Gingival Marginal Leakage of Different Tooth Colored Materials Combination as an Intermediate Layer in Class II Composite Restoration (A Comparative In Vitro Study)
Main Article Content
Abstract
Materials and methods: Forty maxillary first premolars were prepared with class II box design only cavities. Samples were divided into four groups of ten teeth according to material used: group I (FiltekZ250 only). Group II (SDR+FiltekZ250). Group III (Vertise Flow +FiltekZ250). Group IV (Riva light cure+ FiltekZ250). After 24 hrs. immersion in 2% in methylene blue, samples were sectioned and micro leakage was estimated.
Results: None of the materials showed zero score for dye penetration. Micro leakage percentage in group III had lowest value; followed by group IV then group I while in group II had highest value of micro leakage
Conclusion: All the materials show micro leakage at variable degrees and that the microleakage degree depend on materials type Vertise flow is a promising material to be used in clinic as it saves both time and effort and gives high degree of performance from the microleakage point of view.
