Effect of the 457 ㎚ Laser on the Bond Strength of Orthodontic Brackets

Mi-Gyoung Park; Yong Hoon Kwon

본 연구는 457 ㎚ 레이저가 교정용 브라켓의 전단결합강도에 미치는 영향을 평가하였다. 본 연구에서는 3종의 수복용 복합레진(Filtek Z350, Filtek Z250 및 Filtek Z350 flow)과 Transbond XT를 접착제로 사용하였고, 457 ㎚ 레이저 (LVI-VA457-100)와 2종의 광조사기 (Optilux 501, L.E.Demetron)를 사용하였다. 교정용 브라켓을 발거된 상악소구치에 부착하고 광조사한 후, 광중합이 완료된 시료의 결합강도를 측정하고 파절면을 관찰하였다. 그 결과 광조사기군에서는 통계적으로 유의한 차이는 나타나지 않았다. 반면, 접착제군에서는 통계적으로 유의한 차이가 나타났으며, Transbond XT군이 (14.17 ± 2.53-16.56 ± 2.89 ㎫) 다른 복합레진군보다(13.04 ± 1.68-14.59 ± 2.89 ㎫) 높은 결합강도를 보였다. 시편의 반 정도는 (42%-LED, 42%-QTH, 및 52%-457 ㎚ laser) 치아-접착제 계면 파절을 보였으며, 나머지 반을 접착제 내에서 파절이 발생하였다. 결론적으로 457 ㎚ 레이저는 QTH (Optilux 501)나 LED (L.E.Demetron) 광조사기와 마찬가지로 교정용 브라켓을 부착 시 광조사기로 사용될 수 있다는 것을 확인하였다.
