Clinical evaluation of Scotchbond: three-year results.
In a previous paper, the one-year retention of composite resin in non-undercut Class V abrasion lesions mediated by self-cure Scotchbond dentine bonding agent without enamel etching was reported. The present paper reports the three-year results. Initially, a total of 310 restorations was placed using Silux, Silar, Ketac-Fil and Fuji II. The percentage cumulative loss of the restorations at two and three years, respectively, was: Silux 27, 30; Silar 58, 58; Ketac-Fil 0, 0; Fuji II 4, 14. Over the total study period, there was a high loss rate of composite restorations in the first six months, and a tendency to increased loss over one to three years. There was a significant increase in marginal discoloration, assessed photographically, over the three-year period, and caries was present around some restorations.
