Summary

Brief Summary: Retrospective study to evaluate the clinical performance of two restorative materials - glass-ionomer (GI) and resin-modified glass-ionomer (RMGI) materials - in Class V carious and non-carious cervical lesions restored by dental students.

Detailed description

The aim of this retrospective study was to evaluate the clinical performance of glass-ionomer (GI) and resin-modified glass-ionomer (RMGI) materials in Class V carious and non-carious cervical lesions restored by dental students. Ninety-six (96) restorations performed with either GI (Fuji IX) (n=39) or RMGI (Fuji II) (n=57) were evaluated using the modified USPHS (United States Public Health Systems) criteria by two independent investigators at two follow-up evaluations (two years apart). The Fisher statistical test was used to compare USPHS criteria and examine significant differences by setting p\<0.05 for statistical significance and the Kaplan-Meier algorithm was used to calculate the survival probability.
