摘要: summary This study evaluated fracture resistance in class II slot packable composite restorations with and without the use of a flowable liner. A conventional microhybrid was used as control. Thirty-six sound, caries-free human mandibulary molar teeth were used. Separate mesio-occlusal disto-occlusal cavity preparations made each tooth. The prepared randomly divided into three groups 12 teeth. Two composites (Surefil, Filtek P60) one (Filtek Z250) their respective manufacturer's bonding agents to restore cavities. One side tooth restored alone, while other lined that marginal ridges loaded at an angle 13·5° long-axis Instron Testing Machine until failure. data analysed using one-way anova. There no significant difference between liners.
