Aim
Plaque disclosing agents, which stain dental plaque on tooth surfaces, are commonly used by dentists to assess and educate patients about their oral hygiene. The aim of this study was to evaluate the effect of two plaque disclosing agents on the color parameters of four different restorative materials.
Material and Methods
A total of 80 disc-shaped specimens, 8 mm in diameter and 2 mm in thickness, (n=20) were prepared from three different composite resins (Filtek Z250; Charisma Diamond; Estelite Universal Flow Medium) and a giomer (Beautifil II). Baseline color measurements were made by VITA Easyshade Compact after the specimens were numbered and kept in distilled water at 37°C for 24 hours. The plaque disclosing solution Mira-2-Ton was applied to the surface of 10 specimens of each group and Propind Plaque Indicator Gel was applied to the surface of the other 10 specimens. After removing the agents from surface by washing, color measurements were made for the second time. Color changes in the specimens were calculated using the CIEDE2000 formula. One-way Analysis of Variance, Kruskal Wallis and Mann Whitney-U test were used for statistical analysis (p<0.05).
Results
After the application of Mira-2-Ton solution, clinically unacceptable color changes were observed in all groups. These Delta E00 values were determined as; Filtek Z250:2,98 ± 1,13, Charisma Diamond:7,18 ± 2,65, Estelite Universal Flow Medium:3,26 ± 1,87, Beautifil II:5,36 ± 3,03. All the groups stained with Propind gel did not show clinically relevant discoloration with no statistically significant difference between the Delta E00 values (p>0.05). The color change in specimens applied with Mira-2-Ton solution was found to be statistically significantly higher compared to those applied with Propind gel (p<0,05).
Conclusions
Considering that plaque disclosing agents may cause color changes in restorations, further studies using a wide variety of this agents and under clinical conditions are needed.
