Background: Children aged 14 years old are susceptible to dental caries, because children at that age, parental influence wanes and they become independent in oral and dental health behavior. The characteristics of saliva, such as pH and salivary flowrate, have significant roles in the process of caries protection. Objective of the Research: To find out the effect of salivary pH and salivary flow rate towards dental caries status of 14 year old students in SMPN 1 Gamping. Research Method: This study was an analytical observational research with cross sectional approach implemented on 58 students of 14 year old in SMPN 1 Gamping. The sampling technique used was simple random sampling. The dental caries status measurement used DMFS index. The salivary pH measurement was conducted by using digital pH meter. The salivary flowrate measurement was conducted by using Mettler Toledo PL303. The statistical analysis used was pearson correlation and multiple linier regression. Research Result: Based on the pearson correlation and multiple linear regression test result, there is a correlation between salivary pH and salivary flow rate towards DMFS index. The correlation between salivary pH and DMFS index gains 0,000 p value, while the correlation between salivary flowrate and DMFS index gains 0,001 p value (p<0,05). The multiple linear regression analysis results in adjusted R2 = 0,361, which means salivary pH and salivary flowrate have correlation with DMFS index as much as 36.1%. Conclusion: The degree of salivary pH and salivary flowrate were positively associated to the dental caries ststus of 14 year old students in SMPN 1 Gamping.
