A retrospective, practice-based, clinical evaluation of Fuji IX restorations aged over five years placed in
1Primary Dental Care Research Unit, University of Birmingham, School of Dentistry, St. Chad's Queensway, Birmingham, B4 6NN, UK.
Objective:
To evaluate reinforced glass-ionomer restorations which had been placed in a general dental practice more than five years previously.
Method:
Patients who were identified as having received reinforced one or more reinforced glass-ionomer restorations were invited to attend for an examination of their restorations using scientific evaluation criteria, by one independent examiner and the dentist who owned the practice.
Results:
Forty-two restorations were assessed, their mean age being 7 years and 9 months, in patients of mean age 57 years: 86% achieved an A rating for anatomic form, 69% A for marginal integrity, 81% A for surface roughness and 2% A for colour match.
Conclusions:
The restorations which were assessed were found to be performing satisfactorily at periods of over five years. However, the proportion of the total number of reinforced glass-ionomer restorations placed in the participating dental practice which this represents is not known.
