Dental caries remains a significant oral health concern, particularly in young children. With an increasing interest in preventive strategies, pediatric and preventive dentistry research is now more focused on developing newer materials and techniques to coat the primary teeth to prevent the onset of new carious lesions. While traditional preventive measures such as fluoride application and sealants have been effective in reducing caries incidence, there is still a need for innovative approaches.
To evaluate the effectiveness of surface prereacted glass ionomer (S-PRG) light-cured varnish in inhibiting demineralization of primary teeth enamel.
In this study, primary teeth samples were randomly divided into two groups: the control group received no coating, while the test group received an S-PRG filler coat. The samples were allowed to demineralize, and various analyses, including Fourier transform infrared (FTIR) spectroscopy, scanning electron microscope (SEM), energy-dispersive X-ray analysis (EDX), and Vickers microhardness analysis, were conducted. Additionally, biofilms of and were developed on solid surfaces such as microtiter plates, glass, and dentures, and the quantity of bacterial biofilm was measured using crystal violet assay and fluorescence microscopy.
The study results showed that the primary teeth samples in both groups had a significantly greater calcium content than the controls. The S-PRG group demonstrated a significant reduction in the development of biofilms of and as well as bacterial attachment to glass and denture surfaces compared to the control group, as indicated by crystal violet assay and fluorescence microscopy.
The findings of this study suggest that S-PRG filler-containing coating materials have the potential to prevent demineralization and inhibit and biofilm formation on primary tooth enamel.
These results are promising and may have implications for the prevention of dental caries in young children.

龋齿仍然是一个重大的口腔健康问题,尤其是在幼儿中。随着对预防策略的兴趣日益增加,儿童牙科和预防牙科研究现在更加专注于开发更新的材料和技术来覆盖乳牙,以防止新的龋损发生。虽然传统的预防措施如使用氟化物和窝沟封闭剂在降低龋齿发病率方面已经有效,但仍然需要创新方法。
评估表面预反应玻璃离子(S-PRG)光固化清漆对乳牙牙釉质脱矿的抑制效果。
在本研究中,乳牙样本被随机分为两组:对照组不进行涂层处理,而试验组接受S-PRG填料涂层。让样本进行脱矿,并进行各种分析,包括傅里叶变换红外(FTIR)光谱分析、扫描电子显微镜(SEM)、能量色散X射线分析(EDX)和维氏显微硬度分析。此外,在微量滴定板、玻璃和假牙等固体表面形成变形链球菌和远缘链球菌的生物膜,并使用结晶紫测定法和荧光显微镜测量细菌生物膜的数量。
研究结果表明,两组的乳牙样本钙含量均显著高于对照组。结晶紫测定法和荧光显微镜显示,与对照组相比,S-PRG组变形链球菌和远缘链球菌生物膜的形成以及细菌在玻璃和假牙表面的附着显著减少。
本研究结果表明,含S-PRG填料的涂层材料有潜力预防乳牙牙釉质脱矿并抑制变形链球菌和远缘链球菌生物膜形成。
这些结果很有前景,可能对幼儿龋齿的预防有重要意义。
