초록

연구목적: 이 연구는 상아질 표면에 Er:YAG 레이저를 조사하지 않는 군, 레이저를 조사한 군, 레이저를 조사한 후 부가적인 산처리를 한 군으로 분류하여 2단계 단일병 전부식 접착시스템과 자가부식 프라이머 접착시스템을 이용하여 복합레진을 접착하였을 때 이러한 표면처리가 복합레진의 미세전단 결합강도와 결합계면에 미치는 영향을 비교하기 위하여 시행하였다. 연구 재료 및 방법: 32개의 발거된 대구치의 교합면측 상아질을 이용하였고, 상아질의 표면처리는 1군과 4군에서 각각 인산과 자가부식 프라이머로 하였으며, 2군과 5군은 Er:YAG 레이저로 에칭처리하였고, 3군과 6군은 레이저로 에칭한 후 다시 각각 인산과 자가부식 프라이머로 하였다. 1군, 2군, 3군은 Single Bond 2와 Z 250 (3M ESPE)을 이용하였고, 4군, 5군, 6군은 Clearfil SE Bond와 Clearfil AP-Z (Kuraray)을 이용하여 상아질 면에 Tygon tube를 접착하였다. 각 군의 미세전단 결합강도를 측정한 후 통계 처리하였고, 또한 6개의 시편에서 복합레진과 상아질 계면을 주사전자현미경하에서 관찰하였다. 결과: Single Bond 2를 사용한 군에서 2군의 결합강도는 1군과 3군보다 통계학적으로 낮게 나타났으며, Clearfil SE Bond를 사용한 군에서 4군, 5군, 6군의 결합강도는 각각 통계학적으로 유의한 차이를 나타내었다(p < 0.05). 2군과 5군은 아주 짧고 가는 레진테그가 관찰되었고, 3군과 6군은 길고 가는 레진테그와 레진테그의 측지가 관찰되었다. 결론: 레이저로 에칭 처리한 상아질에 대한 부가적인 산 처리나 자가부식 프라이머의 처리는 상아질의 접착력을 향상시켰다.

Objectives: The purpose of this study was to compare the microshear bond strength (${\mu}$SBS) and bonding interfaces of two-step total-etching and self-etching adhesive systems to three etch types of dentin either the acid etched, laser etched or laser and acid etched. Materials and Methods: The occlusal dentinal surfaces of thirty human molars were used. They were divided into six groups: group 1, 37% $H_3PO_4$ + Single Bond 2 (3M ESPE); group 2, Er:YAG laser (KEY Laser 3, KaVo) + Single Bond 2; group 3, Er:YAG laser + 37% $H_3PO_4$ + Single Bond 2; group 4, Clearfil SE Primer + Bond (Kuraray); group 5, Er:YAG laser + Clearfil SE Bond; group 6, Er:YAG laser + Clearfil SE Primer + Bond. The samples were subjected to ${\mu}$SBS testing 24 hr after bonding. Also scanning microscopic evaluations were made on the resin-dentin interfaces of six specimens. Results: The ${\mu}$SBS of group 2 was significantly lower than that of groups 1 and 3 in Single Bond 2 (p < 0.05). There were significant differences among the uSBS of groups 4, 5, and 6 in Clearfil SE Bond (p < 0.05). Very short and slender resin tags were observed in groups 2 and 5. Long and slender resin tags and lateral branches of tags were observed in groups 3 and 6. Conclusions: Treatment of dentin surface using phosphoric acid or self-etching primer improved the adhesion of Er:YAG lased dentin.
