Clinical evaluation of a flowable resin composite in non-carious Class V lesions: two-year results

This in vivo study evaluated the clinical performance and appearance of a flowable resin composite and a hybrid resin composite over two years. Twenty-eight (28) pairs of restorations of a flowable resin composite and a conventional hybrid resin composite were placed in non-carious, asymptomatic facial Class V lesions. The restorations were evaluated at baseline, six, twelve, eighteen and twenty-four (6, 12, 18 and 24) months, using modified Ryge/USPHS criteria. No significant difference (p < 0.05) was observed in the performance or appearance of both materials.
