title: A 24-month follow-up of flowable resin composite as an intermediate layer in non-carious cervical lesions.
abstract: This study compared the clinical performance of a microhybrid resin composite to lined Class V restorations or to those restorations without a flowable resin composite over a 24-month period. Nineteen patients with at least 2 pairs of equivalent cervical erosion/attrition/abfraction lesions, under occlusion, were enrolled in this study. A total of 74 restorations were placed, half for each group (Single-Bond + Filtek-Flow + Filtek Z250 or Single-Bond + Filtek Z250). According to the manufacturers' instructions, 2 calibrated operators placed all restorations. Two other independent examiners evaluated the restorations at baseline and after 24 months, according to the USPHS criteria and modified criteria for color match. The classic alpha score was divided into A1 for "not detectable" and A2 for "slightly discernible" filling. Statistical analysis was conducted using Fisher's exact test (alpha=0.05). For each group, 8 restorations were lost after 24 months (retention rate of 89.2%). All the restorations showed a trend toward dark yellowing after 24 months (color match A2).
