很少甚至没有类似的研究利用被认为是SDF/KI剂的主要作用领域之一的牙本质根。致谢:我对曼苏拉大学牙科学院牙科外科教授hananabd - el Razak Hegazi的支持表示深切的感谢和最深的谢意,我很荣幸能在她慷慨的指导下工作。 我也要对曼苏拉大学牙科学院牙科外科助理教授Hamdi Hosni Hamdan的“氟化二胺银/碘化钾阻龋剂对玻璃离子水门汀与根状牙本质结合的影响:体外研究”表示深切的感谢。曼苏拉牙科杂志2021;8(31):65-66。[6]罗丽娜·马赫参考文献1,李志强,李志强。印度金奈一家医院门诊部成人口腔健康相关生活质量中华口腔卫生杂志2010;2:45-55。[2]王晓明,王晓明,王晓明,等。牙根性龋的防治研究进展。专业护理牙医2013;33:133-140。谢凯。老年人群牙齿和牙周病的感染性并发症。中华临床传染病杂志2002;34:1215-1223。[4]张建军,张建军,张建军,等。氟化二胺银在老年人群中的应用及临床疗效评价。Gerodontology2017; 4:411419。burrow MF, Stacey MA。空化根龋的治疗:最小干预和替代方法。中华口腔医学杂志,2017;26:106-114。[6]张建军,张建军,张建军,张建军。纳米级氟化银对牙釉质粘接强度的影响?[endnoteref: 1] [endnoteref: 7]。[7]小泉纯一郎,滨马HH,布罗MF。一种含氟二胺银和碘化钾的脱敏和龋齿清洗剂对牙本质结合强度的影响。[J] .中国医学工程学报,2016;38(5):559 - 561。knight GM, McIntyre JM, Mulyani。氟化银和碘化钾对自固化玻璃离子水门汀与牙本质结合强度的影响。[J]; 2006;51:42-45。[9]李建军,张建军,张建军,等。氟化二胺银对牙本质粘接强度的影响。Dent Mater 2018;37: 1003 - 1009。[10]张建军,张建军,张建军,等。牙本质预处理后自蚀刻和自蚀刻胶粘剂的微剪切粘接强度及纳米渗漏性能的研究。[J]中华医学杂志,2016;27:42 - 45。
