Abstract
본 연구는 상아질 접착제와 레진 시멘트의 적합성 여부를 알아보고자 시행하였다. 발거한 제3대구치의 상아질 표면을 노출시킨 후 Tescera ATL 복합레진 시편을 상아질 접착제 [All Bond 2 (Bisco), Clearfil SE Bond (Kuraray), Adper Prompt L-POP (3M), One-Up Bond F (Tokuyama)]와 레진시멘트 [Choice (Bisco), Panavia F (Kuraray), RelyX ARC (3M), Bistite II DC (Tokuyama)]로 접착하고 미세인장 결합강도 및 주사전자 현미경 관찰을 시행한 결론은 다음과 같다. 1. Clearfil SE Bond와 All-Bond 2가 Prompt L-Pop과 One-Up Bond F 보다 높은 미세인장 결합강도를 보였다(p<0.05). 2. Clearfil SE Bond와 All-Bond 2 사용시 1-step 상아질 접착제보다 혼성층이 두껍고 레진 tag가 길었다.
This study was performed to investigate the compatibility between 4 dentin adhesives and 4 resin luting cements. Dentin adhesives used in this study were All-Bond 2 (Bisco Inc., Schaumbrug, IL, USA), Clearfil SE-Bond (Kuraray Medical Inc, Osaka, Japan), Prompt L-Pop (3M Dental Products, St. Paul, MN, USA), One-Up Bond F (Tokuyama corp., Tokyo, Japan) Resin luting cements used in this study were Choice (Bisco Inc., Schaumbrug, IL, USA), Panavia F (Kuraray Medical Inc, Osaka, Japan), RelyX ARC (3M Dental Products, St. Paul, MN, USA) Bistite II DC (Tokuyama corp., Tokyo, Japan). Combination of each dentin adhesive and corresponding resin cement was made to 16 experimental groups. Flat dentin surfaces was created on mid-coronal dentin of extracted mandibular third molars, then dentin surface was polished with 320-grit silicon carbide abrasive papers. Indirect resin composite block (Tescera, Bisco) was fabricated. Its surface for bonding to tooth was polished with silicon carbide abrasive papers Each dentin adhesive was treated on tooth surface and resin composite overlay were luted with each resin cement. Each bonded specimen was poured in epoxy resin and sectioned occluso-gingivally into 1.0mm thick slab, then further sectioned into $1.0{\times}1.0mm^2$ composite-dentin beams. Microtensile bond strength was tested at a crosshead speed of 1.0mm/min. The data were analysed by one-way ANOVA and Duncan’’s multiple comparison tests The results of this study were as follows, 2-step self-etching dentin adhesive which has additional bonding resin is more comparison than tests. self-etching dentin adhesive.
