초록
본 연구의 목적은 브라켓 접착 시 산부식과 전처리 과정을 결합하여 접착 단계를 단순화시킨 self-etching primer (SEP)를 사용하는 경우 접착제 종류와 타액의 존재 유무에 따른 전단결합강도의 차이에 관하여 비교 연구하는 것이다. 소의 하악 영구 전치를 포매하여 만든 시편을 접착제의 종류에 따라 레진 접착제와 레진 강화형 글래스 아이오노머 접착제를 이용한 군으로 나누었고, 각각 37% 인산으로 산부식 후 기존의 본딩용 프라이머를 사용하여 접착한 군과, SEP를 사용하여 접착한 군으로 분류하고, 타액 오염 유무에 따라 다시 각 군을 분류하여 전단결합강도를 측정하였다. 그 결과 레진 접착제로 브라켓을 부착한 경우 SEP를 사용하여 접착한 군의 전단결합강도는 인산 처리군에 비해 낮은데 비해, 레진 강화형 글래스 아이오노머를 사용한 경우, 전처리법에 따른 전단결합강도는 통계적으로 유의한 차가 없었으며, 접착제의 종류에 관계없이 타액 오염이 존재 시에는 SEP를 사용한 군이 인산 처리군에 비해 높은 전단결합강도를 보였다. 이상의 결과에서 SEP를 사용 시 레진 접착제와 레진 강화형 글래스 아이오노머 접착제 모두 임상적으로 사용 가능한 전단결합강도를 보였으며, 특히 타액에 오염된 치면에서도 SEP를 사용하여 브라켓을 접착하는 것은 적절한 결합강도를 얻을 수 있으므로 임상적으로 유용할 것으로 생각된다.
Abstract
The purpose of this study was to evaluate and compare the shear bond strength of orthodontic brackets depending on the variety of adhesives and whether saliva exists, by using self-etching primer (SEP). Groups were divided according to the type of adhesive into resin adhesive (Transbond XT) and resin-modified glass ionomer cement (Fuji Ortho LC). One group of resin adhesive used XT primer after etching with 37% phosphoric acid, and the other group used self-etching primer. One group of resin-modified glass ionomer cement only used etching for bonding, and the other group used SEP. Each of the groups were also classified by whether saliva was contaminated or not, and then the shear bond strength was measured. The results showed that when using resin adhesive, the shear bond strength of SEP was lower than the XT primer. In the resin-modified glass ionomer cement groups, the shear bond strength which depends on the priming method, did not have a meaningful difference statistically. When saliva was contaminated, the group which used SEP, regardless of the adhesive variety, had a greater shear bond strength than the normal priming group. From these results, SEP showed a shear bond strength that is possible to be used clinically, regardless of the adhesive variety. It can especially be clinically useful to use SEP to bond brackets even on tooth surfaces contaminated with saliva, because it offers the appropriate bonding strength as well as shorter treatment time and easy application.
