Eighteen different infants' drinks from five manufacturers were examined for their carbohydrate, calcium, phosphorus and acid contents, and their attack on tooth mineral. Seven of the drinks were compared with nine varieties of adults' soft drinks, and demineralization was studied with and without the presence of a cariogenic oral streptococcus. The influence of the acids already in the drinks in dissolving Ca and P outstripped that of any acid generated in these studies in vitro by microbial fermentation of the sugars they contained, giving an indication of their relative erosiveness rather than their cariogenic action. Various other features of the drinks relevant to dental health were identified. Titratable acid was a better guide than pH to their dental properties. Although there were considerable differences between the various infants' drinks, taken as a group, their acidity levels and demineralizing powers were generally lower than those of the adults' drinks.
对来自五家制造商的18种不同婴儿饮品进行了碳水化合物、钙、磷和酸含量以及对牙齿矿物质侵蚀性的检测。将其中7种饮品与9种成人软饮料进行了比较，并研究了在有和没有致龋口腔链球菌存在的情况下的脱矿情况。饮品中已有的酸溶解钙和磷的影响超过了这些研究中通过微生物发酵所含糖分在体外产生的任何酸的影响，这表明了它们相对的侵蚀性而非致龋作用。还确定了与牙齿健康相关的饮品的各种其他特征。可滴定酸比pH值更能反映它们的牙齿特性。尽管各种婴儿饮品之间存在相当大的差异，但总体而言，它们的酸度水平和脱矿能力通常低于成人饮品。
