The aim of this study was to evaluate the elution substances from different materials used for manufacturing temporary indirect restorations, after storage in saliva and ethanol 75%. 10 samples three chemically cured (Protemp 3 Garant, Systemp.c&amp;b, Trim) one light-cured material (Clip F) were stored 75% 24 h, 7, days 28 days. From media at each time period, prepared analysed by LC-MS/MS, order access monomers. results differed among (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mi>P</mml:mi></mml:mrow></mml:math>≤ 0.05). No monomers detected Protemp Garant Clip F. Substances only Systemp.c&amp;b Trim. amount BisGMA, TEGDMA, UDMA 2 released higher compared Storage affected release id="M2"><mml:mrow><mml:mi>P</mml:mi></mml:mrow></mml:math>≤ highest observed within first h. It can be concluded that provisional resin composite do not show high is dependent. However, detection additional peaks during analysis, suggesting formation by-products eluted substances, may favour these with respect their toxicity.
