Restorations of primary molars with conventional glass ionomer cement showed increased risk of failure than compomer , resin-modified glass ionomer cement , amalgam , and composite resin .
This study aim ed to compare the longevity of different conventional restorative material s placed in posterior primary teeth .
Conservative interproximal box-only polyacid modified composite restorations in primary molars, twelve-month clinical results.
The treatment of proximal caries has changed during the last decade . The present study evaluates a recently developed material , applied in box-only preparations in primary molars . At the twelve-month evaluation of this clinical study , it became obvious that Dyract can be an alternative for Tytin in the primary dentition , though there is some change in color of the Dyract material . In time , the marginal adaptation of Dyract  seems to improve . The preparation time for both material s is comparable . The total treatment time of box-only Dyract restorations ( including an occlusal sealant ) , however , is longer compared to conventional class II Tytin restorations . Although in both groups radiolucencies were found at the baseline radiograph evaluation , no sign was found of secondary caries . One recurrent caries lesion was found adjacent to a Dyract restoration . It should be emphasized that one-year data do not indicate the longterm success of restorations
