Background and Purpose. Fixed orthodontics may be associated with accumulation of Mutans Streptococci (MS), enamel demineralization, and an increased number of carious lesions, predominantly in sites adjacent to brackets. This study was undertaken to assess the effectiveness of Listerine, Oral-B, and Ortho-kin on the accumulation of MS in plaque around orthodontic brackets. Materials and Methods A double-blind randomized cross-over clinical trial on 25 orthodontic patients, classified into 6 groups was done to assess MS in plaque and saliva with the side specific modified Strip-Mutans technique and the plaque (PI) was measured before and after rinsing using 3 types of commercial mouth-rinses. A washout period (3 weeks) was awaited between using each mouth-rinse and the data was analyzed via Wilcoxon and Kruskal Wallis statistical tests. Results. This study of 25 patients, 5 men and 20 women, with an average age of 1 9 Β± 6 / 3 assessed the effectiveness of mouth-rinses on MS. Our results showed that Ortho-kin had a better effect than Oral-B and Listerine ( 𝑃 < 0 / 0 9 ). Ortho-kin also had better effects than Oral-B and Listerine on plaque accumulation ( 𝑃 < 0 / 0 0 1 ). Conclusion. Ortho-kin showed better effects on decreasing MS and PI because it contained chlorhexidine.
