Abstract

Background

Consumption of certain beverages may affect the esthetic and physical properties of the resin composite, thereby undermining the quality of restorations.

Aim

To analyze the effect of three beverages (cola, coffee, tea) on color stability and surface roughness of three different types of resin composites at various time intervals in vitro.

Materials and methods

Nano, microhybrid and hybrid resin composites were used. Each material was randomly divided into four equal subgroups of 10 samples each according to the beverages used (cola, coffee, tea, distilled water). The samples were immersed in each beverage for 1, 15 and 30 days. Surface roughness and color changes measurements were noted at the baseline—the first, fifteenth and thirteenth day.

Results

It was found that nanoresin composite followed by microhybrid and hybrid showed least surface roughness and color change. The Coke beverage subgroup showed more surface roughness and the subgroup coffee has shown more color changes with respect to other subgroups.

Conclusion

All specimens showed discoloration after completion of the test period which was visually perceptible and clinically unacceptable.

At the end of 30th day, among the materials, nanofilled composite resin showed comparatively less surface roughness and color change than microhybrid and hybrid composite resins.
