초록
이 연구의 목적은 근관 내 약제가 규산칼슘 재료의 압출 강도(Push-out bond strength)에 미치는 영향을 평가하는 것이다. 단일 근관을 가진 40개의 인간 하악 소구치들은 대조군과 수산화칼슘, 이중 항생제, 삼중 항생제를 사용한 군 중 하나로 나뉘어졌다. 근관 세척을 통해 약제를 제거 후, 1 mm 두께로 시편들을 제작하였다. 그 후 ProRoot MTA®와 Biodentine®을 근관 내에 적용하였고, 압출 강도 실험과 파절 양상 관찰을 수행하였다. 삼중 항생제와 이중 항생제 군은 대조군과 비교하여 두 종류의 규산칼슘 기반 재료의 상아질 결합력에서 유의한 영향을 미치지 않았고, 수산화칼슘을 사용한 군은 유의한 결합력의 증가를 나타내었다. 대조군과 각각의 실험군 내에서 치근 상아질에 대한Biodentine®의 탈락 저항은 ProRoot MTA®보다 크게 나타났다. 파절 양상에 따라 응집 파절, 혼합 파절, 접착 파절의 순서로 압출 강도의 유의한 감소가 나타났고, 대조군과 비교하여 수산화칼슘을사용한 군에서는 응집 파절이, 항생제를 사용한 군에서는 접착 파절이 우세하였다.
Abstract
The purpose of this study was to evaluate the effect of the intracanal medicaments on the push-out bond strength of the calcium silicate-based materials. Forty extracted single-root human mandibular premolars were sectioned below cementoenamel junction. Standardized root canal dimension was obtained with a parallel post drill. The specimens were randomly divided into a control group (no medicament), and experimental groups received medicaments with either CH (calcium hydroxide), DAP (double antibiotic paste; a mixture of ciprofloxacin and metronidazole), or TAP (triple antibiotic paste; a mixture of minocycline, ciprofloxacin and metronidazole). Following removal of medicaments with irrigation, roots were cut into sections with 1-mm-thickness. Thereafter, calcium silicate-based materials are applied to the specimens : (i) ProRoot MTA® and (ii) Biodentine®. A pushout bond strength was measured and each specimen was examined to evaluate failure mode. Intracanal medication using CH significantly increased the bond strength to the root dentin. But there are no significant differences on the bond strength of ProRoot MTA® or Biodentine® among TAP, DAP and control groups. The dislodgement resistance of Biodentine® from root dentin was significantly higher than that of ProRoot MTA® regardless of the type of intracanal medicaments.
