Understanding the details

Filler Material – Composites are essentially made up of a filler material inside a resin matrix. Many newer composites feature nanoscale filler materials with particles as small as 20-50 nm which makes them easier to polish, improves wear resistance and durability, and reduces shrinkage.
Shade – Nothing is worse than picking a shade via the sample tab, and finding the completed restoration doesn’t quite match the tooth, so compare the shades of the cured composite with the shade system you use to create a frame of reference. It also helps to choose a composite system with variable translucencies, especially for anterior cases. This allows you to place opaque layers to simulate dentin and translucent layers to simulate enamel.
Handling – Whatever your instrument of choice happens to be, it is important to be able to manipulate the composite in increments useful to you. The composite should not stick to your instrument, and it should adapt to the cavity preparation in a way that is neither too thick nor too pliable. Always try a new composite in your hands before purchasing.
Shrinkage – Be aware of the percentage of shrinkage. The lower the number, the more likely the material will provide good marginal integrity in your cavity preparation.
Radiopacity – Most modern composites offer good radiopacity, allowing you to clearly see the restoration on future diagnostic images.
