The cumulative retention rate of a microfilled resin in non-undercut cervical abrasion/erosion lesions was studied over a 5-yr period. The enamel was etched and the dentin was pretreated with either Gluma (n = 75) or the first marketed version of Scotchbond (n = 30). The cumulative 5-yr retention rate of the Gluma fillings was 90% and that of the Scotchbond fillings 47% (the 95% confidence limits were 83-98% for Gluma fillings and 27-67% for Scotchbond fillings). The retention rate with both bonding agents was significantly higher in the maxillary arch than in the mandibular arch.
