초록
본 연구는 각각 다른 농도의 황산리튬을 함유한 폴리아크릴산을 적용시간을 변화시켜 치아의 법랑질 표면에 도포하여 크리스탈을 형성하고 그 위에 도제브라켓을 부착한후 전단결합강도와 파절양상을 비교하기 위하여 시행하였다. 농도가 서로다른 흔합용액 4종류를 교정치료를 위해 발거된 건전한 소구치 48개의 법랑질 표면에 적용시켰다. 실험용액들은
The purpose of this study was to compare shear bonding strengths and debonding patterns of the ceramic brackets attached on the crystal which were grown on the enamel surface of a tooth with different concentrations of lithium sulphate-contained polyacrylic acid in different application times. Four kinds of concentrations of mixed solutions were made and applied to the enamel surface on extracted human premolars. The solutions were made by adding 0.3M or 0.6M of lithium sulfate to
