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% an A rating for marginal integrity, 81% an A for surface roughness and 2% an 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.
