Abstract

The purpose of this study was to compare the light transmitting ability of halogen light in different colors and thicknesses. A1, A2, A3 colors of Z-250 composite resin(3M ESPE, St. Paul, U.S.A.) were used. Degree of conversion of separated resin specimens under the 2, 3, 4mm thickness resin were measured by FTIR spectroscopy. The result shows that decrease of degree of conversion by increase of resin thickness and decrease of degree of conversion by decrease of lightness of color. Within the limitation of results, it is recommended to use more light color of composite resin in small thickness to improve degree of conversion when use halogen light.

본 연구에서는 할로겐 광원의 빛이 복합레진의 색상과 두께에 따라 어느 정도 투과가 되는지를 비교하고자 Z-250 복합레진 (3M ESPE, St. Paul, U.S.A.)의 A1, A2, A3 색상에서 2, 3, 4 mm 로 두께를 달리한 뒤 밑면에서 복합레진 본체와 차단된 복합레진 시편의 중합도를 FTIR spectroscopy로 측정하였다. 그 결과 색상이 어두워질수록 할로겐 광원의 투과능력은 감소하였으며 두께가 두꺼워질수록 할로겐 광원의 투과능력이 감소하였다. 위의 결과를 바탕으로 할로겐 광원을 이용하는 중합도를 향상시키기 위해서는 복합레진의 색상을 밝은 것으로 이용하며 가급적 얇은 두께로 복합레진을 충전하여야 할 것으로 사료된다.
