Effects of Commercially Available Herbal Mouthrinses on the Color Stability of Different Resin-based Composite Restorative Materials

Colour match is one of the most important physiognomies of aesthetic restorative materials. Functional maintenance of colour throughout the lifetime of restoration is significant for durability of treatment.

Objectives: Aim of this study is to assess the changes of three commercially available herbal mouthrinses to keep a record on color permanency by using four different composite restorative materials.

Methods: specimens (10x2 mm) were prepared in disc shape from each of the following materials: All composites containing nanohybrid particles:

Tetric N-Ceram (Ivoclar Vivadent, India), FiltexZ250 (3M/Espe), Solare X (GC, India Dental), Charisma (Heraeus Kulzer, India).

After preparation of specimen they were kept in distilled water at 37°C for 24 hours. With the help of colorimeter initial change in color values of each specimen were recorded. After recording the initial change in color, 10 specimens from each group were immersing in 1 of the 3 mouth rinses and distilled water was kept as control. The specimens were stored in 20 mL of each mouth rinse (Oramint herbal, Hiora-K, Dentobac herbal) for 12 hours. After immersion, the color values of all specimens were re recorded, and the color change was ΔE*ab was observed and calculated.

Results: All specimens exhibited color changes after immersion, and there was slight difference that was noticed among restorative materials and mouth rinses (P<.05).

Conclusion: According to results of present study, effects of oramint 3mouth rinses caused more color change of the materials used. And among those, FiltexZ250 composite material retained more stain.
