Abstract:

The aim of this study was to compare 24 months clinical performance of two low shrinkage resin composite materials – silorane (Filtek Silorane) composite and methacrylate nano-composite (Filtek Ultimate).

Materials and methods: The clinical study included 37 patients. Total of 56 class II restorations were made. Restorations were observed at baseline, after 6,12,24 months according to United States Public Health System modified criteria. Statistical analysis was performed by SPSS version 17 and a Criterion Pirson (χ2 ) was used to compare the data.

Results: Filtek Silorane and Filtek Ultimate performed statistically similar at two years. All changes observed for marginal staining, marginal adaptation and anatomical form in both studied materials were clinically acceptable.

Conclusions: Although acceptable two years performance of Filtek Silorane, this study did not find any advantages of the silorane based composite over the methacrylate based nano-composite, combined with 3-step total-etch adhesive system.
