Clinical Evaluation of Silorane-based Resin Composites in the Posterior Teeth: An 18 Months Follow-up Study

The silorane-based resin composites have low polymerization shrinkage and stress, good stability in aqueous environments and insolubility in biological fluid stimulants compared with conventional dimethacrylate based composites. The aim of this study was to clinically evaluate the performance of silorane-based resin over a period of 18 months. The study was conducted in ten posterior restorations performed with silorane. Clinical evaluations were done periodically to evaluate the success of the restorations using predefined criteria. Eight out of ten restorations fulfilled all criteria up to 18 months. Two restorations had marginal chipping of the composite material. From this short-term clinical study, it can be concluded that siloranes can be used as an alternative to other posterior restorative composites. Further research over longer periods with larger samples are required to substantiate the current observations.
