With the aging of the American population and the endemic problem of gingival recession, patients will inevitably suffer from greater exposure of root surfaces and therefore will be more likely to develop root caries. The treatment of root caries is often frustrating. Traditional biomaterials used for the restoration of enamel caries have been less than satisfactory when margins of a cavity are adjacent to cementum. Although topical fluoride gels, toothpastes, and rinses have been used to prevent or to inhibit the development of root caries, there is a problem of access to the proximal surfaces. Consequently, the development of better methods to facilitate the prevention of root caries has become an important issue in dentistry.
随着美国人口老龄化以及牙龈退缩这一普遍问题的存在，患者将不可避免地面临更大程度的牙根表面暴露，因此更有可能发生根龋。根龋的治疗往往令人沮丧。用于修复牙釉质龋的传统生物材料，当龋洞边缘靠近牙骨质时，效果并不理想。尽管局部用氟凝胶、牙膏和漱口水已被用于预防或抑制根龋的发展，但存在难以触及邻面的问题。因此，开发更好的预防根龋方法已成为牙科领域的一个重要问题。
