Article Synopsis
- The project aimed to investigate how different fatigue loading methods (contact vs. flexure) impact the flexure strength of a dental composite called Restolux.
- The study involved creating small composite bars and testing them under varying cyclic loading conditions in different media over a period of four months.
- Results showed that flexure loading significantly weakened the composite due to aging media, while contact loading strength decreased mainly with the number of cycles completed.

The objective of this study was to determine the leaching of Ba, Si, and Sr from four dental composites: Restolux (RX), Micronew (M), Renew (RW), and Choice (C) and to correlate the effects of such leaching with flexure strength and modulus of elasticity. The specimens were 3 x 3 x 25-mm bars, polished with 120- and 240-grit SiC paper, and were aged for 4, 6, and 8 months in artificial saliva, distilled water, and a 50/50 mixture of ethanol and distilled water. Inductively coupled plasma with mass spectroscopy (ICP/MS) was used to determine the ion concentrations after aging.
