This study aimed to evaluate the effect of resin infiltration, remineralization and their combination on the color restorability of artificially acid demineralized enamel lesions in addition to the color stability of the aforementioned treatments after acid challenge and immersion in common staining beverages. A hundred and five specimens were obtained from the buccal and lingual surfaces of permanent posterior teeth. Demineralized enamel lesions were artificially induced in all samples except for positive control. All specimens were randomly divided into 5 groups (n = 21) according to the treatment applied to the artificially demineralized enamel lesion: sound enamel (+ ve control), demineralized enamel (-ve control), resin infiltration, remineralization using Clinpro™ White Varnish and remineralization using Clinpro™ White Varnish followed by resin infiltration. After treatment, all specimens were subjected to pH cycling daily for 28 days and immersed in one of three beverages (coffee, tea and artificial saliva) for 30 min daily. Color measurement using the Commission International de l’Eclariage (CIE) L* a* b* values, using Cary 5000 Spectrophotometer (Agilent Technologies, NY, USA) was performed three times (baseline, after treatment and after pH cycling and immersion in beverages). Results were collected and statistically analyzed. The treatments applied to demineralized enamel lesions had a significant effect on color restorability (p < 0.001). The highest color difference values between baseline and after treatment (ΔE1) among the treatment groups was found in remineralization group (1.99 ± 0.13) while the lowest was found in remineralization & resin infiltration (0.86 ± 0.12). Regarding color stability, both treatments and beverages had a significant effect. The highest color difference values between after treatment and after pH cycling and immersion in beverages(ΔE2) was found in remineralization & resin infiltration- coffee group (9.05 ± 0.67) while the lowest values were found in the remineralization-saliva group (0.73 ± 0.12). All post hoc pairwise comparisons were statistically significant (p < 0.001) in all groups. Remineralization combined with resin infiltration can improve the esthetic outcome of demineralized enamel lesions compared to each treatment alone. However, the color stability of this combined treatment when subjected to coffee and tea is inferior to each of the treatments alone.
