Resin-based composites and dentine-bonding agents. Which, who and why? A study in the East of Scotland.

Aims: To determine which resin-based composite (RBC) and dentine-bonding agent (DBA) systems were most widely used by a random convenience sample of dentists in the East of Scotland, by whom they were used, and what influenced the dentists' choice when buying/using a particular RBC and DBA.

Methods: A cross-sectional questionnaire-based study was conducted from June to December 2006. A questionnaire was compiled and, following a short pilot and revision, 250 questionnaires were randomly distributed to dentists attending vocational training/general professional training study days, continuing education courses and various dental meetings.
