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?
Three pairs of buccal cervical supragingival carious lesions in anterior teeth
Complete and normal occlusion
Good oral hygiene
Willingness to attend follow-up and recall visits for 2 years
Teeth requiring direct pulp capping
Poor oral hygiene or failure to complete the oral hygiene phase
Chronic periodontitis
Pulpitis or non-vital teeth
Crossover
one-step finishing and polishing system.
Other intervention• Each class V restoration will be restored with an ormocer-based bulk-fill flowable composite material or methacrylate-based restorative according to the manufacturer's instructions for use, and then each class V restoration will be subjected to a one-step finishing and polishing system.
two-step finishing and polishing system.
Other interventionEach class V restoration will be restored with an ormocer-based bulk-fill flowable composite material or methacrylate-based restorative according to the manufacturer's instructions for use, and then each class V restoration will be subjected to a two-step finishing and polishing system.
three-step finishing and polishing system.
Other interventionEach Class V restoration will be restored with an ormocer-based bulk-fill flowable composite material or methacrylate-based restorative according to the manufacturer's instructions for use, and then each Class V restoration will be subjected to a three-step finishing and polishing system.

Treatment groupsSee each treatment group below.
FDI criteria score-aesthetic properties (A1 surface luster and surface texture; A2 Marginal staining; A3 color match), Functional (F1 Fracture/Retention; F2 marginal adaptation), biological (B1 caries at restoration margin)
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. Unit of Measure: FDI score 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. Unit of Measure: FDI score 3. Biological properties Restoration assessment of B1 (caries at restoration margin) according to the revised 2023 FDI criteria. Lower scores indicate better performance. Unit of Measure: FDI
