Abstract：
:One hundred cervical caries-free, nonundercut lesions were restored in 13 patients of mean age 60.5 years, using Silux Plus or Estio LC resin composite bonded with Fuji Bond LC. Patients were recalled at 6 months and 1 year. A 1-year cumulative retention rate of 98% was recorded, while marginal staining was absent.
