Clinical evaluation of resin-modified glass-ionomer restorative cements in cervical 'abrasion' lesions: one-year results.
Sixty non-undercut Class V "abrasion" lesions in 13 patients were restored with light-cured Type IIa glass-ionomer cements in accordance with the manufacturer's instructions, 20 each with Fuji II LC, Photac-Fil, and Vitremer. Patients were recalled for examination and photographs 1 week, 6 months, and 1 year posttreatment. Color, marginal discoloration, and retention of the restorations were assessed at each recall period. At 1 year, no loss of restorations was found. Analysis revealed statistically significant darkening in color of the Vitremer restorations, no significant change in color of the Fuji II LC and Photac-Fil restorations, and statistically significant but clinically negligible development of marginal discoloration of all materials.
