Objective: This study evaluated the in-service performance, after 1 year, of a sample of F2000 compomer restorations placed by 10 general dental practitioners as part of handling evaluation of this material. Method and materials: Five general dental practitioners who participated in the handling evaluation were asked to cooperate in the 1-year assessment of the restorations. The practitioners were requested to contact patients and inquire if they were willing to attend at a specified time for examination of their restorations by a trained evaluator who would travel to the various practice locations. A total of 84 restorations were presented for examination. The mean age of the restorations at examination was 14 months. The restorations were assessed for anatomic form, marginal adaptation, surface roughness, sensitivity or discomfort, gingival condition, and presence or absence of secondary caries. Results: Eighty-two restorations were intact. No secondary caries was detected. Optimal scores were obtained in a high proportion of the assessments. All patients reported satisfaction with the restorations, both in appearance and surface texture, and no symptoms were reported. Conclusion: The F2000 compomer restorations, placed in conjunction with its bonding system in general practice conditions, were found to be performing satisfactorily after 1 year.
