Perubahan Warna Resin Komposit Nanofiller Setelah Perendaman dalam Minuman Susu Fermentasi (Penelitian In Vitro)

Abstract

Composite resin is one of filling material anterior that popular because it had advantages in the field of aesthetic and the same color as teeth. Nanofiller composites had mechanical properties better than microhybrid and could maintain smoothness during using as microfiller. Composite resin’s color could change in the oral cavity, which could be caused by low pH beverage. Objective of this research to determined the influence of immersion in the fermented milk on the discoloration of nanofiller composite resin. In addition to know the difference of nanofiller composite resin discoloration in the fermented milk for 6, 12, and 18 hours. The type of this research was experimental laboratories with pretest and post test group design. 24 samples immersed in fermented milk for 6, 12, and 18 hours. The measurement of the color changing was using optical spectrophotometer to determine the light intensity value. To know the value of the discoloration was appeared from the value of the light intensity that appeared on the optical spectrophotometer. Analysis of data by using Paired-T Test and One Way Annova. The value of light intensity test was higher after treatment. The average difference of light intensity values before and after treatment was highest in 18 hours group and the lowest in 6 hours group. The discoloration of nanofiller composite resin after immersed in fermented milk had significant difference.
