Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the effect of novel mouthrinse formulations containing bamboo salt, magnolia bark and centella asiatica extracts on gingivitis and dental plaque. Participants uses mouthrinses which contain bamboo salt, magnolia bark and centella asiatica extracts and the same participants will also use placebo for tooth brushing by cross-over design.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a randomized clinical intervention study with a cross-over design. The subjects are randomly allocated to one of the three experimental groups: 1) the control; 2) ASM group for aqueous single-phase mouthrinse; 3) OTM group for oil-water two-phase mouthrinse. The experimental mouthrinses all contain sodium fluoride and the ASM and OTM contain additional ingredients of bamboo salt, magnolia bark and centella asiatica extracts. For the OTM, 50% essential oil is added to create an oil-water two-phase mouthrinse. Subjects are instructed to use the prescribed mouthrinse to gargle their mouth for one minute, twice daily for two weeks. The completion of each experiment regimen is followed by a 2-week washout period, after which the subjects of each group were permutated to the next mouthrinse trial until all three groups underwent the three mouthrinse trial regimen.
