Summary
Resin coating finishes significantly improve the long-term appearance of composite dental restorations. Coated composites maintained luster, color, and smoothness better than uncoated ones after one year.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Surface Engineering
Background:
- Composite restorations with quartz fillers often exhibit surface roughness post-treatment.
- This roughness leads to marginal discoloration and staining, compromising aesthetics.
- Resin finish coatings are a potential solution to improve surface properties.
Purpose of the Study:
- To evaluate the durability of two resin coating materials on two composite brands.
- To compare the long-term effects of resin coatings on restoration aesthetics and surface integrity.
Main Methods:
- Two brands of composite restorative materials were used.
- Two types of resin coating materials were applied.
- Restorations were evaluated for luster, color match, and surface smoothness after one year.
Main Results:
- Coated composite restorations maintained significantly better luster, color match, and surface smoothness after one year compared to uncoated ones.
- The integrity of the resin coating was crucial for sustained aesthetic and surface quality.
Conclusions:
- Resin coating finishes enhance the longevity of aesthetic and surface properties in composite restorations.
- Intact resin coatings are essential for preserving the color match, luster, and smoothness of dental composites over time.
