The present invention is directed to the use of a compound of Formula (II) or a salt thereof, wherein x = 1-3; R2 is H, OH, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, or -A-(N(R4)-C(O)-C(R3)=CH2)x; each R3 is independently H or CH3; each R4 is independently H, or an alkyl group; and A is (CH2)n, wherein n = 1 to 20; to prepare a composition for treatment of tooth surfaces that are not pretreated with phosphoric acid.
本发明涉及式(II)化合物或其盐的用途,其中x=1-3;R2是H、OH、烷基、芳基、烷氧基、芳氧基或-A-(N(R4)-C(O)-C(R3)=CH2)x;每个 R3 独立地是 H 或 CH3;每个 R4 独立地是 H 或烷基;以及 A 是 (CH2)n,其中 n = 1 至 20;以制备一种用于处理未用磷酸预处理的牙齿表面的组合物。
