Objectives: the objective of the current study is to investigate and compare the color masking of WSLs treated by (ICON) resin infiltrate and fluoride releasing sealant (PROSEAL) using photographic assessment.
Patients and Methods: This study is a randomized controlled trial (RCT) that included a total of 36 children who were recruited from the outpatient clinic of the Pediatric Dentistry and Dental Public Health Department – Faculty of Dentistry Ain-Shams University. Children having white spot lesions were randomly allocated in either the ICON (Group A) or the PROSEAL (Group B). The assigned material was then applied to the lesions and the color change was measured immediately (A1) and on follow-up intervals of 3 (A2) and 6 months (A3), using digital photographic assessment.
Results: The color difference (ΔE) of WSLs in (group A) showed a significant difference between the pretreatment measurement and all the subsequent measurements. However the ΔE wasn't significantly different between (A1) and (A 2) or (A3). Conversely, different follow-up intervals in (group B) were found to be significantly different from each other. Color assessment after 6 months showed that (group A) had a higher percentage of completely masked lesions compared to (group B), however the difference between the two groups wasn't statistically significant.
Conclusions: Both ICON and PROSEAL were successful in masking of WSLs in primary teeth. ICON infiltrant, however showed immediate masking effect. On the other hand, PROSEAL displayed slow progressive improvement in the appearance of WSLs, and it achieved a proper masking effect in 6 months.
