Abstract

Aim of the study: This study was directed to evaluate the microleakage of different types of composite resin in class II posterior restoration at the cement-enamel junction CEJ. Materials and methods: Eighty one freshly extracted molars were selected. The teeth were divided into three main groups (27 each) according to the material used. Group 1: samples were restored with packable resin composite. Group 2: samples were restored with packable resin com­posite lined with 1-1.5mm layer of flowable resin composite. Group 3: samples were restored with hybrid resin composite. Each group was divided into three subgroups (9 each) according to the storage time. Subgroup A, B and C: storage time was 24 hours, 1 month and 3 months respectively. The gingival margin was located at the CEJ. The teeth were restored and microleakage testing was performed using dye penetration method. The data were collected and statistically analyzed. Results: The packable composite group recorded the highest microleakage values followed by hybrid composite group then flowable-lined packable composite group and this was statistically with high significance (p<0.001). The three groups showed the least microleakage values after one month followed by three months storage while the highest values were after 24 hours storage. Conclusion: None of the tested materials was able to completely eliminate marginal micro­leakage at CEJ but the use of flowable resin composite as a liner under packable resin composite showed a reduction in microleakage compared to the other types.
