Abstract
The present study aimed to evaluate the validity of resin infiltration in improving color stability after tooth whitening. Enamel samples were extracted from 40 healthy bovine upper incisors, and primary staining and whitening were performed. After that, specimens were randomly divided into 3 groups : resin infiltration group (n = 15, RI group), resin adhesive group (n = 15, RA group), and control group (n = 10). Secondary staining was performed on all samples. Coloration was assessed 5 times as follows: initial color, immediately after staining, after whitening, after resin application, and after secondary staining. Color was measured using a spectrophotometer and recorded by using the CIE L*a*b* color space. The color changes after primary staining for the RI, RA, and control groups were 12.16 ± 3.50, 12.16 ± 3.38, and 15.81 ± 6.39, whereas those after secondary staining were 15.21 ± 7.19, 15.93 ± 4.31, and 26.62 ± 17.89. Color changes after secondary staining showed a significant difference between the RI and control groups. In the within-group comparison between primary and secondary staining, there was no significant difference found in the RI group only (p = 0.26). The results
suggest that Color stability after tooth whitening can be improved using resin infiltration.
