Comparative Evaluation of Antiplaque Efficacy between Essential Oils with Alcohol-Based and Chlorhexidine with Nonalcohol-Based Mouthrinses

The aim of this study is to compare the antiplaque efficacy of alcohol-based mouthwash with essential oils and nonalcohol-based chlorhexidine mouthrinse in 4 days plaque re-formation study. The current research paper is double-blinded, parallel designed clinical trial that was conducted in the Department of Periodontics and Oral Implantology, Kalinga Institute of Dental Sciences, Bhubaneswar. This included ninety dental students of Bachelor of Dental Surgery curriculum (in the age range from 20 to 24 years) Professional cleaning with scaling and polishing was carried out to acquire a zero plaque and gingival index (GI) for all ninety patients at baseline. Ninety patients were randomly divided into three groups with thirty patients in each group named as Group A, B, and C, respectively. Two commercially available mouthrinses, one containing alcohol (labeled as Solution (A) and one without alcohol (labeled as Solution (B) were placed in identical bottles and distributed to Group A and Group B patients. Whereas, the Group C patientswere instructed to use warm saline mouth rinse. The statistical analysis was performed using the Statistical Package for the Social Sciences software (Version 18). Essential oils with an alcohol-based and chlorhexidine (CHX) alcohol-free mouthrinse (0.2%) groups compared to normal saline showed significant reductions in GI and PI scores.( < 0.0001). The antiplaque efficacy of both alcohol-based mouthwash with essential oils and nonalcohol based CHX mouthwash were found to be equally effective in 4 days of plaque re-formation.
