Abstract

Clinical performance of restorative materials and their adhesive interfaces can be affected by erosion after rehabilitation of erosive lesions. The aim of the present in vitro study was to evaluate the erosive wear resistance and adhesive bond strength of direct restorative materials, using four different testing tools. Four aesthetic dental filling materials were included in the study: a universal nano-filled composite, a light curing posterior filling composite resin, a tooth-coloured polyacid modified composite resin (compomer) and a coloured compomer indicated in restorations of deciduous teeth. Fifteen specimens were prepared according to each of the four tested restorative materials. Following manufacturers' instructions for the manipulation/ mixing of the materials, adhesive systems and unset pastes were placed in cavities of 4mm length, 3mm width and 1mm depth prepared in bovine extracted teeth and cured. After 24 hours of rehydration in distilled water, each group was immersed in erosive solutions chosen for testing: 1% citric acid and 0.02% phosphoric acid. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) were used in order to analyze the degrees of erosive wear of the materials following exposure to the various erosive solutions. Also, microtensile bond strength (μTBS) was made and the obtained data was analyzed by one-way ANOVA test and two-sample t-test, with a level of significance that was set at p<0.05. Experimental results reveal that the dental filling materials showed different behaviour under the same erosive conditions. These findings suggest that erosive wear resistance of direct dental restoratives could influence their longevity in intraoral acidic conditions.
