Brief Summary

To achieve an optimal contact area is essential to avoid tooth migration, food impaction, and the occurrence of secondary caries. However, proximal restorations constitute challenge for the professional and tight contact points are difficult to obtain depending not only on tools used, but also on type of restorative material. Current tooth-colored restorative materials are not condensable and there is shrinkage with setting. The aim of this study is to compare the proximal contact tightness of zirconia reinforced glass ionomer versus conventional nanohybrid resin composite when used in class II cavities.
