1-year clinical evaluation of one-step in non-carious cervical lesions.
OBJECTIVE
To evaluate the 1-year clinical retention rate of restorations of non-carious cervical lesions placed using a "one-bottle" adhesive (One-Step) and one of two low modulus resin-based composite (RBC) restorative materials (AEliteflo or Bisco Glaze) or a microfilled RBC (Silux Plus).


METHODS
105 non-carious cervical lesions in 14 patients, mean age 60 years, were restored using either AEliteflo, Bisco Glaze or Silux Plus with One-Step dentin bonding agent. The dentin surface was lightly roughened with a fine diamond stone, cleaned with pumice and water and restored according to the manufacturers' instructions. Patients were recalled at 6 months and 1 year, and the restoration sites examined.


RESULTS
At 6 months all restorations were present. At 1 year, five restorations were missing (two Silux, three AEliteflo), three of which were in one patient. A cumulative retention rate of 95% was recorded. A small number of restorations exhibited marginal discoloration, but this was believed to be due to excess RBC on unetched enamel.
