Abstract
Background: The acidic environment due to the interaction of bacteria in the oral cavity triggers the occurrence of dental caries. It is characterized by the increased of bacterial activity at critical pH (4.5-5.5). Mouthwash is used as an antibacterial, but it has unwanted side effects. Herbal mouthwash is considered as an alternative, such as pomegranate peel extract and green tea which have been tested for their effectiveness against Streptococcus mutans bacteria. Objective: To provide information on the differences in the effectiveness of pomegranate peel extract and green tea on salivary pH. Methods: This is an experimental study with a pretest-posttest control group design. Normality test using Shapiro-Wilk, and statistical test using Paired T-Test and Independent T-Test. Results: There was a significant difference in effectiveness between pomegranate peel extract and green tea on salivary pH. Conclusion: Pomegranate peel extract is able to increase salivary pH while green tea lowers salivary pH. This difference in effectiveness allows for different indications to take advantage of the two types of herbs.
