Purpose: The purpose of this study is to evaluate the antimicrobial activity on the dental bur with fluoride for S. mutans.

Materials and methods: 0 ppm, 300 ppm, 500 ppm, 1,000 ppm, 1,450 ppm fluoride ion is added to a specimen. S. mutans was incubated for 24 hours, the number of S. mutans were counted. Kruskal-Wallis and Mann-Whitney analysis were used SPSS 25.0 (IBM SPSS 25.0, Chicago, IL, USA).

Results: The mean S. mutans counts of 0 ppm, 300 ppm, 500 ppm, 1,000 ppm, and 1,450 ppm were 374.0 ¡¾ 12.6, 251.0 ¡¾ 66.7, 111.4 ¡¾ 35.6, 41.6 ¡¾ 11.7 and 13.2 ¡¾ 4.6, respectively. All groups except the control and 300 ppm showed statistically significant.

Conclusion: Thus, more than 500 ppm fluoride ion showed the statistically significant antimicrobial activity. 1,450 ppm group showed the highest antimicrobial activity. This study showed the clinical possibility for dental caries protection and antimicrobial activity of dental bur.
