EFFECT OF LIGHT-EXPOSURE DURATION ON THE AMOUNT OF LEACHABLE MONOMERSFROM LIGHT-ACTIVATED RELINE MATERIAL

Leaching of monomers from light-activated direct intraoral reline mate rial (Lebaron LC) was determined by means of high-pressure liquid chro matography analysis, This study evaluated the effects of exposure dura tion and thickness to determine appropriate curing conditions that red uce the levels of unreacted monomeric components, Prolonged duration o f exposure (30 minutes) reduced the amount of leached monomer, However , the results of this study indicated that the amount of leached monom eric components increased with an increasing reline material thickness , The results suggest that the light-activated reline material should be cured for sufficient prolonged exposure duration.
