Effect of Radii barrier sleeves on cure depth of composite resin / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To explore the effect of Radii barrier sleeves on the cure depth of composite resin.@*METHODS@#Cylinder mold was prepared, and the resin was filled strictly into the mold. The surface was flattened and then cured with plastic engraver's knife.The depth of composite resin which was cured by QHL75TM with or without Radii barrier sleeves was compared.@*RESULTS@#The cure depth of composite resin which were cured by QHL75TM with or without Radii barrier sleeves of photo-curing machine was 4.38 mm and 4.27 mm respectively,with no statistical difference.@*CONCLUSION@#The cure depth of composite resin is not influenced by Radii barrier sleeves under the same light condition.
