Abstract

The purpose of this study was to compare the shear bond strengths of 3-in-1 flowable composite to the enamel and dentin of primary teeth to previous adhesive systems. 110 primary incisors were prepared and divided into two groups: Dentin group included 5 groups: 1) Scotch bond Multi-purpose plus(DSM), 2) Single-bond 2(DSB), 3) Clearfil SE bond(DSE), 4) All bond universal(DAB), 5) Constic(DC), and Enamel group included 6 groups: 1) Scotch bond Multi-purpose plus(ESM), 2) Single bond 2(ESB), 3) Clearfil SE bond(ESE), 4) All bond universal(EAB), 5) Constic(EC), 6) Constic with additional etching(ECE). A cylinder of composite was bonded to the prepared surface, and the shear bond strength was measured. In the dentin groups, group DC had significantly lower shear bond strength than group DSE. No significant difference was found between group DC, group DSM, group DSB and group DAB. In the enamel groups, there was no significant difference between group EC, group ESE, and group EAB. This material showed lowest shear bond strength among all tested materials in both enamel and dentin groups, showing insignificant difference with some adhesive systems. Therefore, 3-in-1 flowable composite can be used for primary teeth restoration but further studies are needed.

이 연구의 목적은 최근 새로 소개된 3-in-1 자가부식, 자가접착 유동성 복합레진의 유치 법랑질과 상아질에 대한 결합력을 기존의 접착 시스템들과 비교 평가하기 위함이다. 110개의 발치된 건전한 유전치를 상아질과 법랑질, 그리고 접착 시스템에 따라 11개의 군으로 나눴다. 연구재료로 Scotchbond Multi-Purpose Plus, Single bond 2, Clearfil SE Bond, All-Bond Universal, Constic을 사용하여 전단결합강도를 평가하였다. 3-in-1 자가부식, 자가접착 유동성 복합레진은 상아질과 법랑질 연구에서 모두 가장 낮은 전단결합강도를 나타냈지만 몇몇 접착 시스템과는 유의한 차이를 나타내지 않아 유치 수복에서 사용될 수 있을 것으로 생각되나 추가적인 연구가 필요할 것으로 여겨진다.
