Background and Objectives: This study investigated the antibacterial efficacy of Sesewanua (Clerodendrum fragrans Wild) extract as a mouthwash alternative to mitigate oral bacteria, particularly Streptococcus mutans.
Materials and Methods: A quasi-experimental design was employed with a cohort of 100 female students, divided into four groups to assess varying concentrations (1%, 2%, and 4%) of Sesewanua extract, along with a purified water control. The extraction process involved mechanical grinding followed by maceration with 70% ethanol to maximize the extraction of bioactive compounds. Microbiological analysis was conducted post-intervention to measure the reduction in bacterial counts.
