The aim of the study was to observe the effect of an additional gingival layer of flowable compomer (Dyract Flow – Detrey Dentsply) on the marginal leakage of class II restoration. Material and method: 20 Class II cavities were prepared in freshly extracted human teeth. 10 cavities were restored using an additional layer of flowable compomer on the gingival floor and 10 cavities were restored using
only Dyract eXtra. The teeth were hydrated for 24 hours and than covered with varnish and immersed in 0,1% methylen blue solution for another 24h. The specimens were cut in mesio-distal slices and the sectioned surfaces were analysed using a stereomicroscope (Neophot 21).
Results: The compomer ability to seal the enamel occlusal margin was good for both groups. The use of the flowable compomer seemed to improve the sealing. However this additional layer did not completely eliminate the marginal leakage at the gingival margin.
Conclusions: Using a thin layer of flowable compomer on the gingival floor of class II restorations could be an adequate method to improve the sealing of the restoration in these areas.
