Abstract

The aim of this study was to evaluate the shear bond strength (SBS) of three typical restorative materials - glass ionomer cement (GIC), resin-modified glass ionomer (RMGIC) and composite resin (CR) - to different pulp capping materials, i.e., Theracal $LC^{TM}$ (TLC), $Biodentine^{TM}$ (BD), and $ProRoot^{TM}$ white MTA (WMTA). 90 acrylic blocks with a center hole were prepared. The holes were completely filled with three pulp capping materials (TLC, BD, and WMTA), with 30 specimens per capping material. The samples were then randomly divided into 3 subgroups of 10 specimens each and were overlaid with GIC, RMGIC, or CR. A total 9 specimen groups were prepared. The SBS was assessed using a universal testing machine. Kruskal-Wallis test and Mann-Whitney's test were performed to compare the SBS among the subgroups (p < 0.05). After the SBS test, the fractured surfaces were examined under a stereomicroscope at a magnification of $25{\times}$. The highest and lowest SBS values were recorded for TLC-CR and TLC-GIC, respectively. With regard to the SBS to the three pulp capping materials, CR was found to be superior to RMGIC and GIC. BD showed a higher SBS compared to TLC and WMTA when used with GIC.

본 연구의 목적은 Tricalcium silicate를 기반으로 한 3종의 치수복조재(Theracal $LC^{TM}$, $Biodentine^{TM}$, $ProRoot^{TM}$ white MTA)와 임상에서 통상적으로 사용되는 수복재인 복합레진, 레진강화형 글래스아이오노머 시멘트, 그리고 전통적인 글래스아이오노머 시멘트 간의 전단결합강도를 비교 평가하는 것이다. 이를 위해 중심구를 가진 아크릴 레진 블록 90개를 제작하고 각각 30개씩 3종의 치수복조재로 중심구 안에 채운 다음, 다시 무작위로 10개씩 하위 군을 나누어 치수복조재 상방에 복합레진, 레진강화형 글래스아이오노머 시멘트, 전통적인 글래스아이오노머 시멘트를 적용하여 총 9개 군으로 이루어진 시편을 제작하였다. Universal testing machine을 이용해 전단결합강도를 측정한 뒤, 입체현미경을 사용해 파절양상을 분석하였다. 연구 결과, Theracal $LC^{TM}$-복합레진 군이 가장 높은 전단결합강도를, Theracal $LC^{TM}$-전통적인 글래스아이오노머 시멘트 군이 가장 낮은 전단결합강도를 나타냈다. 복합레진이 수복재로 선택된 군들이 다른 수복재 군에 비해 높은 전단결합강도를 보였다. 전통적인 글래스아이오노머 시멘트가 수복재인 경우 $Biodentine^{TM}$이 다른 치수복 조재 군들에 비해 높은 전단결합강도를 나타냈다.
