Effect of fluoride release on the polished surface after polishing with a bur containing fluoride

Abstract

This study aimed to evaluate the fluoride release amount on the polished surface after polishing with a bur containing fluoride. The point-shape dental burs and disk-shape specimens containing 1,450 ppm fluoride were fabricated. The fluoride released on the dental bur was measured after 1, 3, 7, and 9 days from the disk-shaped specimens (n=5). The point shape dental bur polished the conventional composite resin surface 5 times during 5 seconds at 3,000 rpm. The polished composite resin surface was measured the fluoride release amount after 1, 3, 7, and 9 days. IBM SPSS Statistics ver. 25.0 (IBM Corp., Armonk, NY, USA) was used for statistical analysis. The dental bur containing fluoride were released at 71.68±3.82 ppm fluoride after 1 day, 75.52±2.19 ppm after 3 days, 77.5±1.86 ppm after 7 days, and 77.58±1.30 ppm after 9 days. The polished surface with the point shape dental bur containing fluoride was released at 7.98±0.62 ppm fluoride after 1 day, 8.48±0.65 ppm after 3 day, 8.80±0.41 ppm after 7 days, and 8.75±0.35 ppm after 9 days. The application of dental bur containing 1,450 ppm fluoride showed the possibility of preventing dental caries and exerting an antimicrobial effect.
