PERBANDINGAN PH SALIVA SETELAH MENGONSUMSI PERMEN SUKROSA YANG MENGANDUNG EKSTRAK GAMBIR (Uncaria gambir Roxb.) DAN TANPA GAMBIR
Background:Candy is a high-calorie food product, typically made with added sucrose, and if consumed excessively, it can lead to a decrease in saliva pH. A decrease in saliva pH causes the oral cavity to become acidic, facilitating the growth of bacteria, which in turn triggers cavities. To prevent a decrease in saliva pH, gambir extract is added to the candy. Gambir (Uncaria gambir Roxb.) is a herbal plant that contains flavonoid compounds such as catechins and tannins, which have antibacterial properties. This study aims to compare the saliva pH after consuming sucrose candy containing gambir extract and without gambir.Methods: An experimental study with a pretest-posttest with control group design was conducted, consisting of a sucrose candy group with gambir extract and a group without gambir. The research subjects were 32 students from the Part of Dentistry, Sriwijaya University. Saliva samples of 5 ml were collected before and after consuming the candy using the spitting method and measured using a digital pH meter. Paired t-tests and independent t-tests were performed to analyze the data. Results: This study showed that after consuming sucrose candy containing gambir extract, there was a significant increase in the average saliva pH compared to before consuming the candy (p < 0.05). Candy without gambir, after consumption, showed a significant decrease in saliva pH compared to the pH before consumption (p < 0.05). Conclusion:The group that consumed sucrose candies containing gambir extract (Uncaria gambir Roxb.) showed an increase in saliva pH compared to the group that consumed candies without gambir. Key words: gambir, candy, salivary pH, sucrose
