불소 적용 후 교정용 브라켓 접착제 종류에 따른 불소의 재흡수성과 표면의 변화를 비교 평가하고자 하였다. 불소가 방출되지 않은 복합레진 Transbond XT®, 불소 방출성 복합레진 Blugloo®와 LightBond®, 레진강화형 글라스 아이오노머 Rely XTM Luting 2®, 재래형 글라스 아이오노머 FujiI®를 사용하였다. 시편에서 방출되는 불소 방출량을 측정하였고, 불소 재흡수 능력을 비교하기 위해서 시편에 3가지의 불소 제품(APF gel, Tooth Mousse Plus®, Fluor Protector)을 도포하였으며, 불소함유 치약으로 잇솔질을 하여 불소방출량 변화를 측정하였고, 표면조도 측정기와 FE-SEM을이용하여 시편의 표면 조도 및 변화를 비교 평가하였다. Rely XTM Luting 2®와 Fuji I®에서는 다른 불소 제품인 Tooth Mousse Plus®, Fluor Protector뿐만 아니라 불소함유 치약으로 잇솔질한 후에도 불소의 재흡수량을 관찰할 수 있었다. Tooth Mousse Plus®를 도포한 후에는 Transbond XT®를 제외하고 표면 조도 값이 유의하게 증가하였으며, 모든 교정용 접착제에서 부분적인 미세 필러 입자의 탈락을 보였다. Fluor Protector를 도포한 후에는 Transbond XT®, Rely XTM Luting 2®를 제외하고 표면 조도 값이 유의하게 증가하였으며, 모든 교정용 접착제의 표면에 막을 형성하여 기포가 생긴 부분을 제외하고 매끄러운 양상을 나타내었다. 모든 교정용 접착제에 APF gel을 도포했을 때는 표면 조도값이 유의하게 크게 증가하였다. 이상의 결과를 종합해 볼 때, 교정용 브라켓을 접착할 때 치아우식 예방 효과를 도모하기 위한 불소 방출량을 고려한다면 Rely XTM Luting 2®와 Fuji I®가 적극 추천되며, 불소 제품으로는 Tooth Mousse Plus®, Fluor Protector가 APF gel보다 우수한 것으로 나타났고, 불소가 함유된 치약으로 잇솔질을 하였을 때도 치아우식을 예방할 수 있을 것으로 생각된다.
The aim of this study was to compare fluoride release and surface changes according to different orthodontic bracket adhesives the application of fluoride products. We used non-fluoridated composite resin Transbond fluoridated composite resins Blugloo and LightBond, resin-modified glass ionomer Rely XTM Luting 2, and conventional glass ionomer FujiI. Fluoride release of five orthodontic bracket adhesives and fluoride release ability after application of three fluoride products (1.23% acidulated phosphate fluoride gel, Tooth Mousse Plus, Fluor Protector, and a toothbrush with sodium fluoride-containing toothpaste) were measured using a fluoride electrode that was connected to an ion analyzer. After 4 weeks of fluoride application, the surface roughness and surface morphology were examined using a surface roughness tester and field emission scanning electron microscopy. The amounts of fluoride release were observed not only on application of Tooth Mousse Plus and Fluor Protector on resin-modified glass ionomer Rely XTM Luting 2 and FujiI, but also during tooth brushing using fluoride-containing toothpaste. After application of Tooth Mousse Plus, except Transbond XT, the surface roughness increased, and all orthodontic adhesives showed a partial drop of micro-particle filler. On application of 1.23% acidulated phosphate fluoride gel on all orthodontic bracket adhesives, their surface roughness increased. To bond the orthodontic bracket, resin-modified glass ionomer Rely XTM Luting 2 and Fuji I adhesives are highly recommended if the amount of fluoride release is considered to confer a preventative effect on dental caries, and among the fluoride products, Tooth Mousse PlusⓇ and Fluor Protector are better than 1.23% acidulated phosphate fluoride gel, and these are expected to prevent dental caries even during tooth brushing with fluoride-containing toothpaste.
