ABSTRACT
BACKGROUND AND OBJECTIVES: This study estimates the in-vitro release of bisphenol-A (BPA) from Tetric Evoceram, Posterior EverX GC, and SDR Flow Plus bulk-fill composites: a) before polishing, b) 24h after polishing, and c) 72h after polishing.
MATERIALS AND METHODS: Twelve specimens (4mm diameter, 3mm height) from each composite were prepared. Polymerization was done using a 3M ESPE- Elipar LED light curing unit. Specimens were split into two groups:
• GROUP 1 (n=6): Immersed in 2ml of 75% ethanol.
• GROUP 2 (n=6): Polished and then immersed in 2ml of 75% ethanol.
Specimens were stored for 24h, then for 3 more days. BPA levels were measured using High-Performance Liquid Chromatography (HPLC).
RESULTS: All composites released BPA, with higher levels at 24h than at 3 days. Polished groups showed lower BPA release than unpolished. Tetric Evoceram released more BPA than EverX Posterior and SDR Flow Plus.
CONCLUSION: BPA release decreased over time and with polishing. Tetric Evoceram showed higher BPA release than the other composites.
