| Abstract | ||
| Aim: The present study aims to evaluate and compare the ability of different fluoride-releasing restorative materials combined with either potassium iodide (KI) or an opaquer to mask the discoloration produced subsequent to silver diamine fluoride (SDF) and to assess their color change over time. Materials and methods: Fifty-four carious primary molars were collected and randomly divided into three main groups according to the tested material [Glass Ionomer (Group A), Giomer (Group B), and Zirconomer (Group C)]. Each group was further subdivided according to the addition of either SDF only (control), SDF+Potassium iodide (intervention 1), or SDF+Opaquer (intervention 2). Color assessments using a spectrophotometer were performed after restoration placement, after 24 hours, and after 1 week. Results: The intragroup comparison revealed a significant change in color (ΔE value) in all groups between the 24-hour and 1-week time intervals. Group A demonstrated the greatest amount of discoloration at all periods compared to groups B and C. KI and opaquer significantly reduced the SDF discoloration (p<0.001) under the different restorations. Group A had the greatest (ΔE) value, followed by Group B, while Group C had the lowest value. Values of various materials were found to be significantly different from one another (p<0.001) in post hoc pairwise comparisons. Conclusion: The use of KI or opaquer following the SDF application is preferable over SDF alone for masking the black staining. Additionally, zirconia-reinforced glass ionomer may be able to mask SDF-produced discoloration more effectively than both giomer and glass ionomer. | ||
