Objective To explore clinical efficacy of sandwich technique in the treatment of deep dental wedge-shaped defects .[Methods]Totally 86 patients(302 teeth) with deep dental wedge-shaped defects were chosen .Ac-cording to patients'will ,all patients were divided into two groups .The observation group( n=43 ,152 teeth) was treated with sandwich technique ,while the control group( n=43 ,150 teeth) were treated with glass ionomer ce-ment .The successful rate was compared between two groups .[Results]The successful rate of observation group after 6 months was 97 .36% ,which was obviously higher than that in control group (88 .67% )( P <0 .05) .The successful rate of observation group after 1 year was 90 .79% ,which was obviously higher than that in control group(79 .33% )( P <0 .05) .[Conclusion] Sandwich technique is easy to operate ,and has certain efficacy in the reparation of deep wedge-shaped defect ,and can prevent the secondary caries and restore the shape and beauty of the diseased teeth .Therefore ,it is worthy of clinical promotion .
