Photopolymeric materials used in dentistry are complex composites which comprises
of sometimes tens of components. The material should simultaneously carry out several
functions and corresponds to requirements of thermostability, mechanical and chemical
properties and to be nontoxic. Temperature of process, rate of polymerization and degree
of polymerization has great value in the stomatologic practice [1]. The properties are
reached due to inclusion of certain combination of monomers, inorganic fillers,
stabilizers, initiators of photopolymerization and other components in the material
structure. In this work, the influence of combination of dental composites, lamps for
photopolymerization and times of irradiation on the properties of final product was
We studied the process of photopolymerization of five composite dental
photopolymeric materials by using two lamps (Elipar FreeLight and Elipar FreeLight 2)
and apparatus Du Pont 912 DS DSC with photocalorimeter Du Pont model 930 DPC.
Highest polymerization enthalpy was achieved by Filtec Flow, while Filtec Suprem
showed the lowest enthalpy among the 5 dental composites. The reaction rate coefficient,
k, was established as well. At constant temperature, the highest k value was noted on
Filtec Z250, while Tetric Ceram showed the lowest k value. The experiments for
definition of temperature influence on polymerization process were conducted.
Subsequently, the influence of temperature on polymerization process was studied.
Polymerization of Filtec Z250 was found to be highly dependent on temperature whilst
Filtec Flow and Restorativ Z100 were the least subjected to temperature effect. Our
results also showed that Restorativ Z100 demands the least activation energy and Tetric
Ceram requires the highest activation energy among all testing materials.
