In this study, the changes in occlusal strength and oral environment before and after the use of natural gargles containing cinnamon were confirmed. This study involved 42 adults aged 19 or older living in Busan from November 25 to December 2, 2023. Twenty-one people were randomly selected for each of the regular and natural gargles. In this study, the group using natural gargles confirmed an increase in saliva buffering power, a decrease in O'Leary index, and an increase in occlusal strength. Through this, it was confirmed that natural gargles containing cinnamon are helpful in improving the oral environment and occlusal strength.

Gargle solution has typically been used for the prevention of oral infectious disease such as dental caries and periodontitis. However, the use of most gargle solutions is controversial in application for children because some gargle solutions have harmful side effects. Electrolyzed water is generated by passed an electric current and has antimicrobial activity. The purpose of this study was to investigate and compare the efficacy of electrolyzed water in various conditions for eliminating cariogenic bacteria. Electrolyzed water was generated by a platinum electrode in the presence of sodium chloride at various concentrations. Streptococcus mutans and Streptococcus sobrinus were cultivated into a brain heart infusion broth. After harvesting planktonic bacteria, the pellets were treated with the electrolyzed water and commercial gargle solutions and plated on a mitis-salivarius agar plate. Also, the anti-biofilm activity of the electrolyzed water and commercial gargle solutions was investigated after biofilm formation of S. mutans and S. sobrinus. The bacteria in the biofilm were plated onto a mitis-salivarius agar plate. The plates were incubated, and the colony forming unit was measured. The electrolyzed water containing sodium chloride showed significant antibacterial activity against S. mutans and S. sobrinus as well as some gargle solutions. Furthermore, the electrolyzed water had more disruptive effect on the biofilm of S. mutans and S. sobrinus and killed more bacteria in the biofilm than commercial gargle solutions. The results demonstrate that electrolyzed water may be a useful gargle solution for prevention of dental caries.

In this study, natural mouthwash was developed based on natural substances based on cinnamon and ginger, which are familiar to the public, to check the effectiveness of mouthwash and changes in microbial distribution. This study was conducted on 24 people who fully explained the purpose and method of the study and agreed to participate among those who visited D University from October 2021 to December 2021. The subject's oral cavity was examined and placed in three groups to have similar conditions, and after using mouthwash for a week, a survey, saliva test, breath measurement test, and PCR test were performed. As a result of the experiment, the amount of saliva after using natural mouthwash increased compared to the control group (P<0.05). In the comparison of bacteria, it was confirmed that Pg and Fn bacteria decreased after using natural mouthwash (Pg t=4.852, P=.002, Fn t=2.888, P=.023). Following this study, it is expected that research on the development and efficacy of natural mouthwash will be conducted through various clinical applications, which will be useful in real life and dental care institutions.
