Notes:
In this in vitro study the marginal leakage of three composite systems—Sevriton, Consize and Isocap—has been quantified as a function of time.The method used (v.d. Veen et al., 1984) consists of the determination of the amount of nitrogen gas passing through restoration margins at 2 atm.The results show that the marginal leakage of all composites decreased strongly with time and became negligible after about 1 month. If we rank the three systems investigated according to their marginal leakage we have Consize〉Isocap〉Sevriton. The data suggest that water uptake and subsequent expansion of the polymers account for the leakage decrease.
