Abstract

OBJECTIVES
This study aimed to observe the decrease in tooth color after home and office bleaching due to consumption of juice, soda, and coffee over a period of one year.
METHODS
We obtained written consent from 30 subjects, who were divided into two groups i.e., home bleaching and office bleaching groups. They were treated with opalessence® and Zoom2 whitening gel, and the color of their teeth was assessed using shade Eye-NCC over a one-year period. A self-describing questionnaire was used to determine the frequency of juice, soda, and coffee consumption.
RESULTS
The changes in color were measured before and after 1 day, 1 month, 3 months, 6 months, and 12 months. Although the tooth color slightly changed after 12 months, the teeth were brighter than the original color. Consumption of juices, sodas, and coffee is thought to be associated with decrease in tooth color, although the change was not statistically significant.
CONCLUSIONS
The ΔE* values showed that the tooth bleaching effect remained for 12 months. Consuming a normal amount of juice, sodas, and coffee does not significantly reduce tooth color after tooth bleaching.
