Aim.
To investigate the effect of C factor on marginal adaptation of low-shrinking composite (Silorane).The null hypothesis was that the marginal adaptation of “Silorane” is not affected by the cavity configuration.
Materials and Methods.
A Silorane based and a methacrylate based composites, with their corresponding self-etch adhesive systems ``Filtek Silorane/Silorane Adhesive Bond System and Filtek Z250/Prompt L-Pop’’ respectively were used.
Standardized cavities were prepared on the buccal surfaces of 100 maxillary premolars.
Teeth were grouped into 5 groups (n = 20), for the 5 C factors.
Restored teeth were subjected to thermocycling.
Microleakage testing was done and linear dye penetration was assessed using a stereomicroscope.
Statistical analysis was done using the Student’s t-test.
Results.
For the methacrylate based systems’ overall leakage score was significantly higher than the Silorane-based one (P = 0.034).
For the methacrylate-based, leakage was found in all tested teeth groups except group 1 (C factor 1/5).
For the Silorane, One-way ANOVA revealed a statistically significant increase in dye penetration in the 5th group (P = 0.010).
Conclusions.
The null hypothesis was rejected.
The Silorane-based resin although it resulted in a statistically significant good marginal adaptation, it showed tendency toward a high leakage score with C-factor of 5.
