Abstract

When restoring endodontically treated teeth is the mismatch between fiber post size and post space diameter, the resin cement layer is excessively thick in post space and voids are likely to form in it, thus predisposing to de-bonding. The method to overcome this problem is to reline the fiber post with composite resin. This individual anatomic post improves the adaptation of post to root walls and decreases the resin cement thickness. The purpose of this in vivo study was to evaluate the push-out bond strength of fiber post according to relining procedure and luting agents type used for simplicity of clinical procedure. Forty-two extracted teeth were divides into six groups.(n=7) A1: relined fiber post cemented with Luxacore/all-bons 2, A2: non-relined fiber post cemented with Luxacore/all-bond2, B1: relinind fiber post cemented with Calibra/XP-bond, B2: non-relined fiber post cemented with Calibra/XP-bond, C1: relined fiber post cemented with RelyX Unicem, C2: non-relined fiber post cemented with RelyX Unicem Push-out bond strength was affected by interaction between relining procedure and luting agent type. Relined fiber post presented higher push-out bond strength value than non-relined fiber post and statically significant differences(p<0.05) Cementation with RelyX Unicem showed significantly higher bond strength than other luting agents(p<0.05).

근관치료된 치아의 수복에서 fiber post 크기와 포스트 공간의 직경이 일치하지 않은 경우, 포스트 공간은 두꺼운 레진 시멘트로 채워지게 된다. 레진 시멘트가 두꺼워지면 시멘트 내에 기포가 형성되어 포스트 분리가 발생되기 쉽다. 이런 문제점을 해결하기 위한 방법은 composite resin을 이용하여 fiber post를 relining하는 것이다. 이렇게 형성된 해부학적 포스트는 포스트 공간에 잘 적합하고 시멘트의 두께를 감소시킨다. 이 연구의 목적은 relining 과정과 임상 과정의 간소화를 위해 사용되고 있는 luting agents 종류에 따른 fiber post의 push-out 결합 강도를 평가하는 것이다. 42개의 발치된 치아는 6개의 그룹(n=7)으로 나누어졌다. (A1: relined fiber post를 Luxacore/all-bond 2로 합착, A2: non-relined fiber post를 Luxacore/all-bond 2로 합착. B1: relined fiber post를 Calibra/XP-bond로 합착. B2: non-relined fiber post를 Calibra/XP-bond로 합착. C1: relined fiber post를 RelyX Unicem으로 합착. C2: non-relined fiber post를 RelyX Unicem으로 합착.) Push-out 결합 강도는 relining procedure와 cement type의 상호작용에 의해 영향을 받는 것으로 나타났다. relined fiber post 그룹이 non-relined fiber post 그룹보다 더 높은 결합 강도를 가지며 fiber post relining 과정은 결합강도에 유의한 영향을 가진다.(p<0.05) Luting agent에 따라 모든 그룹에서 RelyX Unicem의 결합강도가 Luxacore/All-bond 2와 Calibra/XP bond에 의한 것보다 유의하게 더 높았다(p<0.05).
