ABSTRACT
AIM: To 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). METHODS: This 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™ (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. RESULTS: There 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). CONCLUSION: The application of the GC Tooth Mouse (CPP-ACP) was similar to placebo in increasing the salivary pH and salivary flow rate.
