The erosion caused in vitro by cola-type and guaraná-type beverages (the latter is a soft drink sold in Brazil), and a canned lemon juice on the enamel of human deciduous teeth was analyzed. Morphological analysis of affected enamel was done using stereomicroscopy and scanning electron microscopy (SEM). The harmful effect of all test products on deciduous enamel was clearly demonstrated. Stereomicroscopy showed loss of gloss and an alteration in normal color of enamel, with irregular loss of dental tissue in variable degrees. Such a loss became more serious as the time of incubation increased. Different degrees of solubilization of enamel prisms were demonstrated by SEM, affecting initially the sheaths and the heads of prisms and later their tails. Areas of erosion increased in proportion to the time of incubation. All the products showed a great erosive potential on human deciduous dental enamel.
分析了可乐型和瓜拉那种饮料（后者是一种在巴西销售的软饮料）以及罐装柠檬汁在体外对人乳牙牙釉质造成的侵蚀。使用体视显微镜和扫描电子显微镜（SEM）对受影响的牙釉质进行形态学分析。所有测试产品对乳牙牙釉质的有害影响都得到了明确证明。体视显微镜显示牙釉质失去光泽且正常颜色发生改变，伴有不同程度的牙体组织不规则缺失。随着孵育时间的增加，这种缺失变得更加严重。扫描电子显微镜显示牙釉质棱柱不同程度的溶解，最初影响棱柱的鞘和头部，随后影响其尾部。侵蚀面积与孵育时间成正比增加。所有产品对人乳牙牙釉质都显示出很大的侵蚀潜力。
