[Clinical evaluation of a posterior photopolymerizing composite: results 4 years after application].

The aim of this study was to examine clinical results of class I and class II composite restorations of forty two posterior teeth, considering pulpal vitality, dentinal sensitivity, marginal integrity, contact areas, color, gingival irritation and secondary decay. The restorations were evaluated over a four-year period. The results are considered satisfactory both from a chemical-physical and biological point of view. The Authors wish to outline the importance to improve the operative technique to minimize the disadvantages of these materials and to obtain better results. The Authors propose to carry out a later control to confirm these results.
