Selected and simplified FDI criteria for assessment of restorations


Objectives Assess the quality of dental restorations with simplified FDI criteria and examine its relationships with other general characteristics of restored teeth. Methods The study involved 76 dentists from private and hospital practices. Assessments of successes and failures of previous restorations used a simplified rating with FDI criteria 3 to 8, 11, 12, and 14. The results were examined versus tooth location, number of restored surfaces, type of restoration, and filling material. Results The dentists examined 4,612 dental restorations, of which 4,185 direct fillings mainly with resin composite materials (2,555). Of all restorations, 2,048 (44.4%) were considered as failures, of which 1,489 had one or two criteria for ‘clinically unsatisfactory/poor restoration’. As simplified, the esthetic criterion ‘color match’ was the most frequent criterion for failure (912 cases). The rate of restoration failures was found associated with the number of surfaces restored and the use of glass-ionomer cement. Results are not comparable with others obtained with original FDI criteria. Conclusions Assessing dental restorations with the original FDI criteria leads generally to much more failure statements than practitioners’ decisions to reintervene. Though requiring some adjustment (e.g., regarding ‘color match’), the simplified assessment proved convenient and amenable to standardization. Clinical Significance Regardless of the type of practice, selecting, understanding, and optimal interpreting of FDI criteria for failure is essential to help practitioners faced with daily dilemmas of replacement vs. repair of failed dental restorations. Standardization of simplified criteria is desirable to help comparing research data.
