Abstract. The paper presents the results of strength tests of lateral teeth with 1st class cavities reconstructed with various bonding systems, i.e. self- and selective bonding systems as well as for filling with additional etching with orthophosphoric acid. In all cases a nano-hybrid, light-cured composite material was used in a layered (sandwich) cavity filling processing. The strength tests were done with the use of Instron 4465 strength machine for loadings simulating the features of proper lateral teeth occlusion. The analyses of the results were done with respect to the following quantities: ultimate force, total displacement and work to fracture. The results were compared with reference ‘healthy’ lateral teeth group. Analysis of the results proves that the type of bonding system has a significant effect on the values of individual strength parameters of the tested tooth samples. From the mechanical point of view the best results were obtained for self- and selective bonding system when comparing with additional etching procedure. However, regardless on the type of bonding system, the mechanical properties of teeth subjected to dental treatment are significantly lower than those for the ‘healthy’ teeth.
