– Polyethylene tubes were filled with different types of composite resins using either the bulk‐packing technique or the syringe injection technique. The porosity of the specimens was studied. Specimens made by light‐activated systems were less porous compared to specimens made by two‐paste systems. Use of the injection technique was followed by a reduction in porosity in both groups compared to use of the bulk‐packing technique.
