Proximal surfaces of both anterior and posterior teeth frequently present dental caries, as a result of complex coronal morphology and other associated factors which favors bacterial microfilm retention. In this article we present the second part results of a cross-sectional study, using a questionnaire that was distributed to a number of 110 Romanian dentists. We investigated the most used dental materials and techniques and correlations with oral restorations longevity, and also the failures and patients‘ complaints. The results indicate a modern, up to date approach of direct restoration in adjacent teeth from Romanian interviewed dentist.
