Trimetaphosphate (TMP) effects on demineralized bovine enamel were studied after 15 days of pH cycling. Treatments included 30 wt% (weight percent) dilutions of 0, 500, 1,500 or 3,000 μg F/g aqueous NaF solutions with or without 3% TMP. Treated specimens were assessed by transverse microradiography. With the exception of the 3,000 μg F/g case, 3% TMP addition provided significant additional overall remineralization compared with F alone. Mineral content profiles differed significantly between corresponding F and F + TMP groups. Fluoride alone resulted in more remineralization in the original demineralized zone, whereas F + TMP caused less demineralization in the underlying, originally sound enamel.
三磷酸五钠(TMP)对脱矿牛牙釉质的影响在 pH 循环 15 天后进行了研究。处理包括 0、500、1500 或 3000μg F/g 水溶液中 30wt%(重量百分比)的稀释浓度,以及含有或不含有 3% TMP 的 NaF 溶液。用横向显微放射摄影术评估处理后的标本。除了 3000μg F/g 情况外,与单独使用 F 相比,添加 3% TMP 可显著提供额外的整体再矿化作用。相应的 F 和 F+TMP 组之间的矿物质含量分布有显著差异。单独使用氟化物会在原始脱矿区域内导致更多的再矿化,而 F+TMP 会导致下方原始健康牙釉质内的脱矿化程度降低。
