Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
