Three-year evaluation of effect of surface conditioning on bonding of glass ionomer cement in cervical abrasion lesions.
Cervical abrasion/erosion lesions were restored without any form of mechanical cavity preparation with an anhydrous glass ionomer cement. To study the effect of dentin pretreatment on the bonding between dentin and glass ionomer cement three cleaning methods were tested: 1) mechanical cleaning with a prophylaxis paste, 2) scrubbing with a surface active cavity cleanser (Tubulicid) for 60 seconds, or 3) a 10-15 s application of a 40% polyacrylic acid solution. During a 3-yr period, 193 restorations were evaluated every 6 months. Cumulative loss rates after 3 yr were 11.6%, 12.3%, and 17.9% respectively. One restoration showed secondary caries during the evaluation period.
