The Effectiveness RMGI and Giomer, Individually and Combined Anterior Cervical Caries
Sponsor: Cairo University
Summary
This study compares the effectiveness of three dental materials for restoring anterior cervical caries in high-risk patients: resin-modified glass ionomer (RMGI), Giomer, and a combination technique where RMGI is veneered with Giomer. The 18-month randomized clinical trial will assess 75 patients (25 per group), primarily evaluating secondary caries formation, with additional measurements of restoration integrity, appearance, and sensitivity at baseline, 6, 12, and 18 months.

Interventions
Low shrinkage Giomer restorative material (Beautifil II LS)
Enamel margins are etched with 37% phosphoric acid for 15 seconds, then the cavity is bonded using FL bond two-step self-etch adhesive. Giomer is applied in increments (maximum 2mm thickness) and light-cured for 20 seconds with a properly calibrated LED curing light.
RMGI alone - Control
Cavities will be restored with light-cured resin modified glass ionomer (GC Fuji II LC) only. After applying conditioner for 20 seconds, rinsing, and gentle drying, the RMGI will fill the entire cavity and be light-cured
