EFFICACY OF ORAL REFRESHER STRIP CONTAINING FIVE TYPES OF ESSENTIAL OILS ON ORAL MALODOR

摘要

Objective: The aim of this study was to determine the efficacy of an oral freshener strip containing five types of essential oils on oral malodor. Methods: This study was a clinical trial using cross-over, randomized-double-blind, and placebo-controlled trial design with 15 male participants. The measured parameters were tongue coating, organoleptic score, and volatile sulfur compounds (VSCs) score. Results: After the essential oil strip dissolved in the oral cavity, there was no significant reduction in tongue coating, but there was significant reduction (p<0.05) in the organoleptic score until 60 minutes after dissolved and VSCs until 30 minutes after dissolved. Conclusion: Essential oil strips are more effective than placebo strips in reducing oral malodor.
