Background: The main factors that cause dental caries are the host (teeth and saliva), substrate (food), microorganisms, time. Saliva as a factor plays role in protective mechanisms. Several changes salivary pH to include average flow rate, oral buffer capacity, frequently consumed foods beverages; One of them is milk. Objective: To investigate differences before after drinking packed cow’s milk children aged 6-12 years old. Methods: Quasi-experimental research methods were conducted using Pretest Posttest Control Group Designs. instruments this study used meter. Statistical Test Student t-Test. Results: There no difference saliva 0 minutes cow's packaged brand A B (p= 0.772 p=0.384, respectively). an 5 (p=0.001). results analysis between liquid with there was significant reducing (p = 0.001). Conclusion: years.
