■当致病菌突破釉质层时,会出现白斑病变。可以使用复杂的方法治疗白斑病变(WSL)。最关键的步骤是停止去矿化和生物膜形成,并使用各种策略来再矿化病变,变薄,微磨损,侵蚀入渗,粘合剂复合树脂修复体,和粘合面。
■为了评估和比较氟化物,钙,和磷离子释放,再矿化功效,和两性离子材料的显微硬度,自组装肽,和生物活性玻璃(BGA)与MI清漆。
■最初的研究是在60颗提取的前磨牙上进行的;计算的样本量为每组10颗。所有样本分为四组-A组,MI清漆(对照),B组,MI清漆+两性离子材料,C组,MI清漆+自组装肽,D组,MI清漆+BGA。所有这些组进一步评估和比较氟化物,钙,和phorphus离子释放,再矿化功效,和表面显微硬度(SMH)。
■两性离子材料,当掺入MI清漆时,在偏振光显微镜(PLM)下显示出高氟化物和钙离子释放和高再矿化功效。BGA,当与MI清漆掺入时,在SMH的评估中显示出高磷离子释放和更高的值,其次是两性离子材料和自组装肽。
■MI清漆单独具有WSL的再矿化性能,但是当两性离子等新型材料时,自组装肽,和BGA合并,其功效增加。在所有两性离子离子中,氟离子和钙离子的释放和再矿化以及BGA对磷离子的释放和SMH显示出优异的结果。

UNASSIGNED: White spot lesions occur when the pathogenic bacteria have broken through the enamel layer. White spot lesions (WSLs) can be treated using a complex approach. The most crucial step is to stop demineralization and biofilm formation and use assorted strategies for remineralization of lesions, thinning, microabrasion, erosion infiltration, adhesive composite resin restorations, and the bonded facets.
UNASSIGNED: To evaluate and compare the fluoride, calcium, and phosphorus ion release, remineralizing efficacy, and microhardness of zwitterionic material, self-assembling peptide, and bioactive glass (BGA) incorporated with MI Varnish.
UNASSIGNED: The original study was conducted on 60 extracted premolars; the sample size calculated was 10 per group. All samples were divided into four groups-group A, MI Varnish (control), group B, MI Varnish + zwitterionic material, group C, MI Varnish + self-assembling peptide, and group D, MI Varnish + BGA. All these groups were further evaluated and compared for fluoride, calcium, and phorphorus ion release, remineralizing efficacy, and surface microhardness (SMH).
UNASSIGNED: Zwitterionic material, when incorporated with MI Varnish showed high fluoride and calcium ion release and high remineralizing efficacy under polarized light microscopy (PLM). BGA, when incorporated with MI Varnish showed high phosphorus ion release and higher values in the evaluation of SMH, followed by zwitterionic material and self-assembling peptide.
UNASSIGNED: MI varnish alone had remineralizing properties of WSLs, but when novel materials like zwitterionic ion, self-assembling peptide, and BGA are incorporated, its efficacy increases. Among all zwitterionic ions showed superior results for fluoride and calcium ion release and remineralization and BGA for phosphorus ion release and SMH.
