Abstract

Aim: Using of mouthwashes has become more popular recently as a result of the studies on reducing the transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The aim of this study is to examine the effect of different content mouthwashes on the color changes.
Methods: Two different resin-based CAD/CAM materials (Vita Enamic and Brilliant Crios)
were used in the study (n=32). 64 samples were prepared by taking 2 × 7 × 12 mm sized sections from CAD/CAM blocks (n=32). After the samples were kept in artificial saliva at 37° C for 24 hours, initial color measurements were made with a spectrophotometer device (VITA Easy shade V, Germany). Then the samples were kept in 3 different mouthwashes containing Cetylpyridinium chloride (Oral-B), Povidone iodine (Batiqon) and Chlorhexidine (Kloroben) twice a day for 1 minute (n=8). Color measurement of the samples was repeated on the 7th, 14th and 30th days. Color change values (ΔE00) were evaluated by one-way analysis of variance (ANOVA) and Tukey test (p<0.05).
Results: There was no statistically significant difference between the color changes of resin-based CAD/CAM blocks held in mouthwash at the end of the 7th, 14th and 30th days (p>0.05).
Conclusion: At the end of the 30th day, color change was observed below the noticeable threshold value (ΔE00>0.8) in the hybrid ceramic CAD/CAM block samples (Vita Enamic) . In composite-reinforced CAD/CAM samples (Brilliant Crios), only Povidone-iodine-containing mouthwash produced color change above the noticeable threshold value (ΔE00>0.8), while Chlorhexidine and Cetylpyridinium chloride did not produce a noticeable change.
