Abstract

Objectives: The aims of the present study were to assess the reasons for the placement and replacement of resin-based composite (RBC) restorations in permanent teeth and to establish the longevity of replaced restorations. Methods: The study population consisted of 2,480 individuals attending a private practice. Clinical examination involved the evaluation of the numbers of decayed teeth (primary caries) and failed restorations, respectively, and the reasons for the placement and replacement of RBC restorations. In addition, possible associations between the placement and replacement of restorations and type of cavity, and the reasons for the placement and replacement of RBC restorations by tooth type were assessed. Statistical analysis was accomplished using the chi-squared test. Results: A total of 3,528 restorations were identified; 2,046 (58%) of these were first-time restorations and 1,482 (42%) were replacement restorations. The main reason for first-time RBC restorations was primary caries (56%). Secondary caries was the most frequent reason for the replacement of RBC restorations (43%). Statistically significant differences were recorded between cavity type and first-time (P = 0.0083) and replacement (P = 0.0067) restorations. No statistically significant differences were observed between tooth type and the reasons for first-time (P = 0.067) or replacement (P = 0.073) RBC restorations. The median longevity of replaced restorations was approximately 4 years (39%). Conclusions: Primary and secondary dental caries were the principle reasons for first-time and replacement restorations, followed by tooth and restoration discolouration, respectively. Therefore, patients at high risk for developing caries may require more frequent dental care. © 2012 FDI World Dental Federation.
