Dental erosion is defined as the loss of tooth structure due to chemical process that does not involve bacteria. The management of such a condition calls for a comprehensive approach to identifying the cause and treating it.
The aim of this study is to comparatively evaluate the role of grape seed extract (GSE) and cranberry extract (CE) in preventing dental erosion using optical emission spectrometry.
Prepared enamel specimens were subjected to the erosive challenge using HCl for 10 s, followed by immersion in experimental natural groups and control fluoride group for 30 s and artificial saliva for 60 min. This cycle was repeated three times. The amounts of calcium and phosphorous present in the acid solution after 1, 2, and 3 erosive challenges were determined for each group using induced coupled plasma-optical emission spectrometry.
The cumulative calcium and phosphorous release after the 1, 2, and 3 erosive challenges were found to be the least in SnF2 group, followed by GSE group and then in CE group.
The protective of GSE and CE was inferior to the gold standard control group of stannous fluoride role, against enamel erosion. GSE showed better remineralizing effect; however, there was no statistically significant difference between the two groups.
牙侵蚀被定义为由于不涉及细菌的化学过程导致的牙体结构丧失。这种情况的处理需要一种全面的方法来确定病因并进行治疗。
本研究的目的是使用光发射光谱法比较评估葡萄籽提取物（GSE）和蔓越莓提取物（CE）在预防牙侵蚀中的作用。
制备的牙釉质标本用盐酸进行10秒的侵蚀挑战，然后在实验天然组和对照氟化物组中浸泡30秒，再在人工唾液中浸泡60分钟。这个循环重复三次。使用电感耦合等离子体光发射光谱法测定每组在1、2和3次侵蚀挑战后酸溶液中钙和磷的含量。
发现在1、2和3次侵蚀挑战后，氟化亚锡组的钙和磷累积释放量最少，其次是GSE组，然后是CE组。
在预防牙釉质侵蚀方面，GSE和CE的保护作用不如氟化亚锡这一金标准对照组。GSE显示出更好的再矿化效果；然而，两组之间没有统计学上的显著差异。
