초록

본 연구의 목적은 치간삭제 후 불소 및 수산화인회석 페이스트의 치면 도포에 대한 법랑질 표면의 결정구조 및 재광화를 평가하고자 하였다. 치간삭제 후 1.23% 인산화 불소 및 10% 수산화인회석 페이스트를 치면에 도포한 후 법랑질 표면의 결정구조 변화를 주사전자현미경으로 관찰하고, 법랑질 표면의 칼슘, 인, 불소 함량 등의 변화를 energy dispersive X-ray spectroscopy (ESD)로 분석하였다. 실험결과 10% 수산화인회석 페이스트 도포한 군에서 칼슘함량이 증가하였고 (p < 0.01), 치간 삭제 후 거칠었던 법랑질 표면이 매끄럽고 부드러워졌으며 법랑질 결정구조가 작고 치밀해짐을 관찰할 수 있었다. 이상의 결과는 치간삭제 후 불소 및 수산화인회식 도포가 치면 결정구조 및 재광화에 유리하다는 것을 의미한다.

Objective: The aim of this study was to evaluate the remineralization of interdentally stripped teeth after fluoride gel or hydroxyapatite paste application. Methods: After interdental stripping, 1.23% fluoride gel or 10% hydroxyapatite paste was applied three times a day, with a duration of four minutes, for a week. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were used to compare the change of surface contents and crystal structures before and after the application of fluoride gel or hydroxyapatite paste. Results: EDS analysis indicated that calcium contents were increased after 10% HAp paste application on stripped enamel (p < 0.01). SEM view showed that enamel surfaces in groups of 1.23% APF gel or 10% HAp paste application were smoother than those of control group, which was regarded as filling of the pore structure. And pores between crystal structures in groups treated with 1.23%, APF gel or 10% HAp paste were smaller than those of control group. Conclusions: Application of APF or HAp on stripped enamel could positively influence on the surface contents or crystal structure.
