Saliva is one of the important factors in maintaining dental and oral health which plays a role in the protective function. The protective function is carried out by increasing salivary secretion which can be measured by flow velocity, volume, pH and viscosity. Objective: The purpose of this study was to determine the comparison of chewing gum containing xylitol and sorbitol to increase salivary pH in students of the Department of Dental Health, Poltekkes, Ministry of Health, Palembang. Methods: This research is a quantitative research with a quasi-experiment method. In taking samples used purposive sampling technique. Research data collection was carried out by measuring the pH of saliva using a pH meter. Results: The results showed that the chewing gum group containing xylitol had an average increase in salivary pH of 1.828, the chewing gum group containing sorbitol had an average increase in salivary pH of 1.632 and the chewing gum group containing a combination of xylitol and sorbtiol had an average increase The pH of saliva is 1.803. Conclusion: It can be seen that the increase in the average salivary pH was the highest in the chewing gum group containing xylitol.
