AbstractAims: Evaluate the ability of different a bulk-fill flowable composite sealing around class I cavities compared to conventional composite. Materials and Method: Forty upper premolar teeth prepared with an ideal class I, then distributed according to types of composite resin into four groups (n=10): group I= filling with SDR, group II= filling with Sarmco flowable composite resin, group III= filling with Tg flowable composite resin, finally group IV= filling with Valux plus composite resin (as a control) polymerized by LED light cure unit, varnished and placed in 2% methylene blue then sectioned bucco-palatally. The Micro-leakage was determined by stereomicroscope. Results: There was a significant difference (p<0.05) in mean micro-leakage values between SDR (group I) and Saremco (group II) while there was no significant difference (p>0.05) in micro-leakage values between SDR (group I) and Tg (group III) and Valux plus (group IV). Conclusion: SDR can be applied in 4 mm as a lone layer without negative effect on micro-leakage.
