초록
연구목적: 본 연구의 목적은 미세 유체 흐름 측정장치를 이용해서 각 상아질 지각과민 처치제의 적용 과정 중 발생하는 상아세관액 흐름의 유동을 관찰하고, 상아질 지각과민 처치제 간 적용 후 투과도 감소의 차이를 비교하고자 하는 것이다. 연구 재료 및 방법: CEJ 5 mm 하방에서 절단한 소구치를 미세 흐름 측정장치에 연결하여 20 cm H2O의 정수압을 가하였다. 치경부에 상하 3 mm, 근원심 4 mm, 깊이 2 mm의 V자 형태의 5급 와동을 형성하고 smear layer를 제거하기 위해 15초 동안 산 부식한 후 상아질 지각과민 처치제를 적용하였다. 사용된 상아질 지각과민 처치제는 Seal&Protect (SP),SuperSeal (SS), BisBlock (BB), Gluma desensitizer (GL), Bifluoride 12 (BF) 이다. 상아세관액의 흐름은 지각과민처치제 도포 전부터 도포 후 5분까지 실시간으로 측정되었다. 결과: 실험에 사용한 모든 상아질 지각과민 처치제는 적용 후의 상아세관액 흐름율이 적용 전에 비해 유의하게 감소하였다(p < 0.05). SP는 GL과 BF에 비해 유의하게 투과도 감소가 나타났다 (p < 0.05). SS와 BB는 BF에 비해 유의하게 투과도감소를 보였다 (p < 0.05). 결론: 지각과민 처치제의 도포 과정 동안 각 처치제의 특징적인 상아세관액의 유동을 미세 유체 흐름 측정장치를 통해 관찰할 수 있었다.
Abstract
Objectives: The aim of this study was to examine changes in the dentinal fluid flow (DFF) during desensitizing agent application and to compare permeability after application among the agents. Materials and Methods: A Class 5 cavity was prepared to exposure cervical dentin on an extracted human premolar which was connected to a sub-nanoliter fluid flow measuring device (NFMD) under 20 cm water pressure. DFF was measured from before application of desensitizing agent (Seal&Protect, SP; SuperSeal,SS; BisBlock, BB; Gluma desensitizer, GL; Bi-Fluoride 12, BF) through application procedure to 5 min after application. Results: DFF rate after each desensitizing agent application was significantly reduced when compared to initial DFF rate before application (p < 0.05). SP showed a greater reduction in DFF rate than GL and BF did (p < 0.05). SS and BB showed a greater reduction in DFF rate than BF did (p < 0.05). Conclusions: Characteristic DFF aspect of each desensitizing agent was shown in NFMD during the application procedure. [J Kor Acad Cons Dent 2010;35(5):313-320.]
