Pengaruh Berkumur Obat Kumur Propolis dalam Meningkatkan pH Saliva Rongga Mulut pada Anak Usia 7-9 Tahun di SD PAB 12 Sampali

Abstract

Potential of hydrogen (pH) is a measure used to measure the acidity of a solution. Normal salivary pH ranges from 6.8 to 7.8, and low pH ranges from 5.2 to 5.5. Salivary pH is often used as an indicator of caries assessment due to its effectiveness in preventing caries. This study aims to determine the effect of gargling with propolis mouthwash (Pieras Propolinse Sakura) on increasing salivary pH. This study was an experimental study with a pre-test and post-test control group design. The sampling technique was purposive sampling. The sample in this study were 40 children aged 7-9 years old, divided into two groups of 20 each. The treatment group gargled with propolis mouthwash, while the negative control group gargled with distilled water. Saliva was collected before and after treatment into a saliva pot for 5 minutes using the spitting method. Saliva pH was measured using a Hanna pH meter. Data analysis was performed using the Wilcoxon test. The results of the study showed that the average pH of respondents' saliva before gargling with propolis mouthwash was 6.39 ± 0.52, while the average pH of respondents' saliva after gargling with propolis mouthwash was 7.07 ± 0.46. The results of the statistical test showed a significant difference in increase between salivary pH before and after gargling with propolis mouthwash (p = 0.000). The results of the Mann-Whitney statistical test showed no significant difference in salivary pH before gargling (p = 0.732) and after gargling (p = 0.133) with propolis mouthwash between men and women. The results of the Kruskal-Wallis statistical test showed no significant difference in salivary pH before gargling (p = 0.659) and after gargling (p = 0.943) with propolis mouthwash between the ages of 7, 8, and 9 years.
