The increased use of soft drinks leads to a high prevalence of dental erosion (DE), and the use of polymers can decrease tooth demineralization by a carbonated drink. Assessment of the effect of food-approved polymers such as highly esterified pectin (HP), propylene glycol alginate (PGA), and gum arabic (GA) on their efficiency to reduce enamel demineralization on addition with a commercially available carbonated drink was the main objective of this study.
For this study, 300 premolar teeth were studied for enamel erosion and were divided into five groups consisting of 60 samples in each group. The teeth treated with distilled water had negative control, a commercially available carbonated drink with pH 2.7 had positive control, and food polymers were added individually to the carbonated drink in a specified quantity with minimal pH change and were taken as groups A, B, and C, respectively. The enamel erosion that occurred in study groups was measured using a laser fluorescence spectroscopic system with laser excitation at 404 nm at different treatment times (30, 60, and 120 seconds). Results: Demineralization was less in samples treated with polymer added to carbonated drink solutions compared to samples exposed to plain carbonated drink. As the time of exposure increased up to 120 seconds, a significant decrease in demineralization occurred in polymer-treated groups of samples as against plain carbonated drink with HP showing more decreased demineralization with extended exposure periods compared to other polymers. The surface morphology of tooth samples exhibited the anti-erosive effect of polymers, and the scanning electron microscopic pictures revealed a smoother surface for the polymer-added group.
This study shows the efficacy of HP, PGA, and GA on reducing the effect of carbonated drink-induced enamel demineralization, and these polymers' addition to drinks can be an innovative way to reduce the demineralization potential of carbonated acidic drinks.
软饮料的使用增加导致牙齿侵蚀（DE）的高患病率，而聚合物的使用可以减少碳酸饮料引起的牙齿脱矿。本研究的主要目的是评估食品批准的聚合物，如高酯化果胶（HP）、藻酸丙二醇酯（PGA）和阿拉伯胶（GA），在添加市售碳酸饮料时降低牙釉质脱矿的效率。
在本研究中，对300颗前磨牙进行牙齿侵蚀研究，并分为五组，每组60个样本。用蒸馏水处理的牙齿作为阴性对照，pH值为2.7的市售碳酸饮料作为阳性对照，将食品聚合物分别以特定量添加到碳酸饮料中，pH变化最小，并分别作为A、B和C组。在不同处理时间（30、60和120秒）使用激光激发波长为404 nm的激光荧光光谱系统测量研究组中发生的牙釉质侵蚀。结果：与暴露于纯碳酸饮料的样本相比，添加聚合物的碳酸饮料溶液处理的样本脱矿较少。随着暴露时间增加到120秒，与纯碳酸饮料相比，聚合物处理组的样本脱矿显著减少，与其他聚合物相比，HP在延长暴露时间时脱矿减少更多。牙齿样本的表面形态显示了聚合物的抗侵蚀作用，扫描电子显微镜照片显示添加聚合物的组表面更光滑。
本研究表明HP、PGA和GA在降低碳酸饮料引起的牙釉质脱矿方面的功效，将这些聚合物添加到饮料中可能是一种降低碳酸酸性饮料脱矿潜力的创新方法。
