形成膜的聚合物和显著减少软饮料侵蚀. 线性聚酸盐 (LPP) 单独保护了牙和牙,而与乳酸五水合物 (CLP) 的组合提供了增强的保护,特别是牙.
科学领域:
- 牙科材料科学 牙科材料科学
- 口腔健康研究 口腔健康研究
- 生物材料工程是生物材料的工程.
背景情况:
- 牙侵蚀是一个越来越令人担忧的问题,酸性软饮料往往会加剧这种情况.
- 形成膜的聚合物和离子显示出减轻牙侵蚀的潜力.
- 了解改性饮料的保护机制对于预防性牙科至关重要.
研究的目的:
- 评估薄膜形成聚合物 (线性聚酸盐 - LPP,三甲酸盐 - TMP) 和乳酸五水合物 (CLP) 在降低软饮料对牛膜和牙的侵蚀潜力的有效性.
- 评估这些添加剂对防止表面损失的综合作用.
- 分析饮料性质的变化,如颜色和粘度.
主要方法:
- 软饮料配方被修改为LPP和/或TMP,有或没有CLP.
- 牛牙和牙样本经过了侵蚀-重矿化循环协议.
- 使用光学造型测量量量测量了表面损失.
- 测量了改性饮料的颜色和粘度.
主要成果:
- LPP显著减少了牙和牙的侵蚀,分别减少了约53%和41%.
- 将CLP与LPP或TMP结合使用,可以显著降低表面损失:面的97%和牙的56-48%.
- 单独使用CLP也可以减少表面损失,但与聚合物的组合可以提供更好的保护.
- 没有观察到饮料颜色或粘度的显著变化.
结论:
- 含有乳酸 (CLP) 的溶液有效降低了软饮料的侵蚀潜力.
- 添加LPP或TMP与CLP相结合,显著增强了保护作用,特别是对于牙.
- 仅线性聚酸盐 (LPP) 已被证明是有效的,可以最大限度地减少牙和牙的侵蚀.
- 这些发现表明,有可能为那些有侵蚀性牙磨损高风险的人开发保护性饮料.
