Abstract

Background: Saliva plays an important role in homeostatic processes in the oral cavity, such as mastication, digestion, protecting the oral mucosa, self-cleansing and remineralization. Long term smoking habits can reduce the flow rate of saliva, this will interfere with self-cleansing in the oral cavity which results a decrease in oral hygiene. Xylitol gum can stimulate the salivary glands so it can increase the flow rate of saliva followed by an increase in oral hygiene. Objective: To determine the ratio of salivary flow rate before and after chewing gum containing xylitol on smokers and non-smokers. Method: This research was a quasi experimental with non equivalent control group design on 20 smokers and 20 non-smokers. Respondents were instructed to chew xylitol gum for 5 minutes. Saliva collection using the spitting method. Measurement of salivary flow rate using digital scales. Result: There is a significant increase salivary flow rate in each group. Independent t-test showed that there was a significant comparative difference (p=0,001) increase salivary flow rate on smokers and non- smokers. The increasing ratio of salivary flow rate on smokers was 0,233 mL/minute and the non- smokers was 0,572 mL/minute. Conclusion: There is a significant difference in the ratio of increased salivary flow rate between smokers and non-smokers. Salivary flow rate on smokers increased a lower rate than non-smokers.
