Abstract

Purpose: This study examined the recovery of the dentin-resin bonding strength, and the difference in the bonding strength after applying pH hemostatic agents at various pH. Materials and methods: Bosmin, Hemodent, Astregedent, and Visine were used as the hemostatic agents in this study. The Bosmin, Hemodent, and Astrigedent hemostatic agents are acidic, and the Visine hemostatic agent is neutral and is used as a decongestant. Ninety human molar teeth were used as the specimen. The teeth were sectioned using a diamond wheel until the dentin was exposed and wet ground by silica paper. The specimens were divided into two groups according to the hemostatic agent used. The specimens were then subdivided into 9 groups according to the application of re etching (R group) or rinsing only (N group). A commonly used resin bonding procedure was used in the control group. The resin bonding procedure was managed dentin using celluloid capsule. In addition, the shear bond strength was measured using an Instron. Results: In general, samples with the applied hemostatic agent, with the exception of Visine, had a slightly weak bond that was similar to the control group. In addition, the rinsing only (N) group had slightly weak bond that was similar to the re etching (R) group. Conclusion: The application of a hemostatic agent on the dentin surface does not affect the shear bond strength after application for a short time. In addition, rinsing only can recover the shear bond strength making other management procedures redundant, particularly re etching.

목적: 산부식제 적용후 치은 자극으로 인하여 지혈제를 사용할 때 다양한 pH를 가진 지혈제를 적용후 pH에 따른 레진 결합력 차이와 산부식제 재적용 여부에 따른 결합력 회복 정도를 비교하는 것이다. 재료 및 방법: 본 실험에서 사용된 지혈제 중 보스민, 아스트리제덴트, 헤모덴트로 대부분의 지혈제는 산도가 낮다. 또한 바이진은 눈의 충혈제거제로써 성분은 중성이다. 실험방법은 먼저 치관이 건전한 90개의 대구치 10개씩 9그룹으로 나눠 교정용 레진에 식립 한 후 치축과 수직으로 섹션 후 연마한 뒤 대조군은 통상적인 방법으로 산부식과 접착제를 도포 하고, 실험군은 산부식한 뒤 각각의 지혈제를 30초간 오염시킨다. 그 뒤 린스만 한 N 그룹과, 린스 후 산부식제 재적용한 R 그룹으로 나누어서 처치하고 처치한 상아질에 셀룰로이드 캡슐을 이용해 레진 접착을 시행한다. 그리고 인스트론을 이용해 전단력을 측정한다. 통계 분석은 유의수준 0.05 이하로 비교했다. 결과: 대조군과 비교하였을 때, Visine을 제외한 모든 지혈제에서 평균 결합력이 낮아짐을 볼 수 있었으나 통계적으로는 유의할만한 차이는 없었다. 또한 린스만 한 N군과 산부식제 재적용한 R군을 비교했을 때 모든 군에서 결합력 증가가 있었으나 통계적으로는 유의할만한 차이는 없었다. 결론: 임상에서 적용하는 30초의 짧은 적용 시간에는 pH에 따른 지혈제의 영향은 결합력에 영향을 줄 만큼 크지 않고 산부식제 재적용 등 다른 처치를 하지 않아도 린스를 하는 것만으로도 충분히 결합력 회복이 가능하다는 결론을 도출하게 되어 임상과정을 간단하게 하는데 도움이 될 것으로 생각된다.
