Clinical evaluation of hybrid ionomer restoratives in Class V abrasion lesions: Two-year results
Abdalla / Alhadainy
Eighty Class V abrasion cavities were selected, and 20 cavities were restored with one of three resin-modified glass-ionomer materials (Fuji II LC, Photac-Fil, and Vitremer) or a polyacid-modified resin composite (Dyract). The restorations were clinically evaluated after 1 and 2 years with the US Public Health Service criteria. The results revealed a statistically significant difference in the percentage of restorations rated Alfa for color match at 2 years. No statistically significant difference was found in the percentage of alfa rating for anatomic form. Restorations of all materials showed some marginal discrepancies that were not statistically significant.
