Impact of Finishing/Polishing Systems on Ormocer VS Methacrylate Based Bulk Fill Flowable Composite in Class V

31. maj 2026 opdateret af: Mansoura University

Impact of Finishing/Polishing Systems on Ormocer Versus Methacrylate Based Bulk Fill Flowable Composite in Class V Restorations: Clinical Study and Laboratory Investigations

The goal of this clinical trial is to evaluate and compare. Impact of finishing/polishing systems on ormocer versus methacrylate-based bulk-fill flowable composite in Class V restorations: The main question it aims to answer is the following:

Are there any differences between finishing/polishing systems on Ormocer versus methacrylate-based bulk-fill flowable composite?

Studieoversigt

Detaljeret beskrivelse

This study will evaluate the impact of three different finishing/polishing systems on ormocer versus methacrylate-based bulk-fill flowable composite in Class V restorations on adult patients' anterior teeth. First, investigators will use an ormocer and methacrylate-based bulk-fill flowable composite in Class V restorations in anterior teeth. Then each patient will receive three different finishing/polishing systems. Investigators will follow patients at 2 weeks, 6 months, 18 months, and 24 months to assess the restorations according to the FDI criteria as esthetic properties (A1 surface luster and surface texture; A2 marginal staining; A3 color match), functional (F1 fracture/retention; F2 marginal adaptation), and biological (B1 caries at restoration margin). The results will help dentists choose the most appropriate finishing/polishing systems for Class V restoration cases.

According to the revised 2023 World Dental Federation (FDI) criteria for,

  1. Aesthetic properties Restorations will be evaluated for A1 (surface luster and texture), A2 (marginal staining), and A3 (color match). Mean (SD) scores and the proportion of clinically acceptable restorations (scores 1-3) versus unacceptable restorations (scores 4-5) will be reported. Lower scores indicate better clinical performance.

  2. Functional properties Restorations will be evaluated for F1 (fracture/retention) and F2 (marginal adaptation). Mean (SD) scores and the proportion of clinically acceptable restorations (scores 1-3) versus unacceptable restorations (scores 4-5) will be reported. Lower scores indicate better clinical performance.
