Caries clinical trials of sugar-free chewing gum have shown that the gum is noncariogenic and in fact has anticariogenic effect through the stimulation of saliva. Sugar-free gums, therefore, may be an excellent delivery vehicle for safe and effective additive, capable of promoting enamel remineralization. Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) nanocomplexes incorporated into sugar-free chewing gum have shown to remineralize enamel subsurface lesions in situ. So this study was conducted to evaluate the effect of CPP-ACP containing sugar-free chewing gum on salivary concentration of calcium and phosphorous.
Unstimulated saliva from each 24 selected subjects was collected. Then each subject was given two pellets of chewing gum containing CPP-ACP and asked to chew for a period of 20 min, after which saliva samples were collected from each individual. Once all the samples were collected they were assessed for calcium and phosphorous concentration using affiliated reagent kits and photometer.
Data obtained were analyzed using student's paired t test.
Significant difference was found in the calcium and phosphorus concentration of saliva before and after chewing CPP-ACP containing chewing gum.
Chewing of CPP-ACP containing chewing gum showed a significant increase in the salivary concentration of calcium for a prolonged period of time hence it may help in the remineralization of tooth surfaces.
无糖口香糖的龋齿临床试验表明,该口香糖无致龋性,事实上通过刺激唾液还具有防龋作用。因此,无糖口香糖可能是一种安全有效的添加剂的理想载体,能够促进牙釉质再矿化。已证实,添加到无糖口香糖中的酪蛋白磷酸肽 - 无定形磷酸钙(CPP - ACP)纳米复合物可使牙釉质表层下病变原位再矿化。所以开展本研究以评估含CPP - ACP的无糖口香糖对唾液中钙和磷浓度的影响。
收集24名选定受试者的非刺激性唾液。然后给每位受试者两粒含CPP - ACP的口香糖,让其咀嚼20分钟,之后收集每个人的唾液样本。所有样本收集完毕后,使用配套试剂盒和光度计评估钙和磷的浓度。
对获得的数据采用学生配对t检验进行分析。
咀嚼含CPP - ACP的口香糖前后,唾液中钙和磷的浓度存在显著差异。
咀嚼含CPP - ACP的口香糖可使唾液中钙的浓度在较长时间内显著升高,因此可能有助于牙齿表面的再矿化。
