摘    要:目的:证实多乐氟能预防碳酸饮料对乳牙牙釉质的脱矿作用。方法:将72个乳牙釉质块随机分成4组,每组18块。人工唾液为对照组(A);可乐碳酸饮料浸泡组(B);多乐氟处理后可乐浸泡组(C);氟化泡沫处理后可乐浸泡组(D)。A组试件不作处理,B组试件浸泡于可乐中30 min,取出后用去离子水冲洗干净放置约4 min,再次浸泡于可乐中30 min,如此循环直至12 h。实验C、D组釉质块分别浸在多乐氟、氟化泡沫涂抹4 min后,后续处理同B组。上述处理后试件分别用扫描电镜、能谱分析仪检测釉质表面的形态变化及Ca2+、P3+含量( 重量百分比)。结果:对A组相比,可乐浸泡可致乳牙釉质表面脱矿;氟化物处理后可降低釉质表面的脱矿程度,并使晶体颗粒体积变大,其表面Ga2+、P3+含量的降低程度也低于B组,差异有统计学意义(P<0.05)。结论:多乐氟可抑制乳牙釉质在碳酸饮料中的脱矿,效果较好,并能促进其再矿化。

Abstract:Objective: To confirm the Duraphat can prevent carbonated drinks caused deciduous enamel demineralization. Methods: 72 tooth enamel blocks were randomly divided into four groups, each group of 18 block. Artificial saliva as control group (A); Cola carbonated drinks immersion group (B); Duraphat treatment after Cola immersion group (C); fluoride foam treated Cola immersion group (D). A, enamel blocks were not treated, B, group of enamel blocks were soaked in carbonated drinks in 30min, after removing the deionized water rinse after placing about 4 min, once again immersed in carbonated drinks in 30, so the cycle until 12 h. In experiment C, D, group of enamel blocks were respectively diped smear 4min dollar fluoride, fluoride foam, subsequent treatment with B group. The treated enamel specimens were determined by scanning electron microscopy, energy spectrum analyzer to detect the enamel surface morphology and Ga, P content (weight percentage). Results: Compared to control group, carbonated beverage soaking can cause the enamel surface demineralization, Ca, P content decreased significantly, and microhardness decreased; Fluoride varnish treatment can reduce the degree of ore removal after the enamel surface, and the crystal particle volume increase, reduce the degree of the surface of the Ca, P content is lower than the A group, the difference has statistical significance(P<0.05). Conclusion: Duraphat can be inhibited to some extent in enamel of deciduous teeth in carbonated beverage, and can promote the remineralization.
Keywords:Primary teeth enamel   Fluor protector   Carbonated drinks
