Abstract

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.
