Three-year study of cervical erosions restored with resin and dentin-bonding agent.
Cervical erosions without undercuts and traditional cavity preparation were restored with a light-activated microfilled resin in combination with two different dentin-bonding agents, Gluma and the chemically activated version of Scotchbond. In the Gluma group the final polishing was postponed for at least 1 day; in the Scotchbond group polishing was performed 5 to 15 min after polymerization. The results of the two clinical tests are therefore not comparable. Under these experimental conditions the cumulative 3-year survival rate for the fillings in the two groups were 96% (Gluma) and 66% (Scotchbond). It is concluded that cervical erosions should be restored without undercuts or traditional cavity preparation on the condition that the enamel is acid-etched, polishing of the gingival area is postponed, and an effective dentin-bonding agent is used.
