Effect of One-step Versus Multistep Polishing Protocol on Class IV Composite Restorations.

Официальное название

Esthetic Performance and Surface Roughness of Class IV Nanohybrid Composite Restorations Following One-step Versus Multistep Polishing Protocol: a Randomized Clinical Trial

Обзор

This study aims to evaluate the effectiveness of various finishing and polishing techniques for composite resins used in dental restorations, with a focus on minimizing discoloration and surface roughness over time. Discoloration due to plaque accumulation and surface staining can lead to esthetic concerns, resulting in premature restoration replacement and increased costs. Prior research highlights that esthetic failures, such as color alterations and surface staining, are key reasons for the failure of anterior restorations. Given the contradictory findings in previous studies on finishing and polishing methods, this research seeks to determine whether one-step polishing system will have the same effect as the multistep system in terms of esthetic performance and surface roughness of nanohybrid resin composite class IV restorations. The main operator will compare between OneGloss (Shofu) the intervention and Super-Snap X-treme (Shofu) the comparator. Patients will be evaluated immediately following polishing then after 3 months, 6 months, and 12 months.
