Clinical Evaluation of a Restorative Glass Ionomer and a Bulk-fill Composite Resin

December 2, 2025 updated by: Dr. Fatma Dilşad Öz, Hacettepe University
The clinical performance of a restorative glass ionomer and bulk-fill resin composite in class II restorations will be evaluated and compared. After recruiting participants with at least 2 approximal caries lesions, all restorations will be placed by a single clinician. All caries lesions will be removed before restoring. Cavities will be divided into two groups: a restorative glass ionomer [Equia Forte HT, GC, Tokyo, Japan (EHT)] and bulk-fill composite resin [SonicFill2, Orange, CA, USA (SBF)] All restorative procedures will be conducted according to manufacturers' instructions. Restorations will be scored using modified United States Public Health Service (USPHS) criteria after a week (baseline) 6, 12, 24, 36 and 48 months. Descriptive statistics will be performed using chi-square tests.
