Abstract:
Marginal integrity of indirect composite restorations is critical for clinical longevity and the timing of dentin sealing may influence the tooth-restoration interface. Therefore, it is of interest to evaluate the effect of immediate versus delayed dentin sealing on marginal integrity of indirect composite restorations. Sixty extracted premolars with standardized cavities were divided into three groups (IDS, DDS control), restored with indirect composite inlays and assessed after thermocycling using stereomicroscopy and SEM. The IDS group demonstrated significantly smaller marginal gaps and lower microleakage compared to DDS and control groups (p<0.001). Immediate dentin sealing provides superior marginal adaptation and may enhance the clinical performance of indirect composite restorations.
