초록

본 연구는 아말감 면에 광중합형 레진으로 교정용 브라켓을 접착시킬 경우, 광원의 차이(할로겐 광중합기와 light-emitting diode (LED) 광중합기)와 샌드블라스팅 표면처리 여부에 따른 접착제의 전단결합강도를 비교하고자 시행되었다. 발거된 소구치 30개를 대조군으로 이용하였으며 법랑질 표면을 산부식한 후 통상적인 방법으로 브라켓을 접착하였다. 60개의 다른 소구치에 아말감 충전을 하여 실험군으로 이용하였다. 두 군에서 할로겐 광중합기와 LED 광중합기를 이용하여 브라켓을 접착시키고 브라켓이 탈락될 때까지 힘을 가해 전단결합강도를 측정하였다. 실험 결과, 실험군의 전단결합강도는 약 3-5.5 MPa로 대조군(19MPa)보다 낮았다. 실험군에서 샌드블라스팅 표면처리를 한 경우, 할로겐 광중합기를 사용한 군이 LED 광중합기를 사용한 군보다 높은 전단결합강도를 보였으나 (P<0.05), 샌드블라스팅 표면처리를 하지 않은 경우에는 광원에 따라 전단결합강도에 차이를 보이지 않았다 (p > 0.05). 할로겐 광중합 군과 LED 광중합 군 모두에서 샌드블라스팅 여부에 따른 전단결합강도에 통계적으로 유의한 차이가 없었다 (p>005). 아말감 면에 광중합형 레진을 이용하여 브라켓을 접착할 경우 할로겐 광중합기와 LED 광중합기로 얻을 수 있는 접착제의 결합강도는 임상적으로 사용하기에는 낮게 나타나, 이의 증진 방법을 도모하기 위해 앞으로 더 많은 연구가 필요하리라 사료된다.

This study was performed to compare the shear bond strength of orthodontic adhesive to amalgam according to different light sources (halogen-based light and light emitting diode (LED)) and amalgam surface treatments. Ninety extracted human premolars were randomly divided into 6 groups (4 experimental and 2 control groups) of 15 by light sources and surface treatments. Orthodontic brackets were bonded and shear bond strength was measured with an Instron universal testing machine. The findings were as follows: The bond strength of adhesive to amalgam surface was 3-5.5 MPa which was lower than that of acid-etched enamel (19 MPa) control. In the sandblasted amalgam surface, the shear bond strength of the halogen light group was higher than that of the LED group (p < 0.05) but. in the non-treated amalgam surface. there was no significant difference in the shear bond strength according to the light sources (p> 0.05). Within the same light source. sandblasting had no significant effect on the shear bond strength of the adhesive bonded to amalgam surface (p > 0.05). There was no significant difference in shear bond strength according to the light sources in acid-etched enamel control groups. This results suggest that there can be a limit in using light curing adhesives when brackets are bonded to an amalgam surface. Additional clinical studies are necessary before routine use of halogen light and LED light curing units can be recommended in bonding brackets to an amalgam surface.
