■比较这两种牙膏的再矿化潜力的文献有限,Elsenz™,其中含有氟钙(Ca)磷硅酸盐,和Shy-NM™,含有Ca磷硅酸钠,是一些再矿化剂。
为了评估和比较Elsenz™和Shy-NM™牙粉对恒牙人工诱发龋齿损伤的再矿化潜力,在采用pH循环模型对口腔环境进行实验室刺激后,使用维氏显微硬度测量方法和扫描电子显微镜(SEM)进行能量色散X射线分析。
■对于这两个参数,将总共30颗健全的人类前磨牙分为六组。I-Elsenz™组洁牙剂,II组-Shy-NM™牙膏,和第三组对照。对试样的表面显微硬度(SMH)进行评估,然后用具有能量色散分析的扫描电子显微镜(SEM-EDAX)进行评估。样本在基线测试,去矿化,和再矿化。对收集的数据进行统计分析。
■用Elsenz™再矿化后的表面显微硬度为359维氏硬度值(VHN),Shy-NM™为312VHN。与Shy-NM™相比,Elsenz™显示出显著更高的再矿化(p=0.002)。再矿化后牙齿标本的SEM-EDAX显示,与去矿质值相比,Ca重量百分比(wt%)增加,对于Elsenz™(45.95±3.55%)和Shy-NM™(47.24±1.99%)均具有统计学意义,随着磷重量%的增加,与Shy-NM™(19.95±0.59%)相比,Elsenz™(20.25±0.95%)具有统计学显著性。
■在本研究范围内,与Shy-NM™洁齿剂相比,Elsenz™生物活性玻璃(BAG)中氟化物的掺入有可能使牙釉质更好地再矿化.它可以,因此,得出的结论是Elsenz™,与Shy-NM™相比,将有效抑制脱矿质。

UNASSIGNED: There is limited literature comparing the remineralization potential of these two dentifrices, Elsenz™, which contains fluoro calcium (Ca) phosphosilicate, and Shy-NM™, which contains Ca sodium phosphosilicate, are a few of the remineralizing agents.
UNASSIGNED: To assess and compare the remineralization potential of Elsenz™ and Shy-NM™ dentifrices on artificially induced carious lesions on permanent teeth, using the Vickers microhardness measuring method and scanning electron microscope (SEM) connected to energy dispersive X-ray analysis after laboratory stimulation of the oral environment employing the pH cycling model.
UNASSIGNED: A total of 30 sound human premolar teeth were divided into six groups for both parameters. Group I-Elsenz™ dentifrice, group II-Shy-NM™ dentifrice, and group III-control. The surface microhardness (SMH) of the test specimens was evaluated followed by a scanning electron microscope with energy dispersive analysis (SEM-EDAX). The specimens were tested at baseline, demineralization, and remineralization. The collected data were subjected to statistical analysis.
UNASSIGNED: Surface microhardness following remineralization with Elsenz™ was 359 Vickers hardness number (VHN), and with Shy-NM™ was 312 VHN. Elsenz™ showed significantly higher remineralization compared to Shy-NM™ (p = 0.002). The SEM-EDAX of the tooth specimens after remineralization revealed an increase in the Ca weight percentage (wt%) compared with demineralization values, which was statistically significant for both Elsenz™ (45.95 ± 3.55%) and Shy-NM™ (47.24 ± 1.99%), along with an increase in the phosphorus wt%, which was statistically significant for Elsenz™ (20.25 ± 0.95%) compared to Shy-NM™ (19.95 ± 0.59%).
UNASSIGNED: Within the scope of this study, the incorporation of fluoride in bioactive glass (BAG) in Elsenz™ had the potential to remineralize enamel better than Shy-NM™ dentifrice. It can, therefore, be concluded that Elsenz™, when compared with Shy-NM™, would be effective in inhibiting demineralization.
