Assessment of dentists' opinions on the cause of failure of adhesive composite restorations].

Aim of this study was to get an overview of what dentists estimate to be the reason for failure of adhesive composite restorations and to gain knowledge about potential future foci for targeted further education. Therefore, a survey about the fabrication of composite restorations was conducted in the course of seven dental conferences with the main topic tooth-prevention. A total of 577 dentists participated in the survey. The most often called estimated factor for failure of composite restorations was the "dentist" (70.7%), followed by "indication" (32.2%), "material" (8.5%) and "patient" (8.1%). Participants estimated insufficient drying and fluid management (67.9%), incorrect application of the adhesive system (41.8%), insufficient lightpolymerisation (31.2%) and errors in incremental technique (27.6%) to be the main mistakes. The participating dentists claimed to attach great importance to careful drying and fluid management (60.8%), thorough adhesive application (37.3%), adequate incremental technique (32.6%) and sufficient lightpolymerisation (28.8%) while placing their own restorations. According to the survey participants, the treating dentist has the greatest influence on the quality and longevity of composite restorations. Drying and fluid management was the most often called estimated reason for failure but at the same time the step which is given the greatest caution.
