This study compared green and black tea to soda and orange juice in terms of their erosive effect on the human dentition. Vinegar and water were used as active and passive control fluids. An accelerated in vitro test was used to monitor how short- and long-term exposure to these fluids affected the topography and morphology of the coronal segments of the human dentition. This 20-week test was conducted under controlled conditions, independent of the influencing factors of the oral environment. The erosive effects of these fluids were categorized generally into three groups: highly erosive (vinegar), moderately erosive (soda and orange juice), and minimally erosive (black and green tea). The erosive effect of tea was similar to that of water, which has no erosion potential. Given the systemic and dental benefits of tea and the low potential for erosion, green and black tea should be highly encouraged for daily beverage consumption.
本研究比较了绿茶和红茶与苏打水及橙汁对人类牙列的侵蚀作用。醋和水分别用作活性和非活性对照液。采用加速体外试验来监测短期和长期接触这些液体如何影响人类牙列冠部的形貌和形态。这项为期20周的试验在可控条件下进行，不受口腔环境影响因素的干扰。这些液体的侵蚀作用大致分为三组：高侵蚀性（醋）、中度侵蚀性（苏打水和橙汁）和低侵蚀性（红茶和绿茶）。茶的侵蚀作用与没有侵蚀潜力的水相似。鉴于茶对全身和牙齿的益处以及低侵蚀可能性，应大力鼓励将绿茶和红茶作为日常饮品。
