title: Clinical evaluation of direct esthetic restorations in cervical abrasion/erosion lesions: one-year results.
abstract: One hundred sixteen cervical abrasion/erosion lesions were restored with one of the following techniques: (1) glass-ionomer cement, (2) composite resin with a dentinal bonding agent, or (3) composite resin with a glass-ionomer cement liner and a dentinal bonding agent. The restorations were assessed at baseline and at 6 months and 1 year postrestoration for retention, caries, color match, marginal staining, and surface texture. No statistically significant differences were found in retention, caries, color match, or marginal staining. A statistically significant difference was found with regard to surface texture: glass-ionomer cement restorations demonstrated a rougher surface than did the composite resin restorations. A substantial number of restorations composed of composite resin with a dentinal bonding agent demonstrated a color shift towards mismatch when evaluated at 6 months. This difference was not significant at the 1-year followup.
