Abstract EN
Aims : To evaluate microleakage in Class V restorations, which were restored with flowable composites compared to hybrid composite and to evaluate the difference of microleakage between occlusal and gingival margins.
Materials and methods : Forty five non-carious upper premolar teeth were randomly distributed into 3 groups of 15 teeth each.
Class V preparations were made in the buccal surfaces of each tooth and restored by the use of two flowable composites (Tetric and Megafill) and the third group with hybrid composite (Tetric Ceram).
The specimens were stored in distilled water at 37 °C for 24 hours.
The specimens were then thermocycled manually for 100 times between 5 + 2 °C and 55 + 2 °C.
All restored teeth were immersed in 0.2 % methylene blue dye for 24 hours and sectioned buccolingually with a finishing diamond wheel.
Dye penetration was scored by use of a stereoscopic microscope under magnification of × 20.
Results : The flowable composites had a significant effect on reducing the microleakage at gingival margin (p = 0.01).
The type of material had no significant effect at occlusal margin (p = 0.454).
The occlusal margin had significantly lower microleakage than gingival margin (p = 0.001).
Conclusions : The flowable composites can reduce the microleakage at gingival margins, but non of the restorative materials completely sealed the tooth restoration interface.
