목적: 이번 연구의 목적은 FRC-포스트와 코어가 색상차이에 따라 구별되는 정도를 비교하는 것이다. 연구 재료 및 방법: 실험을 위해 유사한 크기(± 0.5 mm)와 길이(± 0.5 mm)의 발치 한 하악 소구치 9개를 근관 형성하고 충전하였다. 3개의 치근을 체온을 재현하기 위해 37°C 물이 흐르는 가는 실리콘 튜브로 감은 후 cold mounting resin에 매몰하여 각 3개의 치근이 매몰된 총 3개의 시편을 제작하였다. 개개의 시편 치근에는 3종류의 Snowpost®, MACROLOCKTM POST ILLUSIONTM XRO®, FRC Postec® Plus post를 이용하여 각각의 포스트에 맞게 공간을 형성하고 포스트를 접착하였다. 3개의 시편 별로 Luxacore® Dual Blue, Luxacore® Dual A3 및 FiltekTM Z350 XT A1E로 코어를 축조, 시편 별로 다른 코어를 사용하였다. 각 시편에 대해 온도를 낮추기 위한 압축공기를 불 때와 안 불 때로 나누어 디지털 이미지를 촬영하였다. 치과의사 50명과 치과대학 대학생 50명 총 100명에게 어떤 포스트가 코어와 가장 구별이 잘 되는 지를 설문조사 하였다. 결과: Luxacore® Dual Blue에서는 Snowpost®가, Luxacore® Dual A3에서는 Snowpost®가, FiltekTM Z350 A1E에서는 MACRO-LOCKTM POST ILLUSIONTM XRO®가 구별이 가장 잘되었다. 압축공기를 불어 온도를 내리면 나타나는 MACRO-LOCKTM POST ILLUSIONTM XRO®의 색은 포스트와 코어의 구별을 더 용이하게 하였다. 결론: FRC-포스트와 복합레진 코어가 구별되는 정도는 색상차이에 따라 다름을 알 수 있었다.
Abstract
Purpose: The purpose of this study is to evaluate which FRC-posts were more distinguishable from core. Materials and Methods: Nine extracted single-rooted mandibular premolars with similar lengths (± 0.5 mm) and widths (± 0.5 mm) were endodontically treated and obturated. One specimen which the three roots were embedded in a cold mounting resin was made. 3 specimens were made by this method. Post spaces were prepared for the following post system: FRC Postec® Plus, MACRO-LOCKTM POST ILLUSIONTMXRO®, Snowpost®. After three different posts were placed in the roots of a specimen, each three specimens received a direct core build-up: Luxacore® Dual A3, Luxacore® Dual blue, FiltekTM Z350 A1E. Digital images were taken of the post and core with and without air-blowing. We asked to fifty dentists and fifty dental college students which post was more clearly discriminated from the core. Results: In surveys, when core was Luxacore® Dual blue, among three types of posts people more easily discriminated the Snowpost® from core. When core was Luxacore® Dual A3, among three types of posts people similarly more easily discriminated Snowpost® from core. When core was FiltekTM Z350 A1E, among three types of posts people more easily discriminated distinguished MACRO-LOCKTM POST ILLUSIONTM XRO® post from core. People more easily distinguished MACRO-LOCKTM POST ILLUSIONTM XRO® post from core when temperature was lowered by air-blowing. Conclusion: Ability to discriminate between FRC-post and core is different according to color contrast. MACRO-LOCKTM POST ILLUSIONTM XRO® posts are more discriminable when temperature is lowered by air-blowing.
