Sponsored by Dental Practice-Based Research Network · Observational
The purpose of this study was to document the reasons for replacement or repair of defective restorations ("fillings") and to record the restorative material of the failed restoration and the material used in the replacement restoration on permanent ("adult") teeth.
The aims of this study were to (1) quantify the prevalence of reason(s) for replacing existing restorations in DPBRN practices; (2) quantify the percentages and types of restorative materials of failed restorations that are being replaced in DPBRN practices; (3) quantify the percentages and types of restorative materials used to replace or repair failed restorations in DPBRN practices; and (4) test the hypothesis that DPBRN practitioner-investigators who reported in a previous study that they treat enamel lesions operatively are more likely in actual patients as in this study to replace entire restorations rather than do repairs and are more likely to report the clinical diagnosis of secondary caries as a reason for replacement.

Practitioner investigators must have been enrolled in the DPBRN, completed the "Assessment of caries diagnosis \& caries treatment" study; and do at least some restorative dentistry in their practices. The human subjects directly involved in this study were patients who had sought dental treatment in the DPBRN practitoners' practices.
