Abstract

Purpose: It is assumed, that, by following the manufacturers’ instructions regarding the polymerization methodology and using two curing lamps with different technologies, the result will be the same in terms of degree of conversion of the monomers. Materials and Methods: Two commercial adhesives and one experimental adhesive were taken into study. The samples were polymerized with two different light source and analyzed by FTIR techniques. Results: The results of the statistical tests showed there is a significant difference between the two sources of polymerization only in the case of the adhesive system which does not use camphorquinone as a photoinitiator. Conclusion: The permanent evolution of light curing materials and of their photoinitiation systems may lead to a gap between the polymerization capacity of the common light sources and the real needs of the materi.
