– Silicate cement specimens have been exposed to infrared radiation for the purpose of improving the erosion resistance. Exposure for periods of 3–10 min, corresponding to a surface temperature of about 60–70°C, resulted in a reduced phosphate release of about 3–5 times that of a non‐exposed group. the temperature distributions on the surface, as well as in a position 5mm beneath the surface, were measured with thermocouples during irradiation. A difference in temprature of about 20°C was registered between the surface and interior positions. the technique may be clinically exploited by exposing the restoration after insertion to a small infrared radiation source, available on the commercial market.
