Abstract
Objectives: This study aims to examine the effects of silver diamine fluoride and potassium iodide (SDF/KI) treatment on the possible color changes and the microtensile bond strength of composite restorations to carious dentin in different dentitions.
Material and methods: A total of 48 sound human teeth were utilized in this study. Twenty-four primary molar teeth were divided into two groups. Each group has 12 teeth; group 1 received no pretreatment, while group 2 received SDF/KI treatment. Also, 24 permanent premolar teeth were divided into two groups. Group 3 received no pretreatment, and group 4 received SDF/KI treatment. For 7 days at 25 °C, every sample was submerged in a demineralizing solution. Following the manufacturer's guidelines for SDF/KI treatments, exposed dentin surfaces were promptly preserved in artificial saliva (pH 7.4) for 14 days. On the prepared teeth surfaces of the nontreated groups, deionized water was administered rather than SDF/KI. A self-etching bonding agent was used, and a 4-mm-thick composite restoration was constructed. Evaluations were conducted on color measurement, microtensile bond strength, and mode of failure.
Statistical analysis: The groups were compared using a one-way analysis of variance test, and a post hoc test was used for pairwise comparisons.
Result: Regarding color measurement, in deciduous dentition, there were no statistically significant differences between the groups. Additionally, there is no discernible variation in ΔE values among various pretreatment groups in the permanent dentition. Microtensile bond strength did not differ significantly between permanent and deciduous teeth.
Conclusion: A 14-day delay in the application of composite restoration can successfully conceal the color of SDF/KI without compromising the microtensile bond strength.
期刊介绍：
The European Journal of Dentistry is the official journal of the Dental Investigations Society, based in Turkey. It is a double-blinded peer-reviewed, Open Access, multi-disciplinary international journal addressing various aspects of dentistry. The journal''s board consists of eminent investigators in dentistry from across the globe and presents an ideal international composition. The journal encourages its authors to submit original investigations, reviews, and reports addressing various divisions of dentistry including oral pathology, prosthodontics, endodontics, orthodontics etc. It is available both online and in print.
