Summary
Finishing aesthetic dental materials is crucial for preventing plaque buildup. "Gommini" polishers create smoother surfaces than abrasive disks, offering superior results for composite and compomer restorations.
Area of Science:
- Conservative Dentistry
- Dental Materials Science
- Surface Finishing Techniques
Background:
- Unfinished aesthetic dental materials exhibit surface irregularities, promoting pigmentation and bacterial plaque accumulation.
- Proper finishing of aesthetic restorations is a critical, non-optional step in conservative dentistry.
- Finishing protocols should be planned during the initial insertion of aesthetic materials.
Purpose of the Study:
- To evaluate the effectiveness of four finishing and polishing systems on compomer and composite materials.
- To measure the surface texture changes induced by different finishing systems using a high-sensitivity profilometer.
Main Methods:
- Two aesthetic materials (compomer and composite) were prepared into 2mm thick slabs.
- Four finishing/polishing systems (Sof-Lex Pop-on, Enhance, Hawe Micro Disc, Heawe Gommini Polisher) were applied.
- Surface roughness was quantified using a Tencor-P10 profilometer.
Main Results:
- All systems showed decreased material resistance to plaque over time.
- Coarse/medium grit disks were highly abrasive, creating irregular surfaces.
- Fine/extra-fine grit disks smoothed previous abrasions, improving micromorphology.
- "Gommini" polishers were less abrasive, producing smoother, more regular surfaces efficiently.
Conclusions:
- "Gommini" polishers are preferred for achieving excellent surface micromorphology after photopolymerization.
- "Gommini" polishers effectively smooth restorations with minimal material removal.
- Disks were not considered top-quality for finishing composites and compomers.
