Two-year clinical effectiveness of a resin-modified glass-ionomer adhesive.
OBJECTIVE
To evaluate the clinical effectiveness of a resin-modified glass-ionomer adhesive FujiBond LC (GC) in non-carious Class V cervical lesions.


METHODS
28 patients and 52 abrasion-erosion lesions were restored using FujiBond LC and a microfilled resin composite in a cavity design with the adjacent enamel margins beveled. Clinical parameters as retention, marginal integrity, clinical microleakage, caries recurrence, esthetics, gingival response, tooth vitality and post-operative sensitivity were evaluated at 6 months, 1 and 2 years.


RESULTS
A 100% retention rate was recorded after 2 years of clinical service. However, only 15% of the restorations showed a perfect marginal adaptation. All marginal defects were small, either located at the incisal or at the cervical margin. The percentage of small marginal defects was obviously higher at the incisal enamel margin than at the cervical dentin margin. At the 2-year recall, half of the restorations exhibited a superficial, localized discoloration at the restoration margin, however none of the restorations showed deep, generalized discoloration. Remaining criteria of clinical effectiveness were rated as excellent.
