Although composite and indirect restorations have been used for many years in oral care, clinical studies of the survival rates of restorations placed by general practitioners are lacking. The most important objective of this doctoral research was to investigate the influence of possible risk factors related to practice/operator, patient and tooth/restoration on the longevity of direct restorations. A large database of electronic patient files of general practitioners within the Practice-Based Research Network Nijmegen (PBRN) enabled us to answer these research questions. Practitioners within the PBRN placed restorations with a mean longevity of 12 years, but considerable differences existed among practitioners. Individual patient risk factors such as general health, periodontal status,
risk of bruxism and especially caries risk play a major role in restoration failure. Restorations in molars, restorations with multiple treated surfaces and restorations placed in endodontically treated teeth show greater risk for restorative intervention.
