Effect of exposure time on the LED lamp irradiation on the mechanical properties of dental fillings
A corm dental composite was irradiated for 10-70 s to study the curing efficiency. Compressive strength, Young modulus and compression strain of the composite were detd. Organoleptic appearance of cracks in the composite was also obsd. The compression strain decreased during the irradn. but compression strength and Young modulus reached a max. after irradn. for 30 s and 20 s., resp.
