The aim of this study was to evaluate changes in decalcification resistance of glass ionomer containing α-TCP. Total forty cavities were prepared form extracted bovine teeth and were divided into four groups of ten each in order to evaluate decalcification resistance. The cavities of each groups were restored with glassionomer cement containing 0 %(Group1), 5 %(Group2), 15 %(Group3) and 25 %(Group4) α-TCP. After half of each specimen were treated with varnish, there were immersed in a decalcifying solution for 96 hours at 37 ℃. The mineral loss of specimens were measured by fluorescence loss values using a QLF-D. In addition, compressive strength were measured according to ISO 9917-1. According to the results, loss of fluorescence(△F, %) was ?5.91 in group 1, ?5.88 in group 2, ?5.82 in group 3, ?6.06 in group 4 (p>0.05). loss of minerals(△Q, %, ㎜²) was ?245.72 in group1, ?146.40 in group2, ?143.50 in group3, ?251.98 in group4(p>0.05). Decalcified area(area, ㎜²) was 40.75(35.3) in group1, 24.05(48.13) in group2, 23.9(22.02) in group3, 28.28(58.41) in group4(p>0.05). Loss of fluorescence, loss of minerals and decalcified area of group2 and group3 were lower than group1 and 4. But there were no significant difference among groups. Compressive strength(MPa) was 148.99 in group1, 121.12 in group2, 62.59 in group3, 19.38 in group4, decreased statistically significant(p＜0.05). Although there were no significant difference to resistance of decalcification, it was showed that resistance of decalcification of glass ionomer cement containing 5 % and 15 % of α-TCP were lower than glass ionomer cement.
