Remineralization of teeth with casein phosphopeptide-amorphous calcium phosphate: analysis of salivary pH and the rate of salivary flow

AimTo investigate the changes of salivary flow rate and salivary pH of Syrian children with mixed dentition following application of Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP).MethodsThis study is part of a double-blind randomized controlled clinical trial. It included 50 children aged 6-8 who were randomly divided into two treatment groups to receive either CPP-ACP GC Tooth Mousse (TM) (Group A) or placebo (Group B) with 25 participants per group. After the application of the product in the mouth for 3 min, saliva samples were collected four times (T0, T1, T2, and T3) to measure salivary pH and the rate of salivary flow.ResultsThere was no significant difference between group A and B in the mean value of salivary flow rate (t = 1.08, P = 0.28, 0.57 +/- 0.28 versus 0.56 +/- 0.38 respectively) and salivary pH (t = 0.61, P = 0.54, 7.28 +/- 0.44 versus 7.25 +/- 0.36 respectively). However, there was a significant difference between different time points (T0, T1, T2, and T3) in the mean value of salivary flow rate (0.41 +/- 0.30, 0.65 +/- 0.36, 0.53 +/- 0.28, and 0.56 +/- 0.34 respectively) and salivary pH (6.99 +/- 0.44, 7.46 +/- 0.36, 7.36 +/- 0.32, and 7.26 +/- 0.32 respectively).ConclusionThe application of the GC Tooth Mouse (CPP-ACP) was similar to placebo in increasing the salivary pH and salivary flow rate.
