Specific material recommendations for the restoration of root surface caries are difficult because of a lack of data on the clinical performance of restorative materials in these situations. Although silver amalgam has been successfully used to restore carious roots, resin composite, glass ionomer, and resin-modified glass ionomers are also used to restore root surfaces since they are esthetic and bond to tooth structure. Fluoride releasing materials may inhibit recurrent caries in restored surfaces; however, clinical documentation of this phenomenon is sparse. This paper describes the efficacy of restorative materials used to restore root surfaces, the dynamic movement of fluoride into and out of restorative materials, and the role that fluoride releasing materials may play in the inhibition of recurrent caries in vitro and in vivo. In addition, classifications are given for low, medium, and high caries risk patients and material recommendations are made for each category of patient.
由于缺乏修复材料在这些情况下临床性能的数据，因此很难针对根面龋的修复给出具体的材料建议。尽管银汞合金已成功用于修复龋坏的牙根，但树脂复合材料、玻璃离子体和树脂改性玻璃离子体也用于修复根面，因为它们美观且能与牙体组织粘结。释氟材料可能会抑制修复面的继发龋；然而，关于这一现象的临床文献却很少。本文描述了用于修复根面的修复材料的疗效、氟在修复材料内外的动态移动，以及释氟材料在体外和体内抑制继发龋中可能发挥的作用。此外，还对低、中、高龋风险患者进行了分类，并针对每类患者给出了材料建议。
