초록

복합레진 수복시, 일반적으로 연마, 산부식, 수세 및 건조 단계를 거쳐 저점도 레진을 적용하는 재접착 술식을 통해 예상되는수축간극을 봉쇄한다. 그러나, 이 과정은 재접착제 적용 이전에 물이나 잔사가 간극을 매워버릴 수 있어 그 효과가 의심된다. 본 실험에서는 연마 단계 이전, 즉 복합레진을 중합한 직후에 재접착제를 도포한다면 변연누출을 더 줄일 수 있을 것이라는 가설을 검증하고자 하였다. 실험을 위해 35개의 발거한 대구치에서 협면과 설면에 교합면 변연은 법랑질에, 치은측 변연은 상아질에 위치하는 5급 와동을 형성하였다. 와동은 Z250 (3M ESPE, USA)로 충전하였고, 접착제로는 AdperTM Single Bond 2(3M ESPE)을 사용하였다. 재접착제로는 Biscover LV (Bisco, USA) 레진 전색제와 ScotchBond Multi-purpose system (3M ESPE)의 접착제, 및 점도가 낮은 실험용 접착제를 연마 전 또는 일련의 연마 및 산부식 후 수복물의 변연에 적용하였다. 2% 메틸렌 블루 용액에 네 시간 동안 침적한 뒤 교합측 및 치은측 변연에서의 색소 침투 깊이를 광학 입체 현미경으로 측정하였다. 재접착제의 점도와 변연미세누출의 상관관계도 평가하였다. 재접착 술식, 재접착제, 및 변연의 위치, 그 각각에서는 통계적으로 유의한 차이를 관찰할 수 없었다. 그러나, 재접착 술식을 시행하지 않은 대조군의 경우에는 세 가지 재접착제를 사용한재접착군에 비해 치은측 변연에서 미세누출이 통계적으로 유의하게 크게 나타났다(p < 0.05). 대조군과 재접착군의 미세누출의 차이는 교합측 변연에서는 관찰되지 않았다. 연마 및 산부식 후 치은변연에 재접착제를 적용한 경우에서 약한 음의 상관관계(r = -0.326, p = 0.041)를 보인 경우를 제외하고는, 재접착제의 점도와 미세누출은 유의한 상관관계를 보이지 않았다.

Abstract

During a composite resin restoration, an anticipating contraction gap is usually tried to seal with low-viscosity resin after successive polishing, etching, rinsing and drying steps, which as a whole is called rebonding procedure. However, the gap might already have been filled with water or debris before applying the sealing resin. We hypothesized that microleakage would decrease if the rebonding agent was applied before the polishing step, i.e., immediately after curing composite resin. On the buccal and lingual surfaces of 35extracted human molar teeth, class V cavities were prepared withthe occlusal margin in enamel and the gingival margin in dentin. They were restored with a hybrid composite resin Z250 (3M ESPE, USA) using an adhesive AdperTM Single Bond 2 (3M ESPE). As rebonding agents, BisCover LV (Bisco, USA),ScotchBond Multi-Purpose adhesive (3M ESPE) and an experimental adhesive were applied on the restoration margins before polishing step or after successive polishing and etching steps. The infiltration depth of 2% methylene blue into the margin was measured using an optical stereomicroscope. The correlation between viscosity of rebonding agents and mciroleakage was also evaluated. There were no statistically significant differences in the microleakage within the rebonding procedures, within the rebonding agents,and within the margins. However, when the restorations were not rebonded, the microleakage at gingival margin was significantly higher than those groups rebonded with 3 agents (p < 0.05). The difference was not observed at the occlusal margin. No significant correlation was found between viscosity of rebonding agents and microleakage, except very weak correlation in case of rebonding after polishing and etching at gingival margin (r = -0.326, p = 0.041).
