Creep and recovery of composites for use in posterior teeth during static and dynamic compression -

The deformation behavior of 8 different posterior composites under uniaxial static and dynamic compression have been investigated.

Conversion in different depths of ultraviolet and visible light activated composite materials. -

Studies by means of infrared multiple internal reflection spectroscopy of ultraviolet and visible light polymerized composite resin materials indicated that the degree of conversion below the surface is nearly constant for most of the materials investigated until a depth is reached where the degree of conversion rapidly decreases.
