CLINICAL-EVALUATION OF TOOTH-COLORED MATERIALS IN CERVICAL LESIONS

Purpose: To determine the 18-month clinical performance of four tooth- colored restoratives in non-carious cervical lesions. Materials and Me thods: Buccal abrasion lesions in 83 teeth were restored with each of the following materials: Fuji Cap II, Fuji II LC, APH/Universal Bond 3 , Lite Fil II A/Imperva Bond. Baseline and an 18-month recall was carr ied out using the Ryge (USPHS) method for retention, color match, marg inal adaptation, cavosurface marginal discoloration, anatomic form and secondary caries. Results: The USPHS results (% alfa) for the four pr oducts were, respectively: color match (9%, 48%, 57%, 55%), marginal d iscoloration (71%, 76%, 52%, 50%), marginal adaptation (24%, 24%, 33%, 15%), anatomic form (67%, 86%, 95%, 45%) and retention (100%, 95%, 10 0%, 65%). Results indicated that (1) Fuji Cap II exhibited a poor colo r match at baseline (2) Color matching of Fuji II LC was comparable to the resin composites and (3) seven Lite Fil II/Imperva Bond restorati ons (35%) were dislodged after 1 1/2 years.
