Resin-Based Composites and Dentine-Bonding Agents. Which, who and Why? A Study in the East of Scotland

Abstract

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. Data from the completed questionnaires were collated and analysed. Results A total of 138 questionnaires were returned, giving a response rate of 55%, of which 101 (73%) were from practitioners working within the General Dental Services, 20 (14%) from Community Dental Service dentists, and 17 (12%) from practitioners in the hospital dental service. The most popular RBC reported by respondents 43 (31%) was Z100™ (3M UK, Bracknell, UK). The most common factors that influenced respondents’ choice when buying an RBC were ease of use and availability, reported by 51 (37%) and 45 (33%) respondents, respectively. Prime & Bond® (DENTSPLY DeTrey, Konstanz, Germany) was reported as the most popular DBA by 58 (42%) respondents. Overall, availability, reported by 61 (44%) respondents, was the most popular reason for choice of a DBA, followed by ease of use, reported by 52 (38%) respondents, and reliability, reported by 23 (17%) respondents. Conclusions The most popular RBCs and DBAs used by respondents to this study and common reasons for their use were identified. However, it was found that, among those who responded, there was no discernible relationship between undergraduate training, year of qualification and choice of material. Further research is required to corroborate these findings and to identify the level of understanding of material science by dental clinicians.
