    [Abstract]ObjectiveTo explore better materials and methods for restoring deep dental wedge-shaped defects. Methods486 teeth in 189 cases with wedge-shaped defects were randomly divided into three groups which were restored with glass inomer cement restoration, light-cured composite resin restoration and the sandwich technique respectively. Evaluation was made after restoration for 1 to 2 years respectively. ResultsThe successful rates of glass inomer cement restoration, light-cured composite resin restoration and the sandwich technique after 1 to 2 years were 89.66%, 84.72%, 93.46% and 69.17%, 82.22%, 90.28% respectively. The successful rate of the sandwich technique group was higher than that of the other two groups. ConclusionThe clinical curative effect of the sandwich technique for restoring deep dental wedge-shaped defects was better. ......
