The British Standards Institutions's document (1974) recommending toothpaste specifications states that 'There is no evidence that any toothpaste ever produces a level of abrasion causing harm to dental enamel'. This paper questions the assumption that the enamel crown, especially at the cervical margin, is able to cope with modern dietary insult and a 'good' oral hygiene regimen, regardless of the enamel abrasivity of the dentifrice used. Once the enamel crown is breached the underlying dentine is sensitive and vulnerable to physical damage. In this work the potential rates of erosive and abrasive loss are related to the thickness of the protective enamel and to the relevance of fluoride treatments for adults. It is suggested that improvements in dental care and an increased tooth life expectancy now make the loss of tooth tissues at the cervical margin more important than is apparent at first sight.
英国标准协会1974年推荐牙膏规格的文件指出：“没有证据表明任何牙膏曾产生过对牙釉质造成损害的磨损程度”。本文质疑这样一种假设，即无论使用的牙膏对牙釉质的磨损性如何，牙釉质冠，尤其是在颈部边缘，都能够应对现代饮食侵害和“良好”的口腔卫生习惯。一旦牙釉质冠被破坏，其下方的牙本质就会敏感且易受物理损伤。在这项研究中，侵蚀性和磨蚀性损失的潜在速率与保护性牙釉质的厚度以及成人氟化物治疗的相关性有关。有人认为，牙科护理的改善和牙齿预期寿命的增加，使得颈部边缘牙齿组织的丧失比乍一看更为重要。
