[{'content': 'Advantage of using chemically activated resin for repairing is: \nSelect and explain. \nA. They can be polymerized at room temperature, B. They are easy to manipulate, C. Easy to handle, D. Cheap in cost', 'role': 'user'}, {'content': 'Answer: A \nExplanation: ADVANTAGES AND DISADVANTAGES\n\nBetter initial fit, which is because the curing is carried out at room temperature. Thus\xa0there is less thermal contraction.\nColor stability is inferior to that of heat cure resin, due to subsequent oxidation of the\xa0tertiary amine.\nSlightly inferior properties because the degree of polymerization of self curing acrylics\xa0is less than that of heat cured ones.\nFor repairing dentures, self curing resins are preferable to heat cured resins as heat curing\xa0causes warpage.', 'role': 'assistant'}]
