Abstract
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.
