OBJECTIVE To assess microleakage of enamel-composite and wire-composite interfaces when retainer wires were bonded with two orthodontic and a flowable composites. MATERIALS AND METHODS Forty-five freshly extracted human mandibular canine teeth were used in this study. Teeth were separated into three groups of 15 teeth each. Round stainless-steel wire of 0.36-in. diameter in three groups was b...

conclusions estelite sigma quick composite had wear resistance similar to that of nano- and microfilled composites. estelite flowable composites demonstrated similar wear resistance to that of a posterior composite. results the wear amounts of the composites are as follows in order: estelite sigma quick (1886.9 ± 518.5 μm2), estelite flow quick (2708.9 ± 578.1 μm2), estelite high flow (3206 ± 2...
