Changes on transmittance mode of different composite resins

The purpose of this study was to evaluate the transmittance of seven different composite resins. Ten specimens were prepared (10 mm diameter, 2 mm thickness) for each experimental group, as follows: G1- Charisma® A2 (Heraeus-Kulzer); G2- FiltekTM Supreme A2E (3M/ESPE); G3- FiltekTM Supreme A2B (3M/ESPE); G4-FiltekTM Supreme YT (3M/ESPE); G5- Esthet-X® A2 (Dentsply); G6- Esthet-X® YE (Dentsply); G7- Durafill® A2 (Heraeus-Kulzer) and G8- FiltekTM Z-100 A2 (3M/ESPE). The transmittance mode was measured using a UV-visible spectrophotometer (Cary Instruments) at 400-760 nm. The specimens were e...
