Summary
Self-etching primers significantly improve the marginal adaptation of compomer restorations in both enamel and dentin. This contrasts with one-bottle adhesives used with the total-etch technique, showing better results for primers.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Adhesion Science
Background:
- Compomers are widely used in dental restorations.
- Achieving optimal marginal adaptation is crucial for restoration longevity and preventing secondary caries.
- Different adhesive systems and application techniques can influence marginal integrity.
Purpose of the Study:
- To evaluate the marginal adaptation of compomer restorations using various adhesives.
- To compare the performance of self-etching primers versus one-bottle adhesives.
- To assess adaptation in Class V cavities with enamel and dentin margins.
Main Methods:
- In vitro study using 80 extracted human teeth with Class V cavities.
- Tested adhesives included one-bottle systems (Prime & Bond 2.1, Syntac SC, Espe OSB) and self-etching primers (Rasant F 2000, Prompt L Pop).
- Marginal adaptation was quantitatively analyzed using SEM after thermocycling.
Main Results:
- Self-etching primers demonstrated significantly better marginal adaptation in both enamel and dentin.
- One-bottle adhesives showed improved adaptation when used with the total-etch technique.
- Statistical analysis confirmed significant differences (p < 0.05).
Conclusions:
- Self-etching primers enhance the marginal adaptation of compomer restorations, particularly in enamel.
- The choice of adhesive system and etching technique impacts the marginal integrity of compomer restorations.
