Thermocycling effect on mechanical and tribological characterization of two indirect dental restorative materials
Abstract
The purpose of this study is to evaluate the effects of aging by thermocycling on the mechanical and tribological properties of two indirect filling commercial resin-based restorative composite materials. The studied composites are referenced by the capital letters: A and B. The commercial trade names are omitted, to avoid commercial references. Forty specimens of each material were produced and divided into three groups: a control group not subjected to aging, and two groups, T-1 and T-2 submitted to different thermocycling conditions. The studied properties were surface roughness, elastic modulus (determined dynamically by impulse excitation of vibration, and statically by four-point bending test), flexural strength and work of fracture (four-point bending test), micro-hardness (Vickers micro-indentation) and coefficient of friction (scratch test). From this study, it was possible to conclude that Composite A, in addition to having better mechanical properties, is less affected by thermocycling than Composite B, which suggests that it will better withstand the stresses, both mechanical and thermal, which it is subjected to. It is also possible to infer that the thermocycling regimen proposed by Standard ISO 11405 (Dental materials-testing of adhesion to tooth structure, 2003) is not sufficient to adequately simulate the degradation caused by the oral environment on current commercial resin-based restorative composites.
