Visible light polymerizing composite resins have been the material of choice for esthetic restorations.In the last few decades, adhesive dentistry has evolved remarkably, greatly due to the development and incorporation of new monomers, new initiation systems and filler technologies which improve the physical properties of these materials. Composite resins, however, have one deficiency : they all contract, causing dimensional changes, during photopolymerization. Such contraction is termed polymerization shrinkage.The purpose of this book provides you with an in depth understanding of the...
