| Summary: | Objective: To determine the color stability of two types of flow composites immersed in artificial saliva with three different pH
values, using Vita Easy-shade digital colorimeter. Materials and methods: An experimental, comparative and in vitro study
is proposed using 90 discs made from two fluid resin markings of 10mm diameter and 1mm thickness, light-cured using the
same lamp, after being immersed in distilled water and made a first registration color using Easy-shade digital colorimeter,
the samples were divided into three groups and in turn into three subgroups, becoming submerged in artificial saliva with
different pH of 5, 6 and 7 respectively for 7 days, making a new color taking by digital colorimeter, later the samples were
submerged in beet juice as a pigmenting agent for 24 hours, after this period they were washed to eliminate pigment residues
and made a third color take. Results: Greater color change occurred in the discs that were subjected to artificial saliva with
pH 5 (p = 0.000), the minor color changes occurred in the discs that were immersed in artificial saliva with pH 7. Conclusions:
The pH salivary 5 or acid, caused greater change in color without significant difference between the materials tested |
